First Claim
Patent Images
1. The process for preparing an oilseed lipid-protein comestible which comprises:
- (a) forming an aqueous suspension of edible oilseed containing suspended oilseed lipid, dissolved oilseed protein, and dissolved oilseed carbohydrate at a pH in excess of the isoelectric range of said protein, said suspension being obtained by aqueous extraction of particulate oilseed material containing lipid, protein, and carbohydrate at a pH in excess of the isoelectric range of said protein;
(b) separating particulate material from said suspension to yield an emulsion containing suspended lipid, dissolved protein, and dissolved carbohydrate; and
(c) separating carbohydrate from said emulsion by filtration employing a semi-permeable membrane which has the capability to retain suspended lipid and dissolved protein as retentate, and to pass dissolved carbohydrate as permeate.

Abstract
An oilseed lipid-protein product adapted for food use is prepared by aqueous extraction of fat containing oilseed materials including the ground raw oilseed or full-fat oilseed flour or flake at a pH in excess of the isoelectric range of the protein for the purpose of solubilizing the protein. Insoluble material is removed by centrifugation or filtration, and soluble carbohydrate is removed from the resulting lipid-protein emulsion by membrane filtration.
