Abstract: Glutaminase modification process of rice glutelin was studied. The influences of the ratio of glutaminase to protein, reaction temperature and pH to deamidated process were studied, using deamidation degree (DD) and solubility as indexes. The process conditions were optimized by Orthogonal on the base of the results of single factor test. The results showed that the optimal conditions were as follows: the ratio of glutaminase to protein of 1:7, 37℃, pH7.0. At the optimal conditions, the DD reached to 52.76%, and solubility of modified rice glutelin was 93.78%.
