Description

A kind of soybean phospholipid processing technology

Technical field

The present invention relates to a kind of soybean phospholipid processing technology, belong to health food processing technique field.

Background technology

Phosphatide is the polar material that a class has particular physiological function, is a kind of tensio-active agent, is the main moiety of people, animal and plant cell membranes in tissue; Natural phosphatide has very high nutritive value and good processing characteristics, phosphatide is not only the important composition composition of people, animal and plant cell membranes in tissue, to absorption, the transhipment of fat, to lipid acid, particularly unsaturated fatty acids plays an important role, soybean phospholipid is the product extracted from the oil foot of production soybean oil, and the content in soybean is 1.2% to 3.2%; The ester that it is made up of glycerine, lipid acid, choline or cholamine, can be dissolved in grease and non-polar solvent; Soybean phospholipid outward appearance is light yellow to light brown powder or translucent viscous liquid material, is slightly with beany, is partially soluble in water, be dissolved in benzene, chloroform, ether, sherwood oil, be insoluble in acetone and acetic ester.

Summary of the invention

The object of the present invention is to provide a kind of soybean phospholipid processing technology, to prepare soybean phospholipid better, supply people edible health.

To achieve these goals, technical scheme of the present invention is as follows:

A kind of soybean phospholipid processing technology, comprises following process:

(1) preheating: after machine squeezing crude oil removes impurity after filtration, pre-heating temperature elevation to 80 degree Celsius;

(2) water hydratable is added: according to the content of phosphatide in oil, and the changing conditions determination amount of water of the phosphatide micelle formed in heat-processed, general amount of water is about 3.5 times of phospholipids content; The water level boiling water added, also have working concentration about about 0.7% hot common salt aqueous solution; Add water speed phosphatide absorption speed and determining, phosphatide water suction then adds water soon and wants fast; Phosphatide water suction is slow, then add water and also want slow; When just having started to add water, stirring velocity wants fast, generally rests between 80 to 100 rpms, and after 20 to 30 minutes, phosphatide has large stretch of cotton-shaped particles generation, slows down by stirring velocity, continuation stirring 20 to 30 minutes, can staticly settle; Upper strata edible vegetable oil after precipitation, after dehydration, is refining oil, and lower floor's oil foot then needs could obtain finished product phosphatide after concentrated;

(3) concentrated: by the phosphatide oil foot after aquation, suck in concentrated cylinder through vacuum, heat up simultaneously and stir; When insulation 80 degrees centigrade, the moisture in vacuum removal phosphatide; In time stirring fluid phosphatide slightly mercerising produces, namely show that moisture meets the requirements, now moisture content is greatly about about 5%, and the phosphatide after concentrated is brown semi solid, namely can be used for food, medicine and industrial;

(4) decolouring of phosphatide: when high-quality phosphatide produced by needs, through concentrated phosphatide, also needs to carry out desolventing technology; The method of desolventing technology: in concentrated cylinder, adds concentrated phosphatide amount 2% to 2.5%, and concentration is the hydrogen peroxide of about 30%, under the condition of 50 degrees Celsius, stops vacuum-sealing decolouring 1 hour; Then start vacuum pump, be warmed up to 70 degrees centigrade, dewater, until the phosphatide color after not having water droplet to decolour in point water vat is light brown.

This beneficial effect of the invention is: the technology of the present invention can the good soybean phospholipid of manufacture mass, meets life requirement and the needs of people, be conducive to the life requirement of people and edible needs, and method is simple and convenient, is applicable to promoting the use of.

Embodiment

Below in conjunction with embodiment, the specific embodiment of the present invention is described, better to understand the present invention.
