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.

Enzyme-based protein separation and enrichment from soy meal, wheat meal, and other protein-rich materials derived from plant seeds, fruits and other biomass

Improved enzyme based methods of separating protein from protein-rich material are provided. A method can include utilizing a modeling equation to more effectively hydrolyze the various types of carbohydrates present in a protein-rich material. A method can include a fed-batch method of incrementally adding a protein-rich material, an enzyme broth, or both a protein-rich material and an enzyme broth. A method can also include partially or completely recycling the hydrolysate.

Enzyme based methods of separating protein from protein-rich material

A method for producing arabitol may include providing a fermentation culture having a microorganism and a carbon source; allowing the microorganism to ferment the carbon source; monitoring a process condition of said step of allowing the microorganism to ferment the carbon source; and collecting a product from the fermentation culture after said step of monitoring a process condition indicates that a predetermined change in the process condition has occurred. Other methods may include steps of providing soybean-based lignocellulosic hydrolysate as a carbon source for a fermentation culture, and modifying the pH of one or more of the growth phase and the stationary phase of a fermentation process.

Production of arabitol

The present invention is directed to enzyme based methods for separating protein from protein-rich materials derived from plant seeds, fruit, or other biomass and products made therefrom. The protein content in the resulting products is improved by separating and removing the carbohydrates from around the proteins in, for example, soybean meal. 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.
