Abstract: The factors affecting hydrolysis of corn gluten meal by alkaline protease were studied by mono-factor analysis,and the optimum technique parameters were determined by orthogonal test.The results showed that under the optimal conditions of:concentration of substrate 3%,enzyme to substrate ratio 3.0%,temperature 45 ℃,hydrolysis time 1 h and pH 9.0,the hydrolysis of degree is 38.12%.

Key words: corn gluten meal, alkaline protease, hydrolysis, degree of hydrolysis
