摘要
应用中性蛋白酶对豆粕进行水解，酶用量为１６６蛋白酶８０００ｕ／ｇ原料、１３９８蛋白酶９０００ｕ／ｇ原料，料水比为１：１０，保温水解６４－７２ｈ，蛋白质消化率可达７０％以上，氮溶指数可达８５％以上，水解过程中适当添加纤维素酶和α－淀粉酶，对提高蛋白质消化率有利。
Using the neutral protase to hydrolysis the powder of soya bean cake,the protein digestive rate can reach above 70% and the dissolving nitrogen index can be above 85% as the 166 protase activily 8000 u/g material or the 1398 protase 9000 u/g material ,the proportion between material and aqua 1:10,Keeping the optimum temperature of the enzyme and the hydrolytic time 64￣72h. It's useful for improving protain digestive rate to add cellulase and α amylase properly during the hydrolysis prcess.
