Gluten is heat treated at a relatively high temperature for a short period and then is extracted with an organic solvent to improve filterability and purity. Mixtures of the purified gluten and other protein materials have high nutritional value.

Gluten treatment

Vegetable protein source materials are dispersed in water at a pH in the range of 2 to 6 and an acid phytase is included therein. The acidic extract containing soluble protein is separated and dried to yield a solid protein of desirable character. A protease can also be used to improve the characteristics of the protein.
