METHOD OF PREPARING FOOD EMULSIFIER FROM HYDRATED DEPOSIT OF VEGETABLE OILS Russian patent published in 1998 - IPC

FIELD: fat-and-oil industry, more particularly confectionery, perfumery and baking industries. SUBSTANCE: claimed method comprises treating vegetable oil deposit with ethyl alcohol at hydration stearolloletsitin to ethyl alcohol ratio ranging from 10:90 to 40-60 weight parts, separating emulsifier from water-alcohol mixture. In order to increase emulsifying properties of the resulting emulsifier, to reduce content of free fatty acids present therein and compounds soluble in acetone and to deodorize food emulsifier, prior to separation of deposit from water-alcohol solution, mixture is heated to 58+-17 C and deposit is then removed from water-alcohol mixture, 0.2+-0.15 weight parts of ethyl alcohol is added thereto, and mixture is boiled to ethyl alcohol content of 0.10+-0.05 weight part in food emulsifier. EFFECT: more efficient preparation method. 1 tbl
