Abstract
The present invention is directed to enzyme based methods for removing water insoluble non-starch polysaccharides (NSPs) and/or water soluble or insoluble oligosaccharides from soy products without significantly damaging the proteins contained therein This removal is facilitated by the enzymatic hydrolysis of poly- and oligomeric carbohydrates into monosaccharides and other water soluble sugars. The present invention provides for the production of three streams of useful materials. The first is an enriched protein material comparable to the known SPCs but without significant quantities of undigestible oligosaccharides and polysaccharides. The second is an SPI made from the soluble protein in the hydrolysate which is valuable for high-quality feed, food and industrial uses. The third is the soluble saccharides and hydrolyzed carbohydrates (releasing sugars) that can be converted by fermentation to various valuable bioproducts.
