Abstract
Finely divided proteinaceous solids suspended in a non-polar organic liquid are formed into agglomerates by contacting the suspension with an immiscible polar liquid comprising selected alkanol-water mixtures, agitating the 3-phase system to effect agglomeration, separating the agglomerates and recovering the proteinaceous solids. The proteinaceous solids are usually derived from cereal grains or legume seeds, particularly those on which a milling, fractionation or solvent extraction is carried out in a non-polar organic liquid medium.
Claims18
A process for agglomerating and separating finely divided proteinaceous solids from a non-polar organic liquid suspension thereof, comprising:
- (i) contacting the suspension with a solids-agglomerating amount of an immiscible polar liquid comprising lower alkanol-water mixtures, the amount of water being chosen within the range of about 7 to about 24 wt% based on the alkanol;
- (ii) agitating the 3-phase system to effect the desired agglomeration of the solids;
- (iii) separating the agglomerates from the organic liquid suspending medium;
- and
- (iv) recovering the proteinaceous solids.
