Abstract
An enzymatic-based process of extracting value added products from oil seed and grain biomasses is described. The process comprises an alkaline pretreatment step followed by treatment with a proteolytic enzyme, and provides increased product yield and solubility. The products obtained can be soluble protein/peptide and purified dietary fiber. The use of such a process in the production of a food, drink, cosmetics, feed or feed additive product is also described.
Claims43
A process for producing a protein- and/or peptide-enriched fraction and a dietary fiber-enriched fraction from a biomass comprising;
- a) a pretreatment step of incubating the biomass in an aqueous solution under mild alkaline conditions and at a temperature of about 85° C. or more to obtain an aqueous slurry;
- b) an enzyme hydrolysis step of treating the aqueous slurry with a proteolytic enzyme under conditions suitable for the proteolytic enzyme activity;
- and
- c) obtaining a liquid fraction and a solid fraction from the proteolytic enzyme-treated slurry of b),
- wherein the liquid fraction is enriched in proteins and/or peptides and the solid fraction is enriched in dietary fibers and wherein the mild alkaline conditions comprise a pH above 7 and not higher than about 11.
