Abstract
A process for separating olein and stearin fractions from an oil containing olein and stearin which process comprises providing a fluid comprising (a) the oil concerned, and (b) a liquid single phase mixture of two components; (i) at least one liquid polyhydroxy compound Or water, with (ii) at least one polar organic liquid, which liquid single phase mixture is substantially insoluble in the oil, and has a density intermediate those of the olein and stearin fractions, and separating the oil into olein and stearin fractions e.g. by either centrifuging the said fluid or allowing the said fluid to stand.
Claims8
A process for recovering olein and stearin fractions from an oil containing olein and stearin fractions, which process comprises providing a fluid comprising:
- (a) the oil, with
- (b) a liquid single-phase mixture having a density intermediate those of the olein and stearin fractions to be separated and consisting, essentially of
- (i) at least 30% by volume of water or at least 20% by volume of at least one aliphatic alcohol containing two or three hydroxyl groups per molecule and having a molecular weight below 1000,
- (ii) not more than 80% by volume of at least one polar organic liquid selected from the group consisting of monohydric alihphatic alcohols, aliphatic aldehydes, and ketones having from 1 to 5 carbon atoms,
- at a temperature below the melting point of the stearin fraction to be separated and at which the liquid mixture is substantially insoluble in the oil, the proportion of oil to liquid mixture being from 10:1 to 1:10 by volume,
- separating the oil into olein and stearin fractions by physical separation into layers and recovering the fractions.
