ABSTRACT:
Crushed and de-fatted oilseed is extracted with water at neutral, mildly basic or mildly acidic pH; and is filtered. The filter media allows passage of small fragments of solid cell meat into the filtrate. The filtrate is treated with a base to increase pH to over pH 9, and solids are separated out. Protein is separated from other constituents of the liquid and concentrated, for example by heat-induced or isoelectric precipitation and/or ultrafiltration. The remaining liquid is rich in sugars. The process results in one or more protein products suited for human or animal food ingredients or for production of cosmetics, a sugar rich product suitable for fermentation or use as a feed ingredient, and a fiber-protein animal feed ingredient.
