| Abstract: | In this research,the substrates were 7S and 11S globulin proteins.Alcalase was selected from the five proteinases,which was the best one to hydrolyze 7S and 11S globulin proteins under the target of antioxidation activity and the degree of hydrolysis and the best condition of Alcalase hydrolyze 7S and 11S globulin proteins was optimized.Then the antioxidative activity of 7S and 11S globulin were determined by the inhibite autooxidation of grease.The results showed that the optimal hydrolytic conditions of 7... |
