| Abstract: | Peanut protein concentrate(PPC) pretreated by physical method was limitedly hydrolyzed by papain protease to improve its solubility.On the base of single factor experiments,the optimum conditions of limited enzymatic hydrolysis were concluded by response surface methodology(RSM).The results showed that the optimum conditions were as follows:enzyme dosage 0.291 3%,reaction time 18.95 min,temperature 46.70℃.Under the optimum conditions,the nitrogen soluble index of the modified PPC was 86.32%. |
