Abstract: Rice protein was deamidation by treating with acid and enzyme. Through measuring the deamidated degree and proteolysis, the experiments showed that the method of acid prior to enzyme. Temperature is the most important factor affects the deamidation. Under this experiment, the optimal deamidation conditions were: 0.2N for the concentration of HCl, 5% rice protein, 4h for reaction time and 85℃ for the temperature.

Key words: rice protein, acid deamidation, enzymatic deamidation
