Abstract
The present invention relates to an edible oil containing diglyceride. Said edible oil contains 58-97.9% of triglyceride, 2-39.9% of diglyceride, monoglyceride whose content (weight percentage) is less than 5% and contains no 0 and free fatty acid whose content (weight percentage) is less than 3% and contains no 0. The content of diglyceride in said invention is reasonable, it not only can obtain the effect of promoting combustion of body fat, but also has the action of reducing body weight, said edible oil can be identical to salad oil and other cooking oil in the working propert, and can be used in fat processing field for substituting fat or partially substituting fat.
Description
Technical field
The present invention relates to a kind of edible oil that contains sweet diester.
Background technology
Edible oil is as the essential material of people's daily life, people's physiological metabolism risen make important effect, and along with Chinese people's growth in the living standard, the consumption figure of edible oil also increases very fast, and the inner wrapping edible oil has moved towards huge numbers of families.When Chinese people's living standard improved, the incidence of disease of rich man's diseases such as obesity also constantly rose, and part crowd by satisfying beyond the common demand, also begins to wish to access more healthy to the requirement of edible oil, and the edible oil of strong health care is arranged.
Sweet diester (Diglyceride, english abbreviation DAG) is the DG that fatty acid composition comprises C8-C22 saturated fatty acid or unrighted acid.Studies confirm that much that in recent years sweet diester has the obesity of preventing, prevents the effect that body weight increases, and sweet diester has and the similar character of sweet three esters, therefore can be used for edible oil.
Summary of the invention
The object of the present invention is to provide a kind of body fat that can promote to burn, thus the edible oil that contains sweet diester of the strong health care of tool.
The object of the present invention is achieved like this: edible oil of the present invention comprise sweet three esters, the 2-39.9% of 58-97.9% sweet diester,＜5% and do not comprise a sweet ester of 0,＜3% and do not comprise 0 free fatty, above content is weight percentage.
The weight of unrighted acid accounted for the sweet diester of 50%-100% during preferred its aliphatic acid of described sweet diester was formed, and the weight of unrighted acid accounted for the sweet diester of 70%-100% during more preferably aliphatic acid was formed.The weight percentage of sweet diester is preferably 20-35%, can have the effect of good reduction body fat, does not influence its result of use as cooking oil again.
Edible oil of the present invention also can include antioxidant, and antioxidant adds in strict accordance with the regulation of relevant national standards GB2760 " food additives use sanitary standard ".Antioxidant can be selected for use one of following or their mixture: butylated hydroxy anisole (BHA), dibutyl hydroxy toluene (BHT), ditert-butylhydro quinone (TBHQ), n-propyl gallate (PG), Tea Polyphenols, sodium phytate, Radix Glycyrrhizae antioxygen thing, ascorbyl palmitate, Rosmarinus officinalis extract.
Sweet diester among the present invention can obtain with following method: grease and glycerine carry out ester exchange reaction or aliphatic acid and glycerine and carry out ester exchange reaction, and ester is handed over available chemical method of reaction and enzyme process, the industrial enzyme process of preferentially selecting for use.The present invention is also without particular limitation to the grease that uses, as long as it is a kind of common edible oil, comprise natural animal oil, vegetable oil, fat and by its refining fat that obtains by methods such as ester exchange reaction, hydrogenation, fractionation, the preferred soya-bean oil of grease, rape oil, corn oil, palm oil, linseed oil, safflower wet goods vegetable oil and refining fat therefrom.
The refining concocting method of edible oil of the present invention is as follows:
Contain lipase, aliphatic acid, glycerine, monoglyceride etc. in the aforesaid product that contains sweet diester, need remove accessory substance by separation and purification.Conventional separation method has rectifying, molecular clock etc.Usually molecular clock is more effective.Glycerine is removed in washing, and molecular clock is removed most of monoglyceride and aliphatic acid then, stays sweet three esters of diglyceride and part.By measuring the content of sweet diester in the mixture, sweet diester allotment to the level that requires, is added the edible oil and fat product that other component such as additive can obtain containing sweet diester simultaneously according to filling a prescription.
Technique effect of the present invention is: because sweet diester only contains two aliphatic acid, its boiling point can be lower than 20 degrees centigrade of corresponding edible oils, and temperature is higher during the cooking of domestic traditional consumption habit, when therefore 100% sweet diester uses as cooking oil, more easily produce oil smoke, influence operating characteristics, so must use with the allotment of part grease; Simultaneously because sweet diester contains a hydroxyl, and frost resistance dies down, and preservation is easily separated out under the low temperature, can not influence the outward appearance of product, so the content of sweet diester be difficult for also too high by salad oil national standard (0 degree centigrade 5.5 hours still keep as clear as crystal).The content of sweet diester is reasonable among the present invention, can reach to promote the body fat effect of combustion, thereby have the obesity of preventing, prevent the effect that body weight increases, and does not influence the outward appearance and the cooking performance of edible oil again.Edible oil of the present invention can same salad oil, and ready-mixed oil equally uses, and can be used for that fat processing replaces or part replaces fat.
The invention will be further described below in conjunction with embodiment.
