Abstract: Protein was extracted from defatted rice bran with protamex and cellulase respectively. The results showed that the extraction rate of rice bran protein by Protamex is obviously higher than that by cellulose; The optimum hydrolysis conditions with protamex are as follows: pH 5.5, Protamex amount 2% , ratio of liquid to material 10:1; Under the conditions extraction rate of rice bran protein is 52.7%.

Key words: rice bran protein, extraction, enzymatic hydrolysis
