Abstract
The invention relates to a method for recovering soybean phosphatide from soybean oil, and belongs to the fields of food additives and preparation methods thereof. The method for recovering soybean phosphatide from soybean oil comprises the following steps: adding water to crude soybean oil, and slowly stirring and heating to 85-95 DEG C; continuing to stir and hydrate, so as to obtain hydrated phosphatide soybean oil; carrying out continuous twice centrifugal separation to obtain crude soybean phosphatide; and carrying out reduced pressure concentration, so as to obtain concentrated soybean phosphatide. The method for recovering soybean phosphatide from soybean oil disclosed by the invention has the characteristics of being simple in process, strong in maneuverability, suitable for industrial production, high in product quality, high in recovery rate and the like. Through measurement, the extraction recovery rate of the preparation method disclosed by the invention is about 8.9%, and is higher than the standard of 7.5% of the extraction recovery rate of a general process.
Description
Technical field
The present invention relates to a kind of method reclaiming soybean phospholipid from soybean oil, belong to foodstuff additive and preparation method thereof field.
Background technology
Phosphatide is distributed widely in animals and plants circle, is a kind of natural bio-surfactant, is also the moiety of the mankind and animal vegetable tissue cytolemma.Commodity phosphatide is mainly derived from soybean, yolk and corn, and wherein the content of soybean phospholipid and quality all exceed general animals and plants, and content can reach the 1.6%-2.0% of full beans.Soybean phospholipid is actually the mixture of various phosphoglyceride and the derivative thereof existed in soybean.Soybean phospholipid is as natural surface active agent of good performance, there is due to its distinctive chemical structure emulsification, softening, wetting, dispersion, infiltration, solubilising, froth breaking and the effect such as anti-oxidant, be widely used in food, medicine, makeup, weaving, process hides, feed and other industry.
In recent years, the soybean phospholipid Progress of Product Development of China is very fast, but quality product compared with developed countries, also has very large gap, be still in the junior stage at present.China produce per year soybean 1,500 ten thousand tons, wherein 25% that is 3,500,000 tons for the production of soybean oil, if there are half i.e. 1,750,000 tons of soybean to reclaim soybean phospholipid in liquefaction process, then estimate can extract reclaim soybean phospholipid 1.4 ten thousand tons, have very considerable economic benefit.For this reason, a kind of effective recovery soybean phospholipid that extracts from soybean oil of research has obvious economic benefit and social benefit.
Summary of the invention
It is simple, workable that the present invention aims to provide a kind of technique, is applicable to suitability for industrialized production and quality product is high, the rate of recovery the is high method reclaiming soybean phospholipid from soybean oil.
The method reclaiming soybean phospholipid from soybean oil of the present invention, comprises the following steps:
In crude soybean oil, add water slowly stir and be heated to 85-95 DEG C, continue stirring and carry out hydration, obtaining hydrated phospholipids soybean oil, then by obtaining thick fabaceous lecithin after double centrifugation, concentrating under reduced pressure, namely obtaining concentrating soya lecithin.
Preferably, amount of water of the present invention is the 1-3% of soybean oil, and Heating temperature is 90 DEG C, and stirring hydration time is 20min-30min;
Preferred, it is 1000rpm that double centrifugation of the present invention is respectively first time centrifugation rotating speed, and second time centrifugation rotating speed is 3000rpm;
Preferred further, concentration method of the present invention is carry out Vacuum film evaporation at 60 DEG C to concentrate.
The method reclaiming soybean phospholipid from soybean oil of the present invention, has technique simple, workable, is applicable to suitability for industrialized production and quality product is high, rate of recovery high.After measured, be about 8.90% with the extraction recovery of preparation method of the present invention, higher than the standard of 7.5% of general technology extraction recovery.
