Description
Technical field
The present invention relates to a kind of preparation method of sesame paste.
Background technology
It is well known that sesame is made up of kind of skin and seed benevolence, containing abundant grease and protein, eaten with higher
Value, containing about 50% grease, about 25% protein, about 25% carbohydrate and other compositions are practically free of anti-
Trophic factors.
At present, used as one of big oil crops of China three, yield occupies second place of the world to sesame, and its main producing region is mainly mountain
The ground such as east, Henan, Hubei, Hebei.However, sesame very heterogeneity in size, color and luster and maturity when harvesting, impurity content is big
(such as the ratio of mud and fine dirt is big shoulder to shoulder in impurity), along with seed small volume, therefore, extremely it is difficult to clear up.
Sesame is classified according to kind, that is, white sesameseed and Semen sesami nigrum, and sesame paste is, with sesame as raw material, to pass through
The operations such as removal of impurities, cleaning, parch, grinding are processed, and are made the edible pure sesame paste of thick-pasty, and finished product is available for directly edible or enters
One step is processed, and is a kind of senior flavouring and appetizing food, is of high nutritive value, deep to be liked by the masses.
Although though sesame paste early has production in China, only small lot batch manufacture or family workshop type is produced, and fails shape
Into large-scale production.Producer's quality mind is poor, preparation method simple coarse, and troublesome poeration makes product quality be affected.
It is the patent of invention of Tianjin Dongshun Oil Industry Co., Ltd.'s application in the prior art than more typical technique
" a kind of preparation method of sesame paste ", application number " 201510572221.0 ", the date of application is " 2015.9.9 ", and its technique is such as
Under：Screening → washing → stir-fry seed → take the dish out of the pot → lower the temperature → grind → filling, comprises the concrete steps that：
Screening：The impurity preliminary screening such as iron filings that will be mixed into sesame by sesame descaling machine is gone out, in sesame descaling machine
Exit bar magnet is set, can the incomplete iron adsorption of cleaning on the bar magnet；
Washing：Sesame is cleaned by rinsing machine it is clean, it is stirred in the rinsing machine after, the sandstone in sesame will sink to
To the stage of rinsing machine, and sesame can swim in the upper strata of water, at this moment pick up sesame, and sandstone are discharged by the bottom of rinsing machine
Mouth discharge (water-washing process is repeated 3 times)；
Fry seed：Sesame after will be water washed carries out stir-fry seed, the temperature of roasted sesame device interior is maintained at 175 DEG C, continues
Time is 45min, until sesame surface is changed into golden yellow；
Take the dish out of the pot：Sesame appearance seems to reach plumpness very high when taking the dish out of the pot, and at this moment sesame moment takes the dish out of the pot, and is protected when taking the dish out of the pot
The temperature of sesame is held at 175 DEG C；
Cooling：The sesame after taking the dish out of the pot is cooled to normal temperature (using 4 DEG C of pure water to sesame in temperature-fall period between 8min
Numb grain is cooled down)；
Grinding：To lowering the temperature, later sesame is ground, and sesame is put into stone mill and is ground, temperature control during grinding
At 60 DEG C；
It is filling：Finally carry out filling to grinding later sesame paste, be made finished product.
However, above-mentioned sesame paste production technology, has the following disadvantages：
(1), production scale is small, and most of is family workshop type production, its yield mostly in below 20t/d, meanwhile,
It is batch production, such as washes, fries the cooling after seed, taking the dish out of the pot after stir-fry seed, transfer, conveying, the loading and unloading of material is all hand
Work is operated, and troublesome poeration, health and cleanliness factor are poor, product quality various problems is occurred, it is difficult to large-scale production.
(2), production and technical indication is difficult to control to, and carries out subjective judgement with sense organs such as visual, smell with operating personnel entirely,
Not only bother, error easily occur, experience or the qualification requirement to operating personnel are very high, also unhygienic, make production line
Seal is poor.And because technology and Equipment are also not suitable for installing Automated condtrol element additional, control problem is turned into first
Nature defect.

But lower the temperature, and sprayed water in sesame again after stir-fry seed, no matter having sprayed how much moisture, can all influence the quality of sesame paste after grinding,
Because sesame paste is a kind of dispersion of solid-liquid, including liquid grease and denatured protein, the carbon hydrate of solid-state
The conjugate of thing, lignocellulosic and ash content and protein and other materials, solid phase dispersion forms the mixed of stabilization in oil phase
Compound, solid phase contains hydrophilic radical and lipophilic group, but hydrophily is strong more than lipophile, when moisture is sprayed into after frying seed, Gu
Will mutually absorb water and combined with water and release grease, the stability of such sesame paste is just destroyed, and is not the mixing shape of stabilization
State and grease can be separated out, cause oily sauce to separate, influence is edible and outward appearance, and the grease for separating out is susceptible to oxidation, makes sesame
Sauce shortened shelf life.So moisture can not be all added in spite of grinding after frying seed, because now adding water to be conducive to grease
Separate out and be unfavorable for the stabilization of sesame paste and guarantee the quality.
(5), directly it is ground after seed cooling is fried in existing process, do not carry out before the grinding again is clear
Reason, and to fry and form some dust and onal during seed, do not clear up and directly grind, mouthfeel and the nutrition of sesame paste will be reduced
Value.
(6), existing process does not have dust ventilating net, equipment or pipeline nor air-tight state, makes dust overflow, and not only influences
Operating personnel are healthy, also influence workshop hygiene situation, reduce product quality.
(7), existing process does not carry out sterilized and directly filling to sesame paste, easily causes product sanitary index and does not conform to
Lattice.

Wherein, mainly there are two aspects in Arsenic In Food, the source of lead：One is that sesame absorbs in growth course, and two are
Absorbed from the material that container, equipment, packaging etc. are contacted in results, treatment, production process, we will control arsenic, lead to contain
Amount is also to set about from these two aspects, is first that raw material has to comply with standard, next to that must accomplish production line in technological design
Cleaning, device fabrication uses the materials, closed, Automated condtrol such as stainless steel, it is to avoid arsenic, lead are mixed into production process, it is to avoid dirty
Dye.
Meanwhile, moisture can be by roasting control, and roasting can as far as possible reduce moisture, be conducive to sesame
It is the grinding of sauce, preservation, edible.But moisture should not be too low, and moisture is excessively low, the fines content of its sesame can increase, so through vibration
Sesame content is just reduced after sieve separation.
However, arsenic be it is current it is found that one of the most strong material of toxicity, it can not only cause human body Liver and kidney function
Infringement, destruction nerve, hemic and immune system, or even cancer can be triggered；Lead is also a kind of greatly poisonous heavy to harm
Metal, therefore will be to the multiple such as nerve, hematopoiesis, digestion, kidney, angiocarpy and endocrine system after lead and its compound enter body
System is caused harm, and lead poisoning can be caused if too high levels；Escherichia coli can cause the bleeding of serious stomachache and recurrent exerbation
Property diarrhoea, while with heating vomiting etc. performance.Experimental result shows, arsenic, lead in sesame paste obtained in the method in the present invention
Content with Escherichia coli is all significantly lower than national standard, and less than the content of comparative example 1 and 2.
In sum, the application has the advantage that：
