Abstract

Studied hydrolysis on walnut protein with 5 kinds of protease. The result showed that AS. 1398 proteinase was the optimum proteinase. The optimum hydrolytic condition were that concentration of walnut protein was 2.5%, E/S was 7%, temperature was 40℃, pH was 7.5, hydrolytic time was 3 hour. Under this experimental condition, hydrolytic degree of walnut protein was 45.37%, the hydrolyzate has only slight bitter.
