Abstract

Cottonseed cake was used as the raw material after removal of gossypol from it and the technology for enzymatic hydrolysis of cottonseed protein was studied. The factors affecting the reaction and the application of the product were researched. The results show that if cottonseed cake was hydrolyzed with neutral protease AS1.398, the production yield reached 28.8% and the protein content was 63.28%. Hydorlyzed cottonseed protein can be used as the nitrogen source of fermentation medium.
