Abstract

The invention relates to a type of fatty acid proportion and VE content customized edible oil adapted to different dietary patterns. The edible oil is characterized in that: taking a family as a unit, different polyunsaturated fatty acid proportions and Vitamin E contents are designed according to different oil ingestion amount per person per day and different dietary characteristics, a novel approach is provided for solving the problem that different dietary habits are not considered in the prior edible blend oil, especially fatty acid coordination caused by larger difference of amount of each family edible oil. The invention provides a specific scheme which summarizes a series of parameters of the edible oil and calculation formulas of the polyunsaturated fatty acid proportions and VE contents overall considering factors such as human body antioxidant, blood fat reduction, prevention lipid peroxidation, improvement of immunity, apha linolenic acid conversion efficiency and more outside repast, based on fully estimation of the food polyunsaturated fatty acid proportions and Vitamin E acceptable daily intake of China urban residents under various extreme conditions. With 2 to 6 specifications, the customized edible oil with appropriate Fatty acid proportions and VE contents can be provided for populations with different dietary patterns in actual application.

Description

The fatty acid proportion and the personalized edible oil of VE content that adapt to different diet structures

One. technical field: the present invention relates to a kind of personalized edible vegetable blend oil that can play a role in health care to human body.

Two. background technology: fat is one of human most important nutrient, also is the important component part of human body (cell).And edible oil traditional essential food that is Chinese residents also is the important or main source that human body is taken in fat and liposoluble vitamin.Edible oil also should become Chinese residents and regulate targetedly, corrects the incorrect picked-up of food fat acid, and the Main Means that all kinds of fatty acid total amount correct balances are taken in becomes the important sources that human body is taken in the physiology antioxidant.

Except energy and liposoluble vitamin were provided, edible oil and aliphatic acid (particularly unrighted acid) were the hot subjects that the expert of all circles attaches great importance to for the material impact of health always:

(1) correctly picked-up can play an important role aspect prevention and the treatment heart, the cranial vascular disease.Other still have: improve immunity, regulate gene expression, the physiological interaction of coordination iuntercellular, keep rhodopsin normal function, synthesising prostate, improve glycometabolism and insulin sensitivity and avoid lacking the caused various diseases of essential fatty acid.Polyunsaturated fatty acid also plays a very important role growing of the mankind.Along with the development of science and technology, the function new about unrighted acid also constantly is being found and confirming;

(2) incorrect picked-up is harmful: will control the intake except what people had generally recognized to saturated fatty acid, also there is easy generation peroxidatic reaction of lipid in polyunsaturated fatty acid, thereby produces the problem to the hurtful free radical activity oxygen of cell.Improve lipid aspects, polyunsaturated fatty acid when reducing harmful low-density lipoprotein, to human body favourable HDL also decrease.In the continuous found while of the new function of polyunsaturated fatty acid, the disadvantage of excess ingestion is found successively and confirms and cause showing great attention to of all circles;

(3) in the vegetable oil of present single variety, there is not a kind of contained fatty acid composition to meet nutritionist's standard fully.It is the effective and generally acknowledged method that addresses this problem that the various plants edible oil is in harmonious proportion by a certain percentage.

Vitamin E is the antioxidant of food, also is the Human Physiology antioxidant.Human necessary nutrient has been classified it as in sixties nutrition circle in last century, and its physiological function is very important.About the function of vitamin E, still have at present various different opinion, and some function is still waiting further research and confirmation.But about the human body injury of " oxidation " meeting to the people, and vitamin E has stronger antioxidation in human body, and each side's suggestion there is no difference in principle on this problem.The U.S. just began to have had vitamin E quantity delivered numerical value as far back as nineteen fifty the 8th edition RDA, and Chinese Soclety of Nutrition has also formulated vitamin E meals every day and recommended quantity delivered since 1988.

The ready-mixed oil finished product that the present invention sells existing market, disclosed ready-mixed oil patent and the pertinent literature delivered at professional magazine have carried out detailed investigation, find the problem of three aspects of ubiquity.

(1) problem of adaptability aspect existence:

1. " Chinese residents nutrition in 2002 and investigation of health conditions " (hereinafter to be referred as 2002 investigation) by the Ministry of Public Health, the Department of Science and Technology and State Statistics Bureau's organization leadership show: Chinese Urban Residents accounts for 50.3% of total quantity by the fat of edible oil picked-up, and wherein the big city resident is 49%.China is vast in territory, and is populous.The various places resident is owing to exist larger difference in many-sides such as history, cultural tradition, natural environment, economic situations, and dietary is also far from each other.Even the different home in the same area, diet structure also is not quite similar.For example: the higher crowd of edible oil picked-up quantity can reach more than 70 grams every day per capita, and low possible less than 20 grams, maximum and minimum of a value have the above gap of twice.For all kinds of crowds, if do not eat same or same class edible oil (comprising ready-mixed oil) with making any distinction between, all kinds of aliphatic acid of only taking in from edible oil also will have corresponding gap, will certainly cause the serious imbalance of all kinds of aliphatic acid (mainly being polyunsaturated fatty acid) picked-up, unreasonable.

2. although balance is reasonably absorbed aliphatic acid and can be played important health-care effect to human body, edible oil is not health products after all.As the daily food of Chinese residents, that the picked-up of edible oil can not resemble is independent other food, directly edible and normally carry out simultaneously with meals.Meals are movable can not all to carry out in a fixing place, and particularly the city dweller more or less always has some and eats and inferiorly finish in other places.The family dish-cooking uses a kind of new product edible oil, and before this product was not yet popularized, it was another kind of edible oil that the outside is had dinner edible, and this is very general diet structure.Domestic existing ready-mixed oil patent all is that oneself product is among a kind of ecotopia of hypothesis: all edible self-designed a kind of edible oil of three meals in a day are not affected by any external factor.In the primary stage that new product comes out, this condition can only be present among the scientific experiment, can't be put to practical experience of life.The popularization of any one new product all needs to experience long time course, and the such traditional food of edible oil especially like this.The edible oil diversification of varieties of having dinner and absorb in the Chinese residents outside, fatty acid proportion and content of vitamin E gap great disparity.If ignore this reality, regardless of inventing " scientific and reasonable ", its practical application effect all will be had a greatly reduced quality.

(2) problem of polyunsaturated fatty acid intake aspect existence

Although the edible blend oil patent that China is all and the ready-mixed oil finished product on the market are all declared its fatty acid composition and are met the standard that nutrition is recommended, in fact may exist significant deficiency.Too much reach the improper problem of ratio for ready-mixed oil product and the ubiquitous polyunsaturated fatty acid total amount of Patent design, " dietary fat suit intake (AI) " of advising in " DRIs " chapter 4 that Chinese Soclety of Nutrition write in 2000 has four main points to need special emphasis to consider: (1) " dietary fat suit intake " (hereinafter to be referred as fatty AI) refers to whole fat masses of human intake.Wherein both comprise edible oil fat, also comprised other food fats.The two is of equal importance, and is indispensable;

(2) " fatty AI " all is that the percentage that the energy that produced with all kinds of fat accounts for gross energy recently represents.The suitable intake of all kinds of aliphatic acid there is no fixing proportionate relationship between other aliphatic acid except polyunsaturated fatty acid n6, n3 are proportionate relationship;

(3) important prerequisite of " fatty AI " is: the scope that fatty energy accounts for gross energy proportion is between 20%～30% (adult), and the energy proportion that provides for fat surpasses 30% part and should be which kind of fat and there is no concrete recommendation suggestion;

(4) concept of the dietary fat intake of this suggestion use is " suitable intake (AI) ", and is not normally used in the nutrition " recommended amounts (RNI) ".The difference of the two is: " recommended amounts (RNI) is for the absorption target of human body, and is more accurate.And the standard that suitable intake (AI) is too much taken in for restriction may be significantly higher than RNI.Surpass for a long time (AI) such as intake, then might produce toxic and side effect, more careful ".

Our purpose is take ready-mixed oil as means, replenishes and correct the incorrect picked-up of food fat acid, to realize TFA intake balance, rational final goal.So when all kinds of fatty acid proportion of design edible blend oil, the fatty acid composition of edible oil and food and picked-up quantity all will take into full account.But present actual conditions are: nearly all designer all concentrates on whole notices on the fatty acid proportion of ready-mixed oil self, and has ignored edible oil and current picked-up situation (composition, quantity) and these the most important factors of development trend of food fat.Up to now, existing product, patent comprise that the document that is published on the professional magazine is showed no comprehensively and accurately research.Edible oil intake 25 grams that require in " Diet pagoda " that has the designer that Chinese Soclety of Nutrition is recommended/day as design considerations.Notice, every days 25, gram only was the ideal value that Chinese nutritionist recommends, the present average edible oil intake of China resident is this ideal value head and shoulders above." 2002 investigation " shows that National urban resident is edible oil amount 44 grams/day per capita, and wherein the big city has reached 45.9 grams/day.Although the designer who has has considered meals Diet pagoda recommended amounts and current average level, edible oil quantity gap is not taked targetedly measure.Edible oil picked-up quantity and real gap that more designer does not then relate to this problem or setting at all are more greatly different.For the content of the food fat acid beyond the edible oil, designer or be defined as by not considering being difficult to perhaps simply avoids this problem, directly with ready-mixed oil fatty acid proportion fatty acid proportion as a whole.Also some designer just subjectively infers: the aliphatic acid beyond the edible oil is take saturated fatty acid as main, and then it is all calculated is saturated fatty acid.In daily food, saturated fatty acid is not general above 50% kind.Even the edible pork that frequency is the highest, fat content is larger of Chinese residents, the average content of its saturated fatty acid is also in 50%.Special nutrition survey confirms that also saturated aliphatic acid generally only accounts for about 1/3rd of total amount in the food fat acid.Food fat acid composition is not made the actual intake gap of labor or valuation and resident to be crossed and mostly will cause ready-mixed oil fatty acid proportion design mistake.

Under normal circumstances, the dietary that comprehensively changes one family is to be difficult for realizing.And the food fat intake approaches or above the edible oil intake, the difficulty of correcting incorrect food fat acid with rational edible oil aliphatic acid is just larger.The average absorption level of National urban resident fat in 2002 is 85.5 grams/day, and the proportion of edible oil and food fat amount is 50.3%: 49.7%; The per day absorption level of big city resident's fat is 90.7 grams, and the proportion of edible oil and food fat amount also is 51%: 49% that relatively approaches.In this case, only have the composition of labor food fat acid, the fatty acid proportion design of edible oil could shoot the arrow at the target.For Chinese Urban Residents fatty diet present situation, there is no question about for control saturated fatty acid intake.Only have the minority kind to contain more saturated fatty acid in the vegetable oil, as long as will not adopt, need not take special measure to achieve the goal; Polyunsaturated fatty acid is a double-edged sword: on the one hand its belongs to that human body can not synthesize voluntarily and must be from the direct essential fatty acid of picked-up of food, and picked-up can be satisfied physiological requirements and human body is played important health-care effect, numerous disease is played preventive and therapeutic action in right amount.Because there is the disadvantage that easily produces lipid peroxidation in polyunsaturated fatty acid, long-term excess ingestion then can damage human body on the other hand.Have research to point out: if excessive polyunsaturated fatty acid does not have the protection of enough antioxidants, the harm that human body is brought is not second to saturated fatty acid.Grease production enterprise makes this problem make the matter worse to the one-sided of antioxidant especially.So the polyunsaturated fatty acid composition is most important key in the ready-mixed oil design.By initial analysis and the measuring and calculating that the highest 16 group foods of the daily edible frequencies such as rice, face, other paddy, potato, beans, vegetables, fruit, pork, poultry, other poultry meat, milk, egg, fishes and shrimps, nut, cake, candy and goods fatty acid composition thereof are carried out, the polyunsaturated fatty acid average that China big city resident absorbs the food beyond edible oil every day is about about 10 grams, and its energy accounts for gross energy 4.3%.For the crowd of greasy diet structure, the energy that the polyunsaturated fatty acid that only absorbs from food fat average every day provides may reach gross energy 7%, even more more.Big energy Ratios like this is neglected the consequence that causes must be: the polyunsaturated fatty acid excess ingestion.Take a ready-mixed oil patented product that suitable popularity and occupation rate are arranged at national edible oil market as example, concrete analysis ready-mixed oil polyunsaturated fatty acid is taken in the representational problem that exists in the quantity design: the ready-mixed oil ratio of this Patent design is saturated fatty acid: monounsaturated fatty acids: polyunsaturated fatty acid equals 0.27: 1: 1, is equivalent to 11.9%: 44.05%: 44.05%.National big city in 2002 is solar eclipse oil quantity 45.9 grams per capita, and wherein aliphatic acid calculates by 95.5%, and the polyunsaturated fatty acid of taking in by edible oil is 19.3 grams.A big city resident per capita day absorption gross energy is 2098 kilocalories, polyunsaturated fatty acid energy by the edible oil picked-up has accounted for gross energy 8.3%, even the polyunsaturated fatty acid in the food is average level (4.3%), the proportion that the polyunsaturated fatty acid energy accounts for gross energy surpasses 12%.This result only is the data with the average edible oil intake measuring and calculating of national big city resident.If day edible oil quantity reaches 58 grams per capita, only the polyunsaturated fatty acid energy by the edible oil picked-up has namely surpassed the upper limit (10% gross energy) that the nutritionist generally admits.A nationwide survey report shows that every day, food ration just reached 58.3 grams to the ready-mixed oil eater before more than ten years per capita.The average energy that such crowd's polyunsaturated fatty acid provides has accounted for 14.8% of gross energy, surpasses the suitable intake (AI) 48% of fat of Chinese Soclety of Nutrition's suggestion, and the amplitude that exceeds standard is very big.Also pay particular attention to: the index that surpasses is not recommended amounts (RNI), but suitable intake (AI), one of important implication of suitable intake (AI) namely: " this is the index that restriction is too much taken in "

In addition, we find that also the considerable public (comprising part insider and ready-mixed oil designer) reasonably absorbs ratio " 1: 1: 1 " to all kinds of aliphatic acid of human body and exists Serious Misunderstanding or one-sided.This formulation of in fact, nutrition circle, medical circle should have important prerequisite: namely the fatty energy that provides accounts for gross energy 20～30%.Broken away from this prerequisite, thought no matter what degree fatty energy Ratios reaches, and S, M, P all respectively account for 1st/3rd, not science or even extremely harmful.To the year ends 2002, Chinese big city resident fat energy Ratios average level has reached 38.4%.In the actual life, it is 40～45% rare that the energy that fat provides reaches, have in addition up to 50%.If do not add prerequisite, general respectively account for 1/3rd with S, M, P and calculate, polyunsaturated fatty acid reasonably absorbs standard will reach 13%～15% even up to more than 16%, and this index obviously is too high.Up to now, the recommended value of only having the U.S. food nutrition committee (FNB) to recommend in 2005 is: fatty energy Ratios 20～35%, the polyunsaturated fatty acid energy accounts for the proportion of gross energy: n6 family 5～10%, n3 family 0.6～1.2%, being equivalent to the maximum specific weight that the polyunsaturated fatty acid energy accounts for gross energy is that 11.2%, WHO/FAO advises also that in July, 2,009 11% is the upper limit.The polyunsaturated fatty acid energy that other international organizations, country's (comprising Chinese Soclety of Nutrition) and numerous experts and scholars recommend is equal to or less than 10% of gross energy.Although there is no at present very accurate unified authoritative standard for " excessive ", but surpassing in right amount for a long time (is the AI value that the nutritionist recommends: 10%～11% gross energy), and do not add any restriction, obviously there is suitable risk in the way with 1/3rd ratios increase polyunsaturated fatty acid simply.In fact, from the physiological requirements of human body, the increase of TFA and failed call polyunsaturated fatty acid must increase accordingly.Before the monounsaturated fatty acids effect is not taken seriously, nutrition circle, medical circle were once relatively emphasized this index of P/S, and have complaints and think that polyunsaturated fatty acid can reach 1/2nd (namely 1: 1: 2 or surpass this ratio) of total fat mass, in addition broadly with content of polyunsaturated fatty acid as the standard of estimating the edible oil nutritional labeling.So far still have many people's publicity, praise highly take polyunsaturated fatty acid as main corn oil, sunflower seeds wet goods, and the unilateral edible health-care oil of it being described as brain tonic.But continuous progress and development along with science and technology, people are when having confirmed that excessive polyunsaturated fatty acid can work the mischief to human body, be subjected to epidemiology survey result's inspiration, be familiar with gradually the effect of monounsaturated fatty acids: monounsaturated fatty acids is close with the polyunsaturated fatty acid effect in the effect that reduces cholesterolemia, triglycerides, LDL-C, but do not have the disadvantage that polyunsaturated fatty acid easily causes lipid peroxidation and reduces HDL, " significant with monounsaturated fatty acids replacement saturated fatty acid ".There is no need to emit the risk of certain (or potential) on an amount of basis, to go again to increase the intake of polyunsaturated fatty acid fully.

It is considered herein that: comprehensively, correctly understanding 1: 1: 1, should be to be to carry out under 20～30% the prerequisite at the total fatty energy Ratios of restriction, and namely 10% gross energy should be the upper limit of polyunsaturated fatty acid picked-up.If fatty energy Ratios surpasses 30%, the part of increase should be monounsaturated fatty acids, and can not increase simultaneously in proportion saturated fatty acid and polyunsaturated fatty acid.In view of the mean value of Chinese residents fat energy Ratios has substantially exceeded 30%, the ratio of S: M: P at least should by be adjusted into 1 at 1: 1: 1＜:＞1 :≤1, prevailing view tends to 1＜: 1.5～2: 1≤or near this ratio, the higher monounsaturated fatty acids ratio of opinion is arranged also.Certainly, also will taking into account on the other hand of problem: polyunsaturated fatty acid belongs to essential fatty acid, if the long-term mistake of its intake is low also unfavorable to health.Weigh with the polyunsaturated fatty acid total amount, China resident is under normal meals condition at present, and rare polyunsaturated fatty acid total amount is absorbed not enough problem.(but n3 series fatty acid intake is on the low side to be ubiquitous problem).In addition, exist at present the negative comment of only a few for the effect of monounsaturated fatty acids, but these suggestions and research do not obtain epidemiology survey result's support yet, and the epidemiology survey practical basis of nutrition theory normally.

(3) problem of vitamin E picked-up quantitative aspects existence

One of key character of vitamin E is fat-soluble.The main source that China resident absorbs vitamin E is vegetable oil.Nationwide nutrient health investigation shows: the vitamin E that the city dweller absorbs by vegetable oil accounted in 1992 and accounted for 57.4% in 69.3%, 2002 year.Although weigh by average level, the intake of Chinese residents vitamin E has reached suitable intake (AI), all kinds of edible vegetable oils because kind, the place of production, and processing technology different, the content of its vitamin E has the difference of great disparity.Even the vegetable oil of same kind also has very large gap between different manufacturers and even the same producer different batches.If add this key factor of picked-up edible oil quantity gap, can infer has considerable resident's vitamin E intake well below the suitable intake of the suggestion of Chinese Soclety of Nutrition.Present ubiquitous problem is: numerous researchers and the producer all concentrate on anti-oxidant in edible oil processing, the storage to notice, and many manufacturers use artificial synthetic antioxidant to solve problem.The edible olein of planting is practiced the vitamin E that distillates in (deodorization) process generally all becomes another kind of care merchandise or health products as byproduct raw material-natural VE, and the vitamin E in the vegetable oil then is in the surplus situation what how much are calculated.Even to refine vitamin E as purpose, normal concise processing generally will not lost about 30% yet, even more more.And the grade of edible oil higher (for example edible higher salad oil of rate of city dweller), the loss of vitamin E is just larger.Because the food additives national standard is " using in right amount by need of production " to the content requirement of vitamin E in the vegetable oil.The edible vegetable oil of selling on the market, except the relatively high kind of minority content, many vegetable oil do not mark substantially to content of vitamin E.When discussing the edible oil oxidation preventive content, scholars also just are confined to the needs of the polyunsaturated fatty acid of edible oil itself, the suggestion and the research that rarely consider a problem from the Human Physiology demand.Human body demand to vitamin E on physiology does not obtain due attention in the grease production link.

Three. summary of the invention:

The present invention mainly solves the at present problem of ubiquitous three aspects of edible blend oil:

(1) fatty acid proportion is single, can not adapt to edible oil picked-up quantity different crowd needs, can not adapt to Chinese Urban Residents and have dinner in the family at present and the have dinner diet structure present situation of coexistence of outside;

When (2) the ready-mixed oil fatty acid proportion designs, inconsiderate to edible oil, food fat acid intake, thereby the ready-mixed oil fatty acid proportion is lost contact with reality, and subject matter is that the general bigger than normal and linoleic acid of polyunsaturated fatty acid proportion, leukotrienes Proportionality design are improper;

Anti-oxidant problem when (3) only considering edible oil processing, storage, and ignored the anti-oxidant of inside of human body and other physiological requirements, the vitamin E minimum content is not given attention.Especially for the excessive general too much present situation of polyunsaturated fatty acid intake that causes of Chinese residents edible oil quantity gap, the problem of the solution part population vitamin E intake deficiency of shooting the arrow at the target is more urgent;

For overcome the above problems comprehensively, crowd for different diet structures, the present invention creatively proposes " fatty acid proportion and content of vitamin E are personalized ", is the family of different diet structures, development fatty acid proportion and the different personalized edible vegetable blend oil of content of vitamin E.

Analyze by inquiry and can find, although individual edible oil and food fat acid picked-up quantity have larger gap owing to dietary is different, the same family member diet structure is basic simlarity.Even if family sets up the initial stage and can have some differences, but As time goes on and gradually these gaps can dwindle, even reach unanimity.The same family member is caused by factors such as age, sex, activity intensities in the gap aspect the fatty acid uptake absolute quantity.If being converted into that the normal man weighs, these factors do not consist of greatly different difference.In addition, for the reality that the city dweller has more outside to have dinner, the present invention also gives and sufficient consideration this at the design aspect of fatty acid proportion and content of vitamin E, makes every effort to take into account comprehensively.

(1) design principle, major parameter and foundation

1. accommodation: " 1 " macro-scope: because the imbalance of economic development, the less-developed rural area resident's problem of food and clothing of part solves not yet fully.Even if in the city, the resident of many middle and low incomes do not have yet enough economic capabilities go to take into account fatty acid proportion rationally whether.This part crowd is lower owing to income in addition, and fat intake is also relatively less, thereby it is also not very urgent in present stage to solve the relevant issues that too much caused by fat intake (comprising polyunsaturated fatty acid).So, accommodation is defined as taking in relatively high resident and belongs to the clinical nutriology category in prevention and treat the crowd who diet is had aspect the so-called rich man's disease (such as cardiovascular and cerebrovascular disease, diabetes etc.) higher or specific (special) requirements in primary stage the present invention.And the feature of this class crowd aspect nutrient intake is similar to big city and booming income crowd.Therefore, the relevant nutrition survey data of quoting are mainly derived from big city resident or other regional booming income residents' ASSOCIATE STATISTICS data.Because society is always at continuous development and progress, resident's living standard is also in continuous improve.Eye with development is looked at problem, and the present invention is applicable to the city of normal meals scope." 2 " except some obviously exceed the family of normal meals custom, the scope that edible oil of the present invention can not adapt to fully also includes the crowd of some special hobby or needs, such as the many especially food of the oil content such as nut, fat meat, fried food of often ingesting in a large number and take the higher medicine of fat content, health products etc.But for such crowd, edible edible oil of the present invention can make its incorrect aliphatic acid take in the correction that obtains to a certain degree.

2. edible oil, food fat and caloric intake amount present situation and development trend:

Nineteen eighty-two～2002 year China (city) resident everyone edible oil every day and food fat intake situation of change table 1

Table 1 shows: 1982～2002 years, China resident fat intake was constantly soaring with the speed of 0.86 gram/day every year on average over 20 years.Sociologist, nutritionist think: it is the problem of whole world general character that resident's dietary fat amount increases with the income raising, also is the characteristics of country with economies in transition, and reverse this situation is difficult.The effort through more than 30 years only drops to about 33% the American at present after fatty energy Ratios reaches 36%～37% the seventies.The present situation that faces of China should be even more serious than the U.S. then.The nutrient health investigation in the whole nation in 2002 is extremely pass by nearly time more than 8 years at present, and still is in China's rapid economic development this period, the stage that the resident living level further improves.Infer that the average intake of present fat should also have then than investigation the increase of certain amplitude.Because the average fatty energy Ratios of China city dweller has substantially exceeded the generally acknowledged upper limit (30%), wherein the big city has reached 38.4% on the other hand.And this only is average level in 2002, and necessarily having a considerable amount of residents' fat energy Ratios will be considerably beyond average.So high dietary fat amount and the negative effect that brings thus, after one's own heart, cranial vascular disease, hypertension, onset diabetes rate increase, phenomenon very general and these diseases and the positively related relations of fatty intake such as high fat of blood, overweight, obesity have caused the attention rate that people are more and more higher.The total intake of expectation city dweller fat will substantially be stagnated after reaching certain level, pace up and down, then slow decreasing under effort in many ways.Further analyze and it can also be seen that the increase of fatty intake mainly concentrates on edible oil.Previous decade increases by the 1.1 gram/day for human beings every year on average, and rear ten years slowdown in growths increase by the 0.71 gram/day for human beings every year on average.City dweller in 2002 per capita edible oil picked-up every day quantity is 44 grams, big city 45.9 grams wherein, and big and medium-sized cities booming income crowd has reached 48.4～49.4 grams per capita, and the food fat intake then changes not quite.Another variation is: according to present development trend, city dweller's animality edible oil will be replaced by vegetable oil gradually.Especially in the big city and well-to-do family, present basic edible animal oil not.

The Chinese residents energy is taken in: national per capita share was 2250.5 kilocalories/day in 2002, and wherein the big city is 2098 kilocalories/day.From development trend, along with society makes constant progress, the resident living level improves constantly, and the average intake of gross energy is also in year by year slip.City dweller's caloric intake amount in 2002 only is 89% of recommendation (RIN).Compare with National survey in 1992 and to have reduced during the decade 10.9%, megapolitan's group mean intake only reaches 87% of recommendation.Because this value has been reduced levels, although future may also have certain decline, amplitude can be very not large, can ignore.

3. every basic engineering parameter

(1) gross energy: among the present invention, be the proportionate relationship between n6 and n3, there is no absolute proportionate relationship between other aliphatic acid, all kinds of aliphatic acid intakes all represent with the ratio that its energy accounts for gross energy.Gross energy adopts two standards as design basis: take 2098 kilocalories/day of " 2002 investigation " average gross energies of big city resident for the mean value radix, calculate the aliphatic acid ceiling capacity than the time, take 1.2 times of mean values as radix (2098 * 1.2=2518 kilocalorie).Measuring and calculating aliphatic acid least energy than the time, take mean value 75% as radix (2098 * 75%=1573 kilocalorie).

(2) edible oil is taken in quantity and relevant issues: edible oil is main (important) source that human body is taken in fat and vitamin E, and is great on TFA ratio, total amount and the impact of vitamin E total amount of human body absorption by all kinds of aliphatic acid and vitamin E that edible oil is taken in.As previously mentioned: do not have a kind of contained fatty acid composition to meet nutritionist's standard fully in the vegetable oil of single variety.Existing ready-mixed oil polyunsaturated fatty acid ratio is generally higher on the market, and n6 and the ratio of n3 also have no idea to take into account the crowd of different edible oil quantity at all, and the content of vitamin E is also generally on the low side in the edible oil.How to have addressed these problems two thinkings:

The one, is according to polyunsaturated fatty acid total amount and n6 in the individual eating patterns: n3 ratio designs respectively the ready-mixed oil of polyunsaturated fatty acid different proportion;

The 2nd, designs respectively the ready-mixed oil of different proportion polyunsaturated fatty acid and content of vitamin E according to " per capita every day take in edible oil quantity " (among the present invention referred to as edible oil quantity).

The problem that enforcement the first thinking need to solve mainly is the setting of dietary fat attribute and dietary fat number of types.

Attribute is set: the meals attribute that aliphatic acid is taken in can be determined by two kinds of methods.

＜1〉visual sense: meals character is divided into three types such as greasiness, mean type, light type with the fancy grade to food fat.But all are processes of a gradual change between mean type and greasiness, mean type and the light type, can not quantize a clear and definite boundary, can only play the effect of two types in the practical application.In addition, from literal understanding, greasyly and light as if belong to two kinds of distinct meals types, the difference of should being not difficult.But the factor in the practical operation is intricate, only judges with visual sense and makes mistakes easily.For example: be all meat, the fat content of pork and beef, poultry differs greatly, and the meat different parts fat content of same kind also has a long way to go; Its fat content of the fish of different cultivars has the gap of several times; Though bean product belong to vegetable dish series, mouthfeel is also partially light, and the fat content of itself may be higher than some plenty of meat and fish dish.Moreover the fat content of food and content of polyunsaturated fatty acid be positively related relation not necessarily.The species that fat content is high, content of polyunsaturated fatty acid may not be just necessarily very high.The food that total fat content is general, content of polyunsaturated fatty acid but may be very high; Simple with sensation intuitively judge content of polyunsaturated fatty acid what and unreliable, can only play auxiliary reference role at most.

＜2〉aliphatic acid classification: the incorrect picked-up of food fat acid beyond the edible oil is the target that is repaired, and it is correct analyzing theoretically this thinking.But the problem that exists is the implementation difficulty: for general family, calculating or estimation are too large by the obvious difficulty of polyunsaturated fatty acid quantity of daily food intake one by one.Through the screening to various ways, relatively the way of reality is qualitative roughly to n3 series intake: all kinds of crowds are divided into three meals types such as more, average, less.As previously mentioned, can only play the effect of more and less two types in the practical application.Through measuring and calculating, two number of types are very few, and it is very undesirable to remedy the unbalanced effect of fatty acid uptake that causes because of edible oil picked-up quantity gap.Meals type design quantity is as surpassing 2, and then the analysis of each domestic food fatty acid structure needs to obtain the guidance of professional.Too the requirement of specialty has increased the enforcement difficulty of this scheme.Really accomplish in the present circumstance accurate analysis, not only general professional is difficult for finishing, it is implemented difficulty even is equivalent to some special scientific research project: except needs carry out the dietary survey of standard, the problem that exists also has: 1. up to now, existing authoritative data " food fat acid component list (2002), (2004) ", add various publications, document is reported successively, except edible oil, the food variety of known fatty acid composition is no more than 300.Aside from its accuracy, representativeness how, single with regard to quantity, also differ greatly with the daily edible food variety quantity of Chinese residents; 2. with the difference of group food owing to growing environment, plantation (raising) condition, segmentation kind and production and processing mode, its fatty acid composition is far from each other; 3. for family, the culinary art link also can not be ignored the impact of aliphatic acid retention; 4. by finding the analysis of the daily diet structure of Chinese residents and food fat acid composition, have a kind of aliphatic acid classification of eating patterns to be difficult to segmentation: the n3 intake is less again in by the more n6 of food intake beyond the edible oil, and this eating patterns are very common again.In any case this is a bottleneck problem of also not walking around.This problem does not solve, and distinguishes, judges that by increasing meals types (above 2) way that food polyunsaturated fatty acid composition is dealt with problems will be difficult to effective enforcement.So dealing with problems as means take division dietary fatty acid picked-up type that present stage is simple also has many difficulties to need to solve.But this thinking still can be received certain effect as the ancillary method of other ways: for example only for owing to obviously surpass general normal ingest custom and the crowd of more or less certain aliphatic acid of picked-up, perhaps investigate and analyse, filter out the representational meals type of regional area by the meals (fat is special) of certain scale and for outside general some the adjustment measures that can take with oil product kind, the number of times of having dinner in local restaurant of having dinner.

Weigh the advantages and disadvantages, because edible oil occupies very important ratio in total fat picked-up quantity, and has concrete quantized data, every day, edible oil quantity was accomplished than being easier to per capita and calculate comprehensively.Proceed from the reality, the feasibility of the second thinking is better than the first thinking greatly.But for the resident (for example fisherman family and linseed oil, the perilla herb oil place of production) of some specified conditions, occupation, environment and the resident family of some special diets custom, the n3 series polyunsaturated fatty acid that its member takes in obviously exceeds average level or the higher level (centre also has some transiens) of normal meals family, also should give for this meals characteristics (meals type) and takes into account.Such way is equivalent to take the second thinking as main, and the first thinking aliphatic acid is categorized as auxiliary mating type.

Take edible oil quantity as main, food fat acid is categorized as auxiliary, and the design personalized ready-mixed oil has two schemes.Two scheme principles are identical, and the emphasis that the main distinction considers a problem when being edible oil quantity is set emphasizes particularly on different fields, thereby application mode is also different.

The first scheme: calculate the standing specification of ready-mixed oil with edible oil quantity typical value, be called for short standing specification method: specific practice is take family as unit, and the meals characteristics are divided into three types.

＜1〉III type: picked-up n3 series polyunsaturated fatty acid a lot (obviously exceeding diet structure common in the daily life).But notice that not all sea (water) product all contains more EPA, DHA.Some sea (water) product does not only contain EPA, DHA, even the content of n3 series is all few, some in addition be zero, need to have the personnel of certain professional knowledge to participate in screening;

＜2〉II type: meals are not subjected to ectocine substantially, i.e. the seldom outside crowd who has dinner;

＜3〉I type: the type that accommodation is the widest.I.e. all meals type except the III type.

Each meals type is therefrom screened 2～4 edible oil quantity as typical value take edible oil quantity per capita as radix again.Through measuring and calculating, determine that I, II type edible oil quantity typical value are: 60 grams, 53 grams, 45 grams, 20 grams; III type edible oil quantity typical value is: 60 grams, 20 grams; Calculate corresponding polyunsaturated fatty acid ratio and content of vitamin E respectively as the main design parameters of I, II, the standing specification of III type ready-mixed oil with edible oil quantity typical value.The ready-mixed oil that other edible oil quantity are suited is formulated by a certain percentage by standing specification.

Mainly consider three factors when standing specification method edible oil quantity typical value is selected:

＜1 〉. raw material and Cost Problems: ready-mixed oil of the present invention is as primary raw material with tea oil.Refining tea oil linoleic acid ratio is generally between 8%～10%.According to measuring and calculating, every day, edible oil quantity was higher per capita in the same type, and the linoleic absolute ratio of the edible oil that is suited should be lower, thereby required also will reduce accordingly as the tea oil linoleic acid ratio of primary raw material.Not only raw material sources are not extensive to cross low linoleic acid ratio, and cost also can increase.So will reduce the use chance of low ratio linoleic acid tea oil in the raw material as far as possible;

＜2〉although. the standing specification of each type only needs two specifications of head and the tail can make other any specifications, and the factor that needs to consider is: the zone that corresponding edible oil quantity typical value covers in the prevailing linoleic acid ratio of tea oil (8%～10%) scope is substantially identical with the zone of the percent profile density maximum of the average edible oil quantity of Chinese Urban Residents and edible oil quantity;

＜3 〉. the foundation that minimum, the highest edible oil quantity typical value is set;

Standing specification method edible oil quantity typical value is selected foundation:

The I type: 60 grams are the typical value of higher edible oil quantity 1..Although may be larger to this type crowd's coverage rate as higher edible oil quantity typical value such as 63～65 grams with larger numerical example.But during N=0, the ready-mixed oil polyunsaturated fatty acid ratio that 60 gram edible oil quantity are suited is: linoleic acid 8.3%, leukotrienes 7.0% need to can not be higher than about 7.2% as the tea oil linoleic acid composition of raw material.The tea oil raw material linoleic acid ratio that is suited greater than 60 gram edible oil quantity will be lower than 7%, and the source is not extensively, cost also can be higher; 2. 60～70 gram edible oil quantity crowds eat linoleic acid 8.3%, leukotrienes 7.0% edible oil, although the polyunsaturated fatty acid total amount is slightly high, but still within scope of design, and n6: n3 ratio more tends to ideal value;

45,53 grams: 1. the linoleic acid ratio that suited of edible oil quantity 45 gram crowds be 11.1%, leukotrienes ratio 9.3%.Need to be as the tea oil linoleic acid proportion about 10% of raw material.This is the prevailing kind of tea oil, source and the equal no problem of cost; 2. the average edible oil quantity 44 of Chinese Urban Residents restrains, average edible oil quantity 49 grams of big city resident.45～53 grams and near scope have covered the most intensive zone of city dweller's edible oil quantity percent profile; 3. 53 restrain ready-mixed oil linoleic acid ratio 9.4%, the leukotrienes ratio 7.9% that edible oil quantity crowds are suited, require raw material tea oil linoleic acid ratio 8.3% within common content 8～10% scopes of tea oil linoleic acid common variety.If do not establish 53 grams for simplifying specification, edible oil quantity all need to be by 60 grams, two specification preparations of 45 grams at the ready-mixed oil that the crowd suited of 45～60 gram scopes, increase the use chance of low linoleic acid ratio (7%) tea oil, be unfavorable for cost control and tissue production; 4. owing to the 2. described reason, 45,53 grams can be used as directly edible specification (being equivalent to classification method specification) and needn't preparing for the second time of most edible oil quantity crowd (38～63 gram) in some cases;

20 grams: as the typical value of low quantity.Although the edible oil quantity of some family may be lower, the suitable intake that Chinese Soclety of Nutrition is recommended is 25 grams.Cross low edible oil quantity and be unfavorable for that health keeps normal physiological function, should progressively increase absorption.III type: 60 grams, 20 grams: the setting of its numerical value also is to prepare other specifications and select the numerical value identical with the I type with the I type for convenient except considering the reason identical with the I type.Because the ready-mixed oil leukotrienes ratio lower (3.5%) that 60 gram edible oil quantity crowds are suited thereby the linoleic acid ratio of needed raw material are higher than the I type, 60 grams can replace the effect of 53,45 grams, so the III type is only established 2 specifications through measuring and calculating; The whole specifications of II type by I, the preparation of III type, do not need to arrange standing specification fully.

Alternative plan: Chinese residents edible oil quantitative range is divided into some class, and the present invention is referred to as edible oil classification or classification.Each edible oil classification is definite except needs are considered the problem of the first scheme in the classification method, and emphasis is also wanted following three contradictions of balance:

＜1〉edible oil quantity should be calculated take family as unit per capita.Member in the same family, although its dietary is roughly the same, but also can not be in full accord: for example, also can be different according to different each dish of food variety edible oil quantity for cooking, each member of family can not evenly ingest to every kind of dish, and therefore the quantity that edible oil is taken in can produce a certain distance.

＜2〉city dweller kinsfolk partly eats and time externally has dinner unavoidably, and everyone the outside frequency of having dinner also can't be accomplished in full accord.Have dinner edible oil kind and the dish of ingesting of outside also has very large uncertainty with oily quantity.

＜3〉consider from ready-mixed oil producer aspect that the scope that as far as possible enlarges edible oil intake of all categories can reduce product specification, be convenient to tissue production.But the excessive scope of every classification can cause the interior projects scale value relevant with minimum intake with edible oil maximal oxygen taken amount of same classification to attend to one thing and lose sight of another; Need the aspect to consider a problem from human body: every class scope is less, and desired value is more accurate.But every categorical measure scope is too small, will increase product specification, increases the difficulty of production, process of operation.Simultaneously, too much specification both inconvenient consumer is judged, is selected, and the problem that a classification edible oil can't adapt to the same family member also can occur.Through measuring and calculating, Chinese residents edible oil quantity is divided into 6 edible oil classifications, can satisfy design object of the present invention under certain condition.Table 2

The square root of median=maximum and minimum of a value product, each classification median effect in calculating is identical with the first scheme edible oil quantity typical value, when calculating the polyunsaturated fatty acid ratio with edible oil quantity all with the median substitution.For guaranteeing the vitamin E intake, content of vitamin E calculates with minimum of a value of all categories.

The main points of alternative plan are: the adaptability of same edible oil classification and the categorical measure feasibility aspect production and operation.For addressing these problems, value range of all categories all leaves relatively large juxtaposition.For example median of all categories is identical with the maximum of next classification, identical, the adjacent classification of median of minimum of a value and next classification has overlapping about 20%, and same classification maximum and minimum of a value also have the gap more than 40%.Its objective is＜1〉so overlapping covering can make the crowd of average daily edible oil quantity 24～58 grams have at least simultaneously two classifications to select, the minimum of a value of the maximum of 3～6 classes, 1～4 class all has three classifications to select simultaneously.Can cover whole members of normal meals family;＜2〉even because a variety of causes is inaccurate to the average daily edible oil quantity calculating of this family, also be unlikely to have broken away from valuation scope of the present invention, to guarantee reliable adaptability;

Pluses and minuses are relatively: two schemes there is no essential distinction, some the time in addition can be combined with, but cut both ways.

The advantage of standing specification method is that the ready-mixed oil parameter that different edible oil quantity are suited can be prepared flexibly according to actual conditions, the design object order of accuarcy is higher.Although standing specification method also will face edible oil quantity gap problem in many cases, its specific aim and accuracy are better than the classification method.And the standing specification of product is also few, is convenient to organize production and operation.When the objective condition of food fat acid exhaustive division possessed, Almightiness type at most only needed six specifications can modulate the crowd that almost can adapt to whole meals types.The shortcoming of standing specification method is need to be through two subharmonics, can be with to operator and consumer and serve inconvenience;

The advantage of classification method is factory's trimmed size that directly dispatches from the factory, and can directly eat, needn't be through two subharmonics.Shortcoming is that the design object accuracy is lower than standing specification method: only have median identical with standing specification method in the design object of all categories.In the more situation of externally having dinner, polyunsaturated fatty acid total amount value of reaching capacity (or exceeding standard by a small margin), n6 when actual edible oil quantity is same classification maximum: n3 ratio no problem; When actual edible oil quantity is same classification minimum of a value, n6: n3 maximum ratio reach capacity (or exceeding standard by a small margin), polyunsaturated fatty acid total amount no problem.The second classification cost of application quantity maximum is also slightly high in addition;

The present invention is decided to be the standing specification method of the first scheme according to measuring and calculating and investigation with the enforcement first-selection in the practice, and the classification method is used as deposit temporarily.But do not get rid of according to market demand and release in some cases classification method ready-mixed oil.

Illustrate: 1. family of the present invention comprises the group that jointly carries out most of meals activity, such as children, the student of boarding system and have dinner in the employee of collectiveity canteen etc.; 2. calculate per capita every day during edible oil quantity, the member in the same family needs to calculate behind the folding normal man coefficient according to factors such as sex, work (activity) intensity, body weight, age bracket and gestation, lactations again; 3. edible oil quantity refers to edible everyone average daily quantity of edible oil of the present invention.If not all having dinner at home, need to convert behind each meal time edible oil quantity coefficient in the estimation family.4. because the variation of objective condition, for example climatic variation, rearing new variety, refining processing technology change and other factors cause the raw fatty acid composition to change, the average edible oil quantity of resident and percent profile variation etc., the numerical value of edible oil quantity typical value, quantity and edible oil classification median, quantity etc. can be set as required separately.

(3) all kinds of aliphatic acid are taken in design phiolosophy, principle and the concrete quantitative value that accounts for gross energy ratio, quantity

Guiding theory about the setting of aliphatic acid intake

According to China dietary nutrition of urban residents element picked-up situation and development trend, it is considered herein that: at present widely publicity, become necessity that the formulation of " S: M: P is 1: 1: 1 " that many people design the guiding guiding principle of dietary fat intake has worth discussion to a certain extent: this aliphatic acid is several to see eighties of last century the seventies the earliest than several formulations.(World Health Organization in 1974 and the World Food Programme are proposed by the part expert in a dietary fat academic discussion in Rome, but do not form final recommendation suggestion.) at first, the prerequisite of this ratio formulation is that total fatty energy Ratios will have a limit.(Chinese Soclety of Nutrition propose suitable intake be 20～30% gross energies) Chinese residents at the fatty energy Ratios of the 1970s and 1980s all below 30%.Weigh in 1: 1: 1 ratio, all kinds of fatty acid uptakes are still within rational scope.But entered since the nineties, along with rapid development of economy, huge variation has occured in the Chinese residents diet structure, wherein is exactly that fat intake increases sharply the most significantly.Substantially exceeded 30% to the average fatty energy Ratios of Chinese residents in 2002, wherein the big city resident is near 39%.From development trend, this index is also slowly soaring, at least at sign that also can't see at present decline.Under these circumstances, surpass 30% part and should be which kind of aliphatic acid? there is not answer at 1: 1: 1.If indefinite explanation is easy to be misinterpreted as three kinds of aliphatic acid and respectively accounts for 1/3rd.The Nutrition Work person who has does not consider total fat intake, only instructs some pilot project with rule of three; The designer of the oily patent of many mediations instructs patent research with this ratio: whole design process namely loses the analysis to the fat intake total amount, also without control measure.Even have and not consider in the design of other plant ready-mixed oil whether saturated fatty acid meets 1: 1: 1 and also can be regarded as defective, and visible misunderstanding is dark; Some grease production enterprise publicizes the misunderstanding of especially directly having deepened the public at 1: 1: 1 with quoting a remark out of its context.Even so, mentioning at 1: 1: 1 o'clock, even total this prerequisite of fat intake of having emphasized, this ratio also can only be applicable to some people, and be the small part crowd.In fact, Chinese Soclety of Nutrition's authority " DRIs " has just been mentioned this saying during the suggestion of narration various countries in about intake one chapter of fat, and in the formal recommendation suggestion except n6: the n3, do not see with the form of all kinds of aliphatic acid ratios statement aliphatic acid intake.Domestic many in the industry authority, rigorous scholars all pay close attention to when mentioning this ratio and add a restrictive prerequisite in its front: " fatty energy Ratios 20～30% ", internal authority mechanism does not see independently 1: 1: 1 formulation about the deliverance of fat intake in recent years yet.Codex Committee on Food's the 32 session that report, the World Food Programme and the World Health Organization of the World Food Programme's joint specialist consulting group diet nutritional in 2002 and chronic disease holds in July, 2009 all is that the ratio that directly accounts for gross energy with all kinds of fatty energy represents to the suggestion suggestion of dietary fat.Even calculate all kinds of fatty acid proportions, these suggestions also were very different with 1: 1: 1.In addition, the formulation of ratio is that the general three large fatty acid proportions of emphasizing also make the people ignore the ratio of n6 and n3 easily, and this ratio is very important to the effect of health.

Which angle in sum, no matter to consider an out-of-date and expression form that very easily mislead the public should not become the authoritative opinion that instructs the Chinese residents fatty diet from.

Along with the development of science and technology, people have recognized gradually that excessive polyunsaturated fatty acid can work the mischief to human body.And monounsaturated fatty acids is close with the polyunsaturated fatty acid effect in the effect that reduces cholesterolemia, triglycerides, low-density lipoprotein, does not but have its disadvantage, should increase by a relatively large margin the proportion of monounsaturated fatty acids.Again, the saturated fatty acid energy ratio that accounts for gross energy 10% also has necessity of suitably turning down.Following table gathered have in recent years authority, representational part expert (country, mechanism) is about recommendation, the suggestion suggestion of all kinds of fat intakes of human body.Table 3

Some investigation and analysis that synthesise various suggestion and the scientific experiment (table 4) of being correlated with and combination are done voluntarily, the present invention proposes following main design goal and parameter:

Saturated fatty acid: the ratio that the saturated fatty acid energy accounts for gross energy is not design focal point of the present invention.The general content of the saturated fatty acid of vegetable oil is not high.Aspect the raw material selection, only otherwise adopt saturated fatty acid more coconut oil, palm wet goods minority kind, use less peanut oil, the slightly high kind of rice bran wet goods saturated fatty acid ratio example as far as possible, need not take other special measures.

Monounsaturated fatty acids: monounsaturated fatty acids does not but possess the disadvantage of the easy oxidation of polyunsaturated fatty acid to the similar polyunsaturated fatty acid in the favourable aspect of human body.So reducing as far as possible saturated fatty acid proportion, and after making the polyunsaturated fatty acid ratio reach designing requirement, remainder can all be monounsaturated fatty acids.The proportion of monounsaturated fatty acids in ready-mixed oil of the present invention is not established the upper limit.

Polyunsaturated fatty acid: the polyunsaturated fatty acid energy accounts for ratio and the n6 of gross energy: n3 ratio is the design focal point of ready-mixed oil of the present invention, also is the core design parameter.Mainly be to have considered that comprehensively human body improves blood fat, raising or do not reduce immunity, avoids lipid peroxidation and improve leukotrienes to the requirement of EPA, DHA transformation efficiency and the outside aspect such as have dinner.Its design procedure is:

＜1〉determine food polyunsaturated fatty acid absorption area gap radix:

The main object that it is balance that the food polyunsaturated fatty acid is taken in quantity, correct the incorrect picked-up of body fat acid also is one of main design considerations of ready-mixed oil fatty acid proportion simultaneously.Although have certain difficulty by all kinds of aliphatic acid quantity of food intake every day in the Accurate Determining daily life, we can make a rough estimated range to all kinds of aliphatic acid by food variety, frequency and the quantity of ingesting.On the basis of investigation and analysis and with reference to related documents, determine that following parameter is Reference Design radix of the present invention: Chinese residents average every day of normal meals custom, the polyunsaturated fatty acid quantitative range by the food intake beyond the edible oil was: in n6 series 3～15 grams, n3 series 0.5～4.5 gram, the normal meals situation, the polyunsaturated fatty acid quantity maximum of absorbing the food beyond edible oil is about 17.5 grams.

＜2〉determine the total intake radix of whole polyunsaturated fatty acids:

The total intake of the whole polyunsaturated fatty acids of normal meals structure is take gross energy 4.5% as lower limit.(refer to all eat the diet structure of edible oil of the present invention) take gross energy about 10% as the upper limit generally speaking; except edible oil of the present invention also in the situation of the edible oil of edible other kinds; on the basis that enough antioxidant protection are arranged, on be limited to about 11%.

＜3〉determine the n6 that whole polyunsaturated fatty acids are suitable: n3 ratio:

Polyunsaturated fatty acid n6: n3 ratio has significant impact to health, also is the each side maximum parameter of having different views: prevailing view thinks which kind of polyunsaturated fatty acid is too much or very fewly all can produce ill-effect to human body; The view was also expressed that the two ratio can make suitably that DHA reaches highest level and avoids producing any obvious shortage symptom in the in-vivo tissue, whether ratio is improper produces bad physiological role waits further research.Although opinion is also not quite identical, all suggestion has all been emphasized n6: the importance of n3 proper proportion.Concrete ratio aspect, each side's suggestion also has larger difference.Maximum is 10: 1, and minimum of a value is 1: 1.Wherein the average ichthyophagy quantity of resident at most the Japan of (be equivalent to food EPA, the DHA food ration is also maximum) be that once to propose 2.3: 1, Chinese Soclety of Nutrition's recommendation be adult 4～6 for 4: 1, the U.S.: 1, old people is 4: 1, and the grain farmer of the United Nations, health organization (FAO, WHO) once recommended 5～10: 1.The present invention is with reference to various countries, international organization, expert opinion, particularly selective analysis relevant animal experiment achievement in research, consider and improve blood fat, raising (being to reduce at least) body immunity, avoid lipid peroxidation and improve in the human body leukotrienes as far as possible and therefrom find out n6: the n3 optimum ratio to targets such as EPA, DHA transformation efficiencies.In conjunction with the daily diet structure of Chinese residents, determine that human body polyunsaturated fatty acid of the present invention always takes in the theoretical ratio scope of design of n6: n3: single edible oil crowd n6: the n3 design object is 2.0～5.0: 1, and mixing edible oil crowd design object is 2.0～10: 1.Single edible oil refers to only a kind of edible oil of edible the present invention, and its ratio range has been contained most of zone of Chinese Soclety of Nutrition's recommendation 4～6: 1, also is lower than 6 but minimum of a value is lower than minimum 4, the maximum of Chinese Soclety of Nutrition's suggestion, according to as follows:

" 1 " theoretical foundation: the n3 polyunsaturated fatty acid is the concept of a series.Chinese residents eats in the higher food of frequency (comprising edible oil), and the n3 polyunsaturated fatty acid that has important biomolecule to learn meaning mainly contains 18 carbon, three diluted acids (alpha-linolenic acid, ALA), eicosapentaenoic acid (EPA), 22 carbon, six diluted acids (DHA) etc.Comprise that human animal is converted into EPA, DHA in vivo by the picked-up alpha-linolenic acid, also can directly ingest and contain the food of EPA, DHA.Although these three kinds of aliphatic acid belong to n3 series together, the effect of performance has very large difference in animal body, and positive, negative effect is not always the case.Effect that it is generally acknowledged EPA, DHA is several times to tens times of ALA, and wherein the effect of DHA is more powerful.ALA is converted in vivo the efficient of DHA, EPA and only has a few percent to percent tens.In the animal experiment, n6: n3 surpasses 5: 1 o'clock transformation efficiencies and descends gradually, surpasses at 10: 1 o'clock and almost can not transform.This relation also can reasonably be explained by ALA conversion process in vivo: leukotrienes needs to prolong through a series of desaturation, c-terminus in vivo, successively is converted into eicosapentaenoic acid, 22 carbon, six diluted acids.Share identical desaturase, elongase enzyme and transacetylase in n6 and the synthetic conversion process of n3 in human body, generate eicosanoid series and all need cyclooxygenase and LOX, so n6 and n3 exist competitive relation between the two aspect metabolism.Although various enzymes are stronger to the affinity of n3, the existence of competition has affected the transformation efficiency of alpha-linolenic acid.Particularly to be converted into the approach of DHA more complicated for EPA: need to be through twice prolongation, a desaturation, beta-oxidation reaction.In this sense, ALA is that " raw material ", EPA are " semi-finished product ", and DHA is only final " finished product ".The effect of raw material is less than semi-finished product naturally, and more less than finished product, the n3 in the vegetable oil only has ALA, thereby the quantity that needs is also more.The competition that the link that transforms is many, process is complicated, the time is long and exist all the time n6 is the principal element that affects the ALA transformation efficiency.

" 2 " relevant scientific experiment supports that n6: n3 hangs down ratio: following is several relevant scientific experiment synthesis tables 4

Brief summary: 1.. accounting for n3 series proportion at EPA, DHA is under 91%～97.7% condition, and n6: n3 is that 1 o'clock immunity, Lipid peroxidation index are not good.This experimental condition is converted to the Chinese residents diet structure, and be equivalent to directly ingest for each person every day EPA, DHA reach more than 12 grams, need the ocean fish of edible EPA, DHA moderate content more than 1.5 kilograms (with the conversion of 2002 composition table of foods).As calculating that with several actual dietary survey results edible marine product must reach more than 8 kilograms.Such eating patterns should belong to special case or accidental behavior.Vegetable oil does not contain EPA, DHA, with regard to the ready-mixed oil design, is to adjust n6, n3 ratio with linoleic acid, alpha-linolenic acid.EPA, DHA can not be produced the ratio that the quantity of immunosuppressive action and lipid peroxidation directly is equal to alpha-linolenic acid.The experimental result that EPA, DHA account for n3 series 59% is n6: the suitable ratio of n3 is 1～5: 1, is converted to the meals behavior, and being equivalent to per capita, ichthyophagy every day quantity is not more than 950 grams.The maximum Areas in Shanghai City resident average per capita consumptions of sea (water) product quantity such as Chinese residents picked-up fishes and shrimps only had for the 148.5 gram/day for human beings.Even consider some special hobby, with 950 grams greatly different gap is arranged also.2.. the intake of antioxidant also is to affect the total intake of polyunsaturated fatty acid and n6: the key factor of n3 ratio.Test shows: when the content of every hectogram edible oil vitamin E reached 300mg, n6: n3 ratio equaled 1, and also can receive better effects when EPA, DHA large percentage.Ready-mixed oil of the present invention has been paid attention to the addition of vitamin E, (is equivalent to reduce n6: n3 ratio) created condition for improving n3 content.But then, the short oxygen effect that too much vitamin E easily produces in the grease can take measures to be avoided in the scientific experiment of special project.As daily edible commodity, from producing to edible, certain storage cycle is inevitable, and condition of storage also is difficult for accomplishing very perfect, protects low n6 with too much VE addition: it is very careful that n3 ratio still needs.

In sum, should be the numerical value that certain elastic range is arranged for the suitable ratio of human body n6: n3: fewer to the requirement of ALA as EPA in the food fat acid, when DHA proportion is larger, thereby n6: n3 ratio should be larger accordingly.When EPA, DHA proportion hour, need more ALA to participate in " conversion " and reach " competition ", n6: the n3 value also should be smaller accordingly.Different meals conditions should have different suitable ratio, and wherein DHA picked-up quantity is larger on the impact of suitable ratio.This is the larger major reason of the suitable ratio difference distance of the n6 that the expert of each side and mechanism are recommended: n3, and also be n6 of the present invention: n3 ratio is lower than one of important evidence of Chinese Soclety of Nutrition's recommendation.

" 3 " in conjunction with the present diet structure of Chinese residents, should increase n3 series fatty acid picked-up quantity.The fat intake official investigation that CDC carried out in 2000 studies show that: " not finding EPA and DHA composition in the meals sample ".Although this investigation result has some problems to need further to analyze, the scope of this investigation relates to 12 provinces, autonomous regions and municipalities (southern and northern each six provinces and regions).So the investigation of wide scope result illustrates that at least directly the ingest level of EPA and DHA of China resident is suitable low, and traditional storage, transportation and food processing cooking method have larger destruction to EPA in the food and DHA.Other sample investigations of carrying out later on (2 prefecture-level cities, 3 county-level cities) result shows: higher and marine product is relatively cheap, coastal prefecture-level city easily in income, EPA, DHA that the pregnant woman that diet is comparatively paid attention to takes in average every day are respectively 115mg, 181mg, are equivalent to 0.11% of gross energy.The intake in coastal cities at county level only has 55.9mg, 55.3mg, be equivalent to gross energy 0.04%, the pregnant woman on interior ground is low to moderate 11.3mg, 11.8mg especially.In the dietary survey of most economically developed coastal area Shanghai high school students, EPA, DHA amount to intake and only have 40mg every days.So less for EPA, DHA intake, and the national conditions that can not have essence to change within short-term, suitably reduce edible oil n6: n3 ratio is conducive to that leukotrienes transforms to EPA, DHA in the human body, and can therefore not have a negative impact to human body.

" 4 " Japan eats the many countries of fish quantity, its n6 in the world: even n3 ratio only has 4: 1, Chinese residents is eaten fish quantity far below Japan, and corresponding n6: n3 ratio also should be lower than the recommendation of Japan; 1992 one by having of can supporting of British funds Committee of Experts's co-present that the various countries scholar participates in the report recommends of one piece of dietary fatty acid assignment problem: EPA+DHA accounts for 0.5% of gross energy, n6: n3 ratio is 4 ".By the conversion of Chinese residents diet structure, 0.5% gross energy is equivalent to EPA, DHA daily intake 1.33 grams.Remove EPA, DHA (according to the average intake of Chinese Urban Residents, the pressing 130mg) valuation that the aquatic products of ingesting directly obtain, other 1.2 grams derive from LAL conversion in vivo.Even average conversion efficiency reaches 10%, also need 12 gram leukotrienes.The average efficiency that leukotrienes transforms in human body is far below 10%, and the leukotrienes intake that needs should be greater than 12 grams.Such diet structure is generally calculated, total n6: n3 ratio will be lower than 1.5: 1.So with n6: it is 2.0 fully no problem that n3 ratio minimum of a value is decided to be.As a same reason, suitable n6: the n3 maximum ratio also should decrease accordingly.

" 5 " the total trend of modern diet structure is towards the increasing future development of polyunsaturated fatty acid n6 series components, needs to take in more n3 series fatty acid to keep balance.

" 6 " nutrition circle a kind of saying that there's a widespread conviction that can be used as and support to reduce n6: the evidence of n3 ratio: " by inference before more than 100 year the n6 polyunsaturated fatty acid in the human diet only a little more than the n3 polyunsaturated fatty acid." from evolutional angle analysis, over one hundred year only is in a flash in the very long process of human evolution's development, that human body more adapts to should be n6: the n3 low ratio.

" 7 " its overall n6 that takes in of the resident in the more linseed oil of some edible higher proportion leukotrienes edible oil chances of China, perilla herb oil producing region, n3 ratio is far below 4 even may be lower than 1, but does not see the negative report of epidemiology survey conclusions.

" 8 " the interior ALA of child, the elderly and some Disease body is converted to the inefficiency of EPA, DHA, should suitably take into account.

" 9 " the present invention is to n6: the valuation of the minimum ratio of n3 only is in order to calculate adaptability under the extreme condition and in theory a kind of hypothesis, food n6 in the Chinese residents real life: it is very rare that n3 ratio is lower than 3: 1 diet structure.Backward is considered again, even the lower diet structure of ratio occurs, the Almightiness type combination that III type of the present invention and I type and III type form also can well adapt to.

4. calculating parameter and the formula of ready-mixed oil polyunsaturated fatty acid ratio of the present invention:

Determined above every basic parameter, by in a large number, repeatedly measuring and calculating, obtain a series of polyunsaturated fatty acid computational constant and computing formula: wherein fixed constant has four, is respectively: 5,1.07,1.6,1.27; Change the scope 0～0.94 of constant N,

Ready-mixed oil polyunsaturated fatty acid ratio computing formula:

Linoleic acid (n6) ratio=n6 coefficient ÷ edible oil quantity * 100%; Formula 1.

Alpha linolenic acid (n3) ratio=n3 coefficient I ÷ edible oil quantity * 100%+n6 ratio (%) ÷ n3 coefficient II ... formula 2.

N6 coefficient=5+1.27 * N ... formula 3.

N3 coefficient I=1.07-1.27 * N ... formula 4.

N3 coefficient II=1.6+1.27 * N ... formula 5.

Choose corresponding N value according to different meals characteristics (type), with its substitution formula 3.～5., obtain respectively the n6 coefficient, n3 is I, n3 coefficient II.Then 1., 2. each coefficient and edible oil quantity typical value substitution formula are namely obtained respectively a series of ready-mixed oil linoleic acid, leukotrienes ratio.

The selection principle that changes constant N value is: for the crowd who obviously absorbs more n3 by in addition food of edible oil (comprise outside have dinner edible oil), need to reduce the n3 intake, need accordingly to increase edible oil n6: n3 ratio, this moment, the numerical value of N also should increase (close to 0.94).Otherwise, by the less crowd of food intake n3, needing to increase the n3 composition in the edible oil, edible oil n6: n3 ratio should reduce, and the numerical value of N also should reduce (close to 0).0～0.94 can be unlimited a plurality of numerical value, corresponding obtaining without array n6, n3 coefficient I, II in theory.In the practical application, the N value can be reduced to three numerical value: for getting maximum 0.94 from food or the outside III type diet structure crowd who obtains obvious more n3 series fatty acid that has dinner.Take edible edible oil of the present invention as main II type crowd, the N value gets 0.35～0.45; Whole meals types except the III type (being the I type) all N value applicatory are 0.Exist a large amount of transiens in the practical experience of life.The corresponding set product specification of each N value is set a N value more, will increase some product specifications accordingly.Before the market demand did not form, the too much difficulty of bringing of specification was difficult for overcoming, and is unfavorable for of the present invention applying of primary stage.So the polyunsaturated fatty acid ratio that has calculated when having taken into full account N=0 when design will possess the most widely adaptability, can take into account the crowd of various different meals.

The III type of N=0.94 also has important effect: although the scope that III type itself adapts to is not extensive, the III type can be whole specifications of other numerical value with I type preparation N value.(concrete preparation way, computing formula and configuration proportion see the chapter 4 first segment for details) and along with the variation of objective condition and calculate the required data of each domestic food content of fatty acid and other conditions constantly perfect, the ready-mixed oil of corresponding polyunsaturated fatty acid ratio when releasing at any time the N value for other numerical value according to the market demand.

In the actual life, all kinsfolk's three meals in a day are all edible not general by the situation of the own cooking dish of family.Part member, part meal are finished very common beyond family.And restaurant, dining room and family can not be in full accord aspect the edible oil kind.Through to the measuring and calculating with eight kinds such as the relatively high rapeseed oil of oily frequency of utilization, soybean oil, palm oil, peanut oil, corn oil, sunflower oil, rice bran oil, ready-mixed oils (S: M: P equals 0.27: 1: 1) of restaurant, dining room, this diet structure in most of the cases can make the polyunsaturated fatty acid total amount of just trencherman's absorption increase, and n6: n3 ratio also has larger variation, and this diet structure can't be avoided.Through measuring and calculating, the standing specification of I type and other specifications of preparing, better compatible although some index is not to be in optimum state, can substantially satisfy every designing requirement.

Formula calculates the process of polyunsaturated fatty acid ratio: with N=0, N=0.94 difference substitution formula 3., 4., 5., obtaining respectively the n6 coefficient is 5,6.19; N3 coefficient I is 1.07 ,-0.12; N3 coefficient II is 1.6,2.79; 1., 2. each coefficient and each edible oil quantity typical value or edible oil quantity median substitution public affairs can be obtained I, the standing specification of III type ready-mixed oil and the specification of all categories of different polyunsaturated fatty acid ratios.

I, the standing specification of the III type ready-mixed oil (table 5 of edible oil quantity-Ke)

The specification that II type and other edible oil quantity, other N values are suited all can be formulated by a certain percentage by I, the standing specification of III type.

Edible oil classification method: take N=0 as example, with edible oil classification median substitution formula table 6

5. ready-mixed oil content of vitamin E and computing formula:

Although rare in the pathogenic case of TD, the effect of vitamin E is not limited in this.Play the anti-oxidant needs of certain health-care effect, particularly body, human body should guarantee certain intake.The vitamin E intake (AI) that Chinese Soclety of Nutrition was recommended in 2000 is 14mg α-TE/d.According to the Chinese residents eating patterns, the VE total amount is amounted to α-TE coefficient and is about 30mg by 0.45 estimation.Following factor has been considered in based on this ready-mixed oil content of vitamin E of the present invention design synthesis:

(1) Chinese Soclety of Nutrition recommend vitamin E (AI) intake be every day the foundation of 14 α-TE be: 1. this recommended amounts is about as much as on average absorption level of national resident.From the epidemiology survey angle, the TD symptom does not occur in this level.2. Chinese Soclety of Nutrition determines that the important evidence of vitamin E (AI) intake is to have taken into full account Chinese residents because containing more polyunsaturated fatty acid to the anti-oxidant factor that have more needs in the edible vegetable oil.Calculate by intake, the polyunsaturated fatty acid total amount that ready-mixed oil eater of the present invention takes in is significantly less than the average intake of Chinese residents polyunsaturated fatty acid.Thereby the requirement of definite vitamin E 90% is that 12.6mg α-TE/d is as minimum intake standard with (AI).

(2) 2002 investigation show: Chinese Urban Residents accounts for 43% of total amount by the vitamin E of the food intake beyond the edible oil, and quantity is about 6mg α-TE/d.By analysis, its wide material sources, dispersion and relatively stable.Be that 4.8mg α-TE/d is as food source of vitamin E minimum with 80% of average magnitude.The VE quantity that requires accordingly edible oil to provide is not less than 7.8mg α-TE/d.

(3) the rational ratio of vitamin E and polyunsaturated fatty acid is 0.6～0.8mg: 1 gram, but the polyunsaturated fatty acid entire quantity that human body is taken in all must be included.(authority of edible oil production aspect even national standard and ready-mixed oil designer usually only consider edible oil source and ignore polyunsaturated fatty acid in the food)

(4) α-TE is take the antisterility biologically active as criterion calculation, rather than the appropriate index of reflection tocopherol antioxidation activity.From the anti-oxidation function analysis, the power of all types of tocopherol effects and antisterility activity have the difference of great disparity.Tocotrienol particularly, its physiologically active only is 1/3rd of tocopherol, antioxidation activity then is tens times of tocopherol.

(5) antioxidant of content overrich can produce short oxygen phenomenon, and the vitamin E of different cultivars begins to occur short oxygen phenomenon in grease concentration also has very large difference: the easiest short oxygen of excessive alpha tocopherol wherein, γ, δ and tocotrienol are difficult for short oxygen.The mixed type vitamin E is because alpha tocopherol proportion is less, thereby the content that reaches short oxygen will exceed much than single alpha tocopherol.

(6) experiment showed, that the vitamin E intake reaches (AI) 50 times, can not find any toxic and side effect yet even have." the Chinese residents diet nutrient is with reference to intake " can tolerate the highest absorption value (UI) and be 800mg α-TE/d.This characteristic can make the ready-mixed oil vitamin E that the leeway of larger increase addition is arranged on the basis that does not produce short oxygen.

(7) prepare the chance that other specifications have increased Oxidation of Fat and Oils with standing specification, need the corresponding antioxidant quantity that increases.

(8) rising with dosage reduces human body to the absorptivity of vitamin E, and too high addition can cause meaningless waste.

Comprehensive above factor, the ready-mixed oil vitamin E kind of the present invention's design adopts mixed type (slipping out thing content as standard take soybean)

Hectogram edible oil content of vitamin E mg=2500/ edible oil quantity (gram)+edible oil quantity (gram) * 0.4; Formula 6. 1. content of vitamin E comprise original part, be lower than original content such as formula result of calculation, then keep former content; Edible oil quantity is minimum edible oil quantity of all categories when 2. calculating take the classification method; 3. for guaranteeing intake, the whole carries of decimal are integer;

Standing specification method content of vitamin E table 7

(2) adaptability and security

1. about the relevant issues with the extremum measuring and calculating: scale 9 is taken in the food fat acid with extreme mode valuation

Another guiding theory of the every design object setting of the present invention is: nutrition field mean value commonly used should not be as the sole criterion of individual products Performance Detection.With regard to individual, first hyperphagia and second are ingested not enough in relation.In order to make this product can adapt to the crowd of various diet structures, every main design goal is all calculated through extremum.As its name suggests, the valuation in extreme mode is called for short extremum.Its concrete meaning is: in the food there be than big difference all kinds of content of fatty acid.In order to guarantee that product of the present invention can have the most widely adaptability, measuring and calculating n6: during the n3 maximum, various kinds of foods is all selected also larger kind of the maximum and content absolute value of ratio; Measuring and calculating n6: during the n3 minimum of a value, various kinds of foods is all selected the kind of ratio minimum; Measuring and calculating food polyunsaturated fatty acid principle maximum, minimum of a value also is to select respectively the maximum or minimum kind of content of polyunsaturated fatty acid.Extremum also has an important feature to be: suppose all edible identical food of each meal, and such dietary has exceeded normal range (NR).In fact, the principle of this selection kind is theoretic a kind of measuring and calculating way.Its objective is: the difficulty of correcting the incorrect picked-up of food fat acid when strengthening measuring and calculating as far as possible with ready-mixed oil aliphatic acid of the present invention.For the setting that exceeds normal meals scope extremum, except above theoretical calculation, the present invention is also with reference to the crowd of intolerance style diet structure probability of occurrence maximum---the pregnant woman of different regions and the developed regions children's that the partial eclipse phenomenon appears in most probable diet structure.And further leave again on this basis certain leeway.

(1) about food n6: the n3 maximum:

Although the n6 of some crowd's eating patterns: n3 ratio may surpass the extremum 30: 1 that the present invention arranges, as long as but the polyunsaturated fatty acid total amount of its absorption is not more than extremum sum 15.5 grams (15 restrain n6 and 0.5 gram n3 sum), will be less than the difficulty of correcting the extremum setting with the difficulty that ready-mixed oil of the present invention is corrected.For example: food n6, n3 intake are respectively 10 grams, 0.2 gram, and n6: although n3 ratio reaches 50, edible oil, the total n6 of food: the n3 maximum is close to the design standard value by 4.4, reduces to 3.5.The problem that this desired value need to be considered mainly is in the situation of n6 series picked-up total amount 15 grams, and whether n3 series intake 0.5 gram is enough low.In the higher food of the daily edible frequency of Chinese residents, contain the food of a greater number n3 series fatty acid such as bean product, beans; Each the breeding stock meat, poultry, egg, the newborn class that contain certain n3 quantity; Although some food n3 content is few, belong to the kind that all must eat every day, such as grain; Also have some common food of not lising at the fatty acid composition table, also all contain some alpha linolenic acids such as bottle green vegetables etc.; The EPA that contains in the fresh-water fishes of some kinds, DHA even be higher than some marine product.To take in 0.5 gram n3 series polyunsaturated fatty acid every day should be reliable as minimum flow.Even some special population reaches gram every days 15 in n6 series intake, n3 series fatty acid intake is lower than 0.5 gram simultaneously because minimum intake radix (0.5 gram) is very little, total on n6: the impact of n3 ratio is also very limited.

(2) about food n6: the n3 minimum of a value:

Whether the setting of this desired value is reliable, and the problem of need considering mainly is: whether n3 series intake 4.5 grams enough many and food n6: n3 ratio is 2.9: 1 no enough low.Just the sour composition of at present known food fat (reaching relevant paper, document with reference to composition table of foods) hectogram food n3 series content surpasses 30 kinds of 1 inanitions that restrains, even wherein frequent edible kind only has nut and the higher marine product of part bean product n3 content also to only have the minority kinds such as mackerel, oil are expressed, anchovy.The crowd of a large amount of edible nuts is not within the scope of the invention.All the other two based foods total amount of ingesting every day will reach 400～500 grams, and the n3 of its picked-up just might reach 4～5 grams, and every meal all eats same food.By present meals condition and dietary, Chinese residents only restrains above n3 by food intake 4.5, and makes n6: n3 ratio drops to below 3: 1 uncommon.

(3) about the peaked security of EPA, DHA picked-up total amount:

Have the Committee of Experts to propose in a specialized conference of Britain: the safe range of taking in EPA and DHA sum maximum is gross energy 2%.By the standard conversion of Chinese residents, gross energy 2% approximates 5.33 gram fat, and the ocean fish that is equivalent to DHA, EPA moderate content will eat 750 grams every day.This advises matching with relevant results of animal.In the traditional eating patterns of (also have research points out to only have DHA, EPA intake reach 20～25 grams and just can produce immunity performance) Chinese residents, the fish and shrimp intake is in low especially level.Chinese Soclety of Nutrition's Diet pagoda is every solar eclipse 50 grams to the recommended amounts of fishes and shrimps, and 2002 investigation results are per capita solar eclipse fish and shrimp 25.6 grams of the whole nation, even the high receipts crowd in big city, daily diet also only has 82.3 grams per capita.Even consider the factor of future economy high speed development, the level of the edible marine product of national resident all reaches 148.5 grams of Areas in Shanghai City, and average daily 750 gram sea (water) products also are a quantity that is difficult for being exceeded.Backward is considered again, for the normal meals structure, even the series of the n3 in the food fat acid is DHA, EPA all, accounts for TFA n3 series and at most also only has about 50%, and its absolute intake also only has several grams, and remainder is the alpha linolenic acid in the ready-mixed oil.Leukotrienes is converted into the average efficiency less than 10% of DHA, EPA in vivo, and enough securities should be arranged.

(4) about food polyunsaturated fatty acid total amount maximum:

" 1 ". according to measuring and calculating, the polyunsaturated fatty acid that Chinese residents is absorbed from food on average is about about everyone gram every days 8～10.The present invention is made as 17.5 grams with maximum, is about 1.8～2.2 times of average magnitude.This maximum can not be broken generally speaking.

" 2 " verify composition table of foods, through measuring and calculating, the food polyunsaturated fatty acid that edible frequency is higher accounts for all fatty acids average proportions and is about about 25%.In the conversion of this ratio, daily absorb the food fat that polyunsaturated fatty acid 17.5 grams are equivalent to every daily ingestion and be about 73.3 grams, be about 1.6 times of national big city resident's average level.Be converted to fatty energy Ratios and surpass 50% (the edible oil intake is with average), can cover the crowd of most normal meals customs.

" 3 " consider from oxidation resistant physiological requirements aspect: it is generally acknowledged that reasonably the ratio of vitamin E and polyunsaturated fatty acid should be not less than 0.6～0.8mg: 1 gram.Press mixing vitamin E and calculate, vitamin E of the present invention is 1mg with the minimum ratio of whole polyunsaturated fatty acids (comprising edible oil): 1 restrains, and approximates 1.67 times of minimum standard.The minimum intake of total vitamin E is 30 milligrams (mixing) if by anti-oxidant standard VE: PUFA equals 0.6～0.8mg: 1 gram measuring and calculating, the polyunsaturated fatty acid quantity that the minimum intake of vitamin E can be protected reaches 37.5～50 and restrains.Be converted to whole fat by Chinese residents food fat acid average content; total amount will be at 150～200 grams; be equivalent to fatty energy Ratios 55%～70%; even this result has illustrated that from another angle its polyunsaturated fatty acid picked-up total amount of special diet custom crowd surpasses 17.5 grams; also have enough vitamin Es and give and protection, the problems such as lipid peroxidation and Immunosuppression power can not occur because polyunsaturated fatty acid is excessive.

" 4 " crowd of higher fatty acid absorption generally also is high-energy absorption person.Do not take into full account the normal man in the measuring and calculating and convert factor.1.2 times of measuring and calculating radixes as the maximum intake of polyunsaturated fatty acid with average energy in fact also are equivalent to leave certain leeway.

(5) the minimum intake design load of food polyunsaturated fatty acid is 3.5 grams, and main consideration adapts to the vegetarian.For such crowd, the polyunsaturated fatty acid that only obtains from edible oil surpasses 3%, reaches the minimum standard that the nutritionist requires.Food polyunsaturated fatty acid energy valuation 1.5% should be very low level, as measurement index is close to ideal value when being higher than 1.5%.The accuracy of minimum gross energy intake radix is unimportant in this case.

(6) standing specification method I type ready-mixed oil without outside have dinner, food fat acid intake with extreme mode valuation situation under the measuring and calculating information slip 10 of main design goal

(7) the outside detailed measuring and calculating of main design goal value in the more situation of having dinner: the Chinese residents dietary is three meals in a day, breakfast dish is simple, oily quantity for cooking seldom, during (account for about 5% of edible oil on the one, even still less) edible oil intake concentrates on substantially, dinner.The outside polyunsaturated fatty acid of having dinner is taken in total amount and n6: n3 ratio will all be in breakfast, lunch and dinner (edible ready-mixed oil of the present invention) differ widely, and this phenomenon is inevitable.Except the elderly and children, working day Chinese meal substantially outside, the dinner situation of substantially being in once in a while outside is the most common.With oil product kind aspect, except high-grade used by hotels and restaurants by oil for cooking uses olive oil, tea oil, dining room, various places, restaurant with oily maximum be rapeseed oil, soybean oil, peanut oil, palm oil and sunflower oil, corn oil, rice bran oil and ready-mixed oil (S: M: P equals 0.27: 1: 1) etc.In factors, on the larger factor of fatty acid uptake amount impact be successively: edible oil kind, outside have dinner number of times, outside edible oil picked-up quantity.Have dinner edible oil kind and the number of times of having dinner of outside is difficult for voluntarily control, can control to a certain extent but absorb edible oil quantity at every turn.Every meal is taken at most edible oil 15 gram when having dinner such as the outside, have dinner and (be equivalent to the legal workday Chinese meal all outside in maximum 25 situations in the outside per month, dinner is once in a while outside) measuring and calculating polyunsaturated fatty acid ceiling capacity ratio: corn oil, soybean oil, sunflower oil are 10.5～10.9%, and other kinds are all in 10%.N6: n3 maximum ratio: peanut oil, corn oil, sunflower oil 7.6～8.3, soybean oil, rice bran oil, palm oil 6.4～6.8, rapeseed oil, ready-mixed oil 5.2～6.0; N6: the n3 minimum ratio is all within 2.1～3.3 scopes.The polyunsaturated fatty acid ceiling capacity of some kinds is n6 when: although the maximum ratio of n3 has surpassed the ideal value of the present invention's design, all within the acceptable scope.Moreover this only is the results of measuring under the extremum condition.

Below for the ready-mixed oil of one group of polyunsaturated fatty acid ratio of I type of the present invention (N=0) the more outside main design objective measuring and calculating information slip 11 in the situation of having dinner is being arranged

The restaurant is in order to pursue taste and outward appearance, and generally all excess is used oily.For health, strong suggestion reduces the outside number of times of having dinner as far as possible, and also will reduce the edible oil in the direct absorption dish during outside eating as far as possible.(for example give up the soup juice that contains Chuck Steak and avoid consuming oil deep-fried food and the too much food of oil-containing) otherwise no matter from that angle, too much absorption fat, particularly excessive saturated fatty acid, polyunsaturated fatty acid are all with severe damaging body health.And the n6 of the rational total intake of polyunsaturated fatty acid and relative ideal: n3 ratio also can't guarantee.In addition, also will note avoiding oil for cooking when selecting the restaurant is the higher kind of polyunsaturated fatty acid ratio as far as possible, and partly eating during conditions permit and time carrying lunch also is a kind of good selection.If average each picked-up edible oil quantity reaches 20 grams, n6: n3 maximum: rice bran oil, peanut oil, corn oil, sunflower oil 7～8.9, soybean oil, palm oil 6.5～6.9, other kinds are below 6.0; N6: the n3 minimum of a value is without marked change.Polyunsaturated fatty acid energy Ratios maximum: corn oil, soybean oil, sunflower oil 11.3～11.7%, ready-mixed oil 10.6%, other kind is below 10.2%.

In addition, the outside oil for cooking of having dinner is that linseed oil, purple perilla wet goods leukotrienes are the kind of main component, although edible I type ready-mixed oil of the present invention and classification method (N=0) ready-mixed oil can be corrected the too much problem of polyunsaturated fatty acid n3 picked-up to a certain extent, but still have certain risk.Edible this class edible oil is as surpassing tens meal per month, and its n6: n3 ratio may be lower than 1 in some cases.Use linseed oil, purple perilla wet goods for local restaurant oil custom for cooking, the chance of having dinner at the restaurant is more crowd again, and have a liking for especially the fish crowd of (comprising other marine products, aquatic products) that eats, suggestion should eat the III type ready-mixed oil of N=0.94 of the present invention, and perhaps the N value is the ready-mixed oil of other numerical value.

Illustrate: every data of＜1〉table 11 all are to be not more than the conditions measuring and calculating of each 15 grams with the outside edible oil intake of having dinner.Consider from anti-oxidant aspect merely, even reach 25～30 g/timess, although externally the edible oil kind is that polyunsaturated fatty acid energy Ratios under corn oil, the sunflower oil condition may reach 12.5%～13%, vitamin E all is not less than 0.8: 1 with whole ratios of polyunsaturated fatty acids.The problem that exists is n6: maximum surpassed 10, n6 when the every meal of edible oil intake reaches 30 gram when n3 ratio was externally had dinner every meal 25 gram of edible oil intake: the n3 maximum ratio surpasses 11.The polyunsaturated fatty acid energy Ratios also significantly exceeds standard.Therefore have dinner except control meal number in the outside, and edible oil is taken in quantity in the time of also will controlling the outside by every possible means as far as possible and have dinner.

＜2〉the present invention all in the measuring and calculating maximum and minimum of a value actual be certain class crowd of hypothesis, no matter be in or the equal edible identical food of outside eating three meals in a day, and the fatty acid composition of these foods all meets again the result that specific condition (being extremum) just can occur.As long as each canteen thing changes to some extent, extreme maximum and minimum of a value all can be drawn close to the centre.

＜3〉the outside edible oil kind of having dinner: ready-mixed oil is specification (S: M: P=0.27: 1: 1) comparatively general on the market; Because the improvement of two low rapeseed oils is not yet fully universal at present, calculates with the high erucic acid rapeseed oil fatty acid proportion temporarily.As calculating by two low kinds, desired value also can make moderate progress; The aliphatic acid of other edible oil kind is with ratio measuring and calculating common in document and the data published;

(7) the edible oil quantity in the above measuring and calculating all be take one accurately numerical value as the basis.In real life, all a plurality of members can be arranged except the general family of special circumstances (unmarried).Member in the same family, although dietary is roughly the same, also can not be in full accord, the quantity that edible oil is taken in can produce a certain distance because of many reasons.So the present invention notes taking into account the same family member edible oil picked-up quantitative aspects existing gap when the design of major parameter: the edible oil intake that the edible oil quantity typical value of standing specification method can adapt to can differ 40% at most, namely take edible oil quantity typical value and by other edible oil quantity of its configuration as the basis, actual edible oil quantity increases, when subtracting 20%, main target parameter: polyunsaturated fatty acid total amount and n6: n3 ratio is all within allowed band; Classification method itself designs as the basis take the edible oil quantity gap of certain limit exactly, can adapt to the existence of this difference.

2. the adaptability of vitamin E addition and security

When＜1〉calculating vitamin E maximum ingestion quantity, one tangent condition is all can absorb maximum vitamin E settings: ready-mixed oil content of vitamin E of the present invention is higher than the existing whole kinds of commercially available edible oil, take each edible oil quantity typical value as radix, corresponding outside edible oil intake is zero; Vitamin E quantity by food intake is take 1.5 times of average national level as radix.With this results of measuring, the not enough 25mg α-TE/d of maximum VE intake only recommends reference quantity (IU) value 3.1% for Chinese Soclety of Nutrition's diet nutrient.

＜2〉during the minimum picked-up of measuring and calculating vitamin E quantity, a tangent condition is all absorb minimum vitamin E setting: average every daily ingestion edible oil amount of the present invention take each edible oil quantity typical value 55% as radix (with the inferior reckoning of the edible minimum meal of edible oil of the present invention per average daily amt); Outside edible oil quantity is each 15 grams, compares rapeseed oil, soybean oil, peanut oil, ready-mixed oil, sunflower oil, corn oil, rice bran oil, palm oil and the modal kind of salad wet goods, and the content of vitamin E of tea oil and salad oil is minimum.Through investigation and analysis, because cost is higher, this two kind cooking dish are seldom used in general restaurant, restaurant except high-grade hotel.So palm oil content that will be time low is as the Representative Cultivars of minimum.Vitamin E quantity by food intake is calculated by 80% of average national level.By universal law, seem the discount deficiency with 80% of mean value as minimum of a value.To this, the present invention did labor: the form that exists in the various foods of vitamin E beyond edible oil, paddy manufactured goods and flavouring, drinks is extensively to disperse, and is not prone to because partial eclipse causes and absorbs the larger gap of quantity.The paddy manufactured goods that the content of vitamin E gap is the most greatly different (be zero such as rice VE content) are although be the staple food of a lot of Area Inhabitants, but its source only accounts for 1.8% of vitamin E picked-up total amount, accounts for 4.2% (the national big city of 2002 investigation resident's average) of food vitamin E.According to the characteristics of vitamin E, reducing the intake factor with 20% as special diet should be enough.Under these conditions, the minimum intake of vitamin E is not less than 12.6 α-TE/d.And the minimum 4# of VE intake only is points of 20 grams, if with the preparation of other quantity, minimum intake all will improve.Also there is certain fine setting leeway according to actual conditions when preparing in addition: for the family of needs increase VE intake, can select a fairly large number of combination of edible oil.For example 40 grams can be by 4-3#, 4-2# combination, and the VE intake of 4-2# combination makes up greater than 4-3#.

＜3〉about short oxygen problem: have experiment to show: edible oil and fat add the mixed type vitamin E and are up to the 320mg/ hectogram, do not find significantly short oxygen phenomenon.Another special conclusion (of pressure testing): 10 gram polyunsaturated fatty acids contain the 83.67mg vitamin E, can reach preferably antioxidant effect.By this standard, the standing specification ready-mixed oil content of vitamin E of polyunsaturated fatty acid proportion maximum can reach the 384mg/ hectogram.The maximum level of ready-mixed oil mixed type vitamin E of the present invention only is 133 milligrams/hectogram edible oil, can not produce short oxygen problem.Below be all kinds of crowd's vitamin E picked-up information slips 12 under various extreme conditions

Four. the specific embodiment:

Different diet structure crowds are reasonable, balance is ingested all kinds of aliphatic acid and vitamin E problem in order to solve in the present invention, designed the personalized ready-mixed oil scheme of a plurality of polyunsaturated fatty acid ratios and content of vitamin E.Although can choose different N values for different meals characteristics, calculate the some groups of polyunsaturated fatty acid ratios that are suitable for different edible oil typical values and edible oil classification crowd by formula, but under present circumstances, the ready-mixed oil of one group of 4 standing specification that first-selected I type, N=0 calculate and according to market demand, on the basis of four standing specifications of I type, increase again the Almightiness type of two standing specifications of III type.When market demand and objective condition possess, can be prepared arbitrarily by Almightiness type for the transiens of N value between 0～0.94.When the N value was drawn close to 0.94 gradually, edible oil linoleic acid and leukotrienes ratio maximum can increase to 2.96, substantially can adapt to the crowd of all kinds of diet structures.Although this combination is not because the problem that the described food fat acid of chapter 2 classification faces also possesses comprehensive implementation condition in the present circumstance, but can according to circumstances partly implement at present, for example the outside number of times of having dinner is less than 25 times that the present invention sets, and the fairly obvious diet structure (meals characteristics) of some feature, the N value can be greater than zero.And along with the development of science and technology and the variation of objective circumstances, can not implement the N value between 0～0.94 after not getting rid of, edible oil quantity, food fat acid composition round Realization Extraordinary possibility.The standing specification of Almightiness type that is comprised of I, III type also is a kind of very necessary combination.

(1) embodiment:

1. the ready-mixed oil that is suited with 4 standing other edible oil quantity of specification preparation I type of I type

＜1〉family every day per capita edible oil quantity calculate: every day, edible oil quantity=edible oil consumed total quantity/∑ (each meal of each member have a dinner number of times * each meal time edible oil quantity coefficient) * each member normal man's coefficient per capita;

Certain 2 people of family for example, normal man's coefficient: first 1.2, second 1.1; 30 days edible oil quantity consumed 1900 grams.Determine each meal time edible oil quantity coefficient according to these family's meals characteristics, for example: breakfast 5%, Chinese meal 50%, dinner 45%; The number of times first of having a dinner in each member family; Breakfast 28 times, Chinese meal 7 times, dinner 27 times; Second: breakfast 30 times, Chinese meal 7 times, dinner 29 times;

Have a dinner in the family and amount to number of days: first (28 * 0.05+7 * 0.5+27 * 0.45) * 1.2=20.5 (day);

Second (30 * 0.05+7 * 0.5+29 * 0.45) * 1.1=19.9 (day);

This family every day per capita edible oil quantity=2020 grams/(20.5+19.9) day=50 grams/day;

(also can simplify above-mentioned calculating: survey the representational edible oil actual consumption of a few meal amount and convert per capita quantity consumed every day).

＜2〉suitable polyunsaturated fatty acid ratio and the content of vitamin E of this family calculates: according to formula 3., 4., 5., draw the N6 coefficient and be 5, N3 coefficient I is 1.07, N3 coefficient II be 1.6. substitution formula 1., 2., obtain target ready-mixed oil design parameter: the linoleic acid ratio: 10%, the alpha linolenic acid ratio 8.39%; 6. obtaining content of vitamin E according to formula is 70 milligrams/hectogram edible oil;

＜3〉with standing specification preparation target ready-mixed oil: four kinds of preparation combinations can be arranged: 1#-4#, 2#-4#, 1#-3#, 2#-#3.For reducing cost and alleviating purchasing of raw materials pressure, avoid the tea oil that uses the linoleic acid ratio lower as far as possible, should adopt the 2#-#3 combination.

＜4〉configuration proportion calculates: (I, III type) ready-mixed oil linoleic acid that the N value is identical in the same type: linolenic ratio is also identical.

In the target ready-mixed oil, standing specification (3#) proportion that the linoleic acid ratio is higher={ standing specification (2#) the linoleic acid ratio that target ready-mixed oil linoleic acid ratio-linoleic acid ratio is lower }/{ standing specification (2#) the linoleic acid ratio that standing specification (3#) the linoleic acid ratio that the linoleic acid ratio is higher-linoleic acid ratio is lower } ... formula 7.=(10%-9.4%)/(11.1%-9.4%)=35.29%, namely the 3# proportion 35.29%; 2# ratio=100%-35.29%=64.71%; Result of calculation: the target ready-mixed oil is comprised of the standing ready-mixed oil 64.7% of I type 2#, the standing ready-mixed oil of 3# 35.3%;

Check the preparation result: the new ready-mixed oil linoleic acid ratio of preparation=64.71% * 9.4%+35.29% * 11.1% ≈ 10%; Leukotrienes ratio=64.71% * 7.9%+35.29% * 9.3% ≈ 8.39%; Content of vitamin E=64.71% * 69+35.29% * 70.8 milligrams/hectogram of 74 ≈ edible oil; Substantially meet design object.The configuration proportion that other edible oil quantity are suited in the same model by that analogy.

2. use for convenient, with I, each parameters difference substitution formula of III type 20～60 gram edible oil quantity 7., obtain table 14, table 15.Required standing specification schedule of proportion 14 when the ready-mixed oil major parameter that each edible oil quantity of I type (N=0) is suited and preparation

Required standing specification schedule of proportion 15 when the ready-mixed oil major parameter that each edible oil quantity of III type (N=0.94) is suited and preparation

1. table 14,15 edible oil quantity are all in grams.The corresponding parameter of more accurate edible oil quantity need to be calculated separately by formula; 2. calculate with formula or edible oil content of vitamin E that the ratio that obtains of tabling look-up is prepared may be a little more than formula result of calculation 6.; 3. according to producing and manage needs, can be with other edible oil quantity and corresponding parameter as the interim or long-term standing specification of edible oil quantity typical value, but 7. the configuration proportion of table 14, table 15 must recomputate by the substitution formula.

3.N value is the parameter of reflection edible oil linoleic acid and leukotrienes ratio, but more abstract.In the practical application, ask needed ready-mixed oil N value more directly perceived, and then obtain other needed parameters with the N value with the linoleic acid of target ready-mixed oil/leukotrienes ratio.Target ready-mixed oil linoleic acid/leukotrienes=(8+8.382N+1.6129N ²)/(6.712+0.5969N-1.6129N ²); Formula 8. formula calculates more loaded down with trivial details.Different N values and edible oil linoleic acid/leukotrienes ratio table of comparisons are listed, used with convenient.Table 16

Annotate: I, III type edible oil quantity can be any numerical value in identical situation; Owing to data levels of precision reason (repeatedly quoting the accumulated error that rounds up and produce) result who tables look-up and the gap that may have with formula result of calculation by a small margin;

Take I, III type calculate (or tabling look-up) when trying to achieve N value and edible oil quantity as other numerical value corresponding ready-mixed oil major parameter step for example: edible oil quantity 40 restrains N=0.5; The substitution formula 1.～6., target ready-mixed oil major parameter: 78.5 milligrams of linoleic acid ratios 14.088%, leukotrienes ratio 7.391%, hectogram edible oil content of vitamin E;

All decimal point can keep several as much as possible in the computational process, and end product is cast out again, to reduce accumulated error.

＜1〉formula computational methods

The first step: preparing respectively I, III type edible oil quantity is the corresponding ready-mixed oils of 40 grams.

The I type: edible oil (temporarily numbering 8#) the substitution formula that edible oil quantity 40 gram is suited 1.～6. obtain:

8# parameter: linoleic acid 12.5%, leukotrienes 10.488%, content of vitamin E 78.5mg; Prepare with 3#, 4#:

4# ratio=(8# linoleic acid ratio-3# linoleic acid ratio)/(4# linoleic acid ratio-3# linoleic acid ratio);

=(12.5%-11.1%)/(25%-11.1%)=10.07%; 3# ratio=1-10.07%=89.93%;

The III type: edible oil (temporarily numbering 9#) the substitution formula that edible oil quantity 40 gram is suited 1.～6. obtain:

9# parameter: linoleic acid 15.485%, leukotrienes 5.233%, content of vitamin E 78.5mg; With 5, the 6# preparation:

6# ratio=(9# linoleic acid ratio-5# linoleic acid ratio)/(6# linoleic acid ratio-5# linoleic acid ratio)

=(15.485%-10.3%)/(31%-10.3%)=25.05%; 5# ratio=1-25.05%=74.95%;

Second step: calculate I type, III type configuration proportion:

With N=0.5 substitution formula 9.: III type (9#) ratio=(21.97N+10.13N ²)/(16.95+12.52N+N ²)=57.62%;

I type (8#) ratio=100%-57.6%=42.38%;

More than each step only be a computational process, can once finish preparation in the practical operation.Target edible oil is prepared by following specification:

3# ratio=42.38% * 89.93% ≈, 38.11% ≈ 38.1%; 4# ratio=42.38% * 10.07% ≈, 4.27% ≈ 4.3%;

5# ratio=57.62% * 74.95% ≈, 43.19% ≈ 43.2%; 6# ratio=57.62% * 25.05% ≈, 14.44% ≈ 14.4%;

Check the result: linoleic acid ratio=38.1% * 11.1%+4.3% * 25%+43.2% * 10.3%+14.4% * 31% ≈ 14.22%;

Leukotrienes ratio=38.1% * 9.3%+4.3% * 21%+43.2% * 3.5%+14.4% * 10.5% ≈ 7.47%;

81.6 milligrams of content of vitamin E=38.1% * 74+4.3% * 133+43.1% * 66+14.5% * 133 ≈;

＜2〉the look-up table first step: preparing respectively I, III type edible oil quantity is the corresponding ready-mixed oils of 40 grams:

Table look-up 14, edible oil quantity 40 grams: I type (8#) is prepared by 3#89.93%, 4#10.07%;

Table look-up 15, edible oil quantity 40 grams: III type (9#) is prepared by 5#75%, 6#25%;

Second step: the corresponding result of 17, the N=0.5 that tables look-up is III type (9#) ratio=57.62%; I type (8#) ratio=42.38%; The correlation computations of other edible oil quantity and N value by that analogy.In the practical application, with the preparation of standing specification and formula 1., 7.～9. the theoretical numerical value, the formula that 2. calculate calculate and table look-up, its result all may have a certain distance.Through measuring and calculating, worst error is about 1%.The linoleic acid of (main cause is that the standing specification of edible oil quantity can only keep a decimal) but target edible oil/leukotrienes ratio and polyunsaturated fatty acid total amount error are all less than one thousandth; VE content can omit height generally speaking, but within scope of design.

5. classification method: if I type or the specification that needs with I, the standing specification preparation of III type run into unsurmountable difficulty and can't implement the time, can release this scheme in some situation (or some zone).Concrete way is take family as unit Chinese residents 20～70 gram edible oil quantitative ranges to be divided into one group of fixing specification of each category setting of 6 class (edible oil classification), directly edible need not again the preparation.Classification method ready-mixed oil (N=0) main design parameters table 18

The practical application of classification method is given an example: (N=0) edible oil quantity 43 grams, 2,3 classifications are all applicable.With the 2nd classification median (absolute value) gap be 6 grams, with the 3rd classification median (absolute value) gap be 1.9 grams, more appropriately the 3rd classifications.

6. all kinds of vegetable oil compositions of the standing specification of I type ready-mixed oil and all fatty acids ratio embodiment table 19

For reducing cost, can reduce tea oil and linseed oil ratio as far as possible, it is raw material that part sequence number ready-mixed oil is selected Canola Oil.Specifically selecting aspect the vegetable oil raw materials, the vegetable oil that the present invention uses is lower with saturated fatty acid proportion, monounsaturated fatty acids proportion is higher, and the tea oil that linoleic acid proportion is on the low side is main.1#, 2# ready-mixed oil require linoleic acid proportion to be lower than the linoleic acid content typical value (10%) of the common kind of tea oil, should be noted and select the lower tea oil kind of linoleic acid content to make raw material.Wherein the 1# ready-mixed oil needs to be no more than 7.2% tea oil with linoleic acid proportion, and 2# needs to be no more than 8.3% tea oil with linoleic acid proportion.Other sequence numbers can adopt conventional variety as raw material.For adjusting all kinds of fatty acid proportions, also need select the n6 polyunsaturated fatty acid is higher, saturated fatty acid is lower and the content of vitamin E is relatively high corn oil, and the higher linseed oil of linolenic acid content.Vitamin E also can add an amount of tocotrienol with natural mixed type (refining slips out thing such as soybean oil: alpha tocopherol accounts for 10%, and all the other are β, δ, γ type).Although theoretically, edible can the generation of the present invention urged the oxygen problem, and its content of vitamin E is significantly higher than commercially available general kind after all, still is necessary to take some corresponding measures more.In whole embodiment, as required, can adopt other vegetable oil that meet designing requirement as raw material, such as olive oil, soybean oil, peanut oil, rice bran oil, sunflower oil, safflower oil, purple perilla wet goods to adapt to market demand.Each vegetable oil all is the product oil through refining processing, and stirring and filling process are identical with present ready-mixed oil production technology.

The problem that should be noted that also has all kinds of vegetable oil raw materials of existing market sale owing to the place of production, processing mode are different, its content of fatty acid difference is very large, with several years ago data, document (comprising that the publication of some national authority departments is such as 2002,2004 editions composition table of foods) differ widely.In addition, climatic variation also is to affect the key factor that all kinds of aliphatic acid proportions of vegetable oil change; Content of erucic acid in the rapeseed oil has reduced many than in the past, even but Canola Oil, quality is also uneven.There is report to point out that indivedual tea oil kinds also detect a small amount of erucic acid.Although at present epidemiology survey can not confirm erucic acid to the direct harm of healthy human body, promotes stage adaption object crowd's characteristics for certain class crowd (for example heart dysfunction) and the present invention, will control undoubtedly the intake of erucic acid; Trans-fatty acid is the product in the vegetable oil refining process, and the health of human body is had larger impact.Above problem all should be noted detection and takes appropriate measures when selecting the ready-mixed oil raw material.

Illustrate: 1. some parameters of I of the present invention, II, III type and classification method defined only are to provide a kind of direction of dealing with problems, principle, concrete way, computing formula and a series of approximate parameter according to current actual conditions.Because objective condition changes or market demand, N value and edible oil quantity typical value can be applied in a flexible way as required and needn't be sticked to the restriction of all types of accommodations that the present invention sets.After new N value and edible oil quantity typical value are set, can utilize formula to calculate corresponding some groups of new polyunsaturated fatty acid ratios and content of vitamin E as the new standing specification of ready-mixed oil.2. edible oil is as a kind of traditional food, and Chinese residents is generally not too noted metering link (this is a kind of bad habit that need to progressively give up certainly).Even emphasized metering, because the intrinsic characteristics (viscosity is large, surface tension is large) of edible oil also are not easy to accomplish very accurate.In the practical application, computational process accomplishes accurately particularly to relate to fatty acid proportion as far as possible.Calculate or the data that obtain of tabling look-up keep several decimals (will produce unnecessary accumulated error otherwise repeatedly round up) as much as possible according to formula, last result of calculation is the reservation figure place of disposable decision necessity as required again.There is necessarily deviation by a small margin not affect final effect in the concrete operations.(n6: n3 ratio and polyunsaturated fatty acid total amount) 3. the leukotrienes described in all files of the present invention all refers to alpha linolenic acid;

(2) problem and the prospect forecast in practicing

Although the present invention accomplishes thorough consideration and measuring and calculating in each side such as edible oil, food fat acid picked-up and vitamin Es, and makes every effort to make product that the most widely adaptability can be arranged as far as possible, in fact still to be subject to the restriction of many objective condition.The problem that mainly has at present three aspects:

1. owing to simultaneously saturated fatty acid and the polyunsaturated fatty acid ratio of edible oil limited, the primary raw material that meets design condition can only be as main tea oil, olive oil take monounsaturated fatty acids; In order to increase the alpha linolenic acid intake so that n6: n3 ratio reaches designing requirement, and linseed oil also will guarantee certain adding proportion.This is the highest several kinds of cost in the edible vegetable oil.Even without olive oil and select some qualified two low rapeseed oils as far as possible, total average unit cost also to be higher than daily other the edible edible oil kinds of resident.In addition, to the strict demand of raw material, require tea oil to select the linoleic acid ratio to be lower than common kind, rapeseed oil quality requirement such as the ready-mixed oil of part sequence number and reach two substandards, relatively accurate determination of fatty acid; Other measures as the anti-oxidant measure of the natural VE of larger addition, higher standard, be in harmonious proportion for the second time needed inner wrapping finished product, novel concept the new product publicity, the personnel of selling are carried out necessary nutrition rudimentary knowledge training etc. all is the factor that increases cost.The higher major obstacle that is likely that the primary stage of the present invention popularizes of price;

2. present national tea oil annual production is about 260,000 tons, in tea oil ratio in the ready-mixed oil of the present invention and consider that crowd's proportion weighted that each sequence number ready-mixed oil adapts to estimates per capita consumption, even all output is all for edible oil, also only reaches 2000～3,000 ten thousand people's amount.Although tea oil is in unsalablely current owing to not being familiar with by the consumer, the price of high enterprise can not significantly descend in short-term.Particularly rare quantity is to affect the latency that product of the present invention enlarges popularity;

3. product specification is more: also will surpass traditional specification quantity even only produce one group of (N=0) its product specification;

Although some problem has exceeded the academic discuss category of nutrition, conduct is to promote, to be applied as the patented product of final purpose, and relevant problem should be considered to some extent.

Recognize recently, united " the national tea oil industrial development planning (2009-2020) " of appearance by National Development and Reform Committee, the Ministry of Finance, the State Administration of Forestry and formally promulgate through State Council approved.Planning proposes: to the year two thousand twenty, national oil tea cultivated area will increase to 7,000 ten thousand mu by 4,500 ten thousand mu, and output will reach more than 250 ten thousand tons.Can find out that cultivated area enlarges less than 60%, and output has increased nearly 9 times, the output overwhelming majority of increase is by the realization of improving the breed.For example the every per mu yield oil of present kind is only 5～6 kilograms, and the new varieties per mu yield in the planning will reach 25～40 kilograms.Therefore can estimate: along with raising and the output of production efficiency are increased sharply, the price of tea oil will reduce significantly than at present.Even this planning can partly be implemented, add other favorable factors: improve constantly such as the two low rapeseed oil quality in various places, output enlarges rapidly the source that has increased raw material, and the first two contradiction that the present invention faces will be alleviated substantially.Primary stage can be the booming income crowd with promoting target localization.Weigh with nutrition and clinical nutriology standard, such crowd also is simultaneously in the urgent need to changing the object of the sour ratio of edible oil fat.

The present invention's expection: along with constantly popularizing of nutrient knowledge, the personalized edible oil of fatty acid proportion is subject to consumer's favor owing to having unarguable science, and becomes gradually a kind of fashion.After personalized edible oil spreads to a certain degree, there is the resident of consuming capacity can know the average daily edible oil quantity of own family and suitable polyunsaturated fatty acid proportion.Buy oil to the shop except will seeing brand, kind, fatty acid proportion and the content of vitamin E quality requirement that also is absolutely necessary.Even have a meal to the hotel and when ordering dishes, also can propose requirement (each dish cooking oil quantity and fatty acid proportion scope) to edible oil.Further again, carry that edible oil goes to have a meal in the restaurant, collectiveity canteen with good conditionsi under nutritionist's guidance, it also is feasible selecting the ready-mixed oil of suitable fatty acid proportion targetedly.In addition, from development trend, people are also improving gradually to the understanding of the harm that higher fatty acid intake causes human body.Although change relatively difficulty of diet structure fully, the simple edible oil quantity that reduces gradually but is feasible, subject matter is that people are not enough to the harm understanding of too much absorption edible oil.Enforcement of the present invention is to be based upon on the basis of clearly understanding edible oil intake per capita.We have a responsibility for taking full advantage of this advantage, and the A clear guidance consumer starts with from reducing the edible oil intake, changes gradually unsound dietary.Cooperate nutritionist's sincere advice, government organs and various media publicity, add advocating, encouraging to consume oil less, rationally consume oil of edible oil operator, believe and can receive preferably effect.Because the reduction of edible oil picked-up quantity, daily absorb edible oil quantity take the people and also will reduce as the standing specification of standard setting.The quantity that surpass 50 gram people along with daily intake reduce gradually, and the standing main specifications of ready-mixed oil of the present invention also can be reduced to 4 even still less accordingly.Grease production producer releases the accurately standing specification of special-purpose inner wrapping product oil of mark of content of fatty acid, the resident can be according to the per capita edible oil quantity of own family, utilize constant of the present invention and formula to calculate further more accurately personalized polyunsaturated fatty acid ratio, preparation adapts to the ready-mixed oil of the member of this family needs voluntarily.
