【摘要】 应用正交实验优选鱼鳞蛋白酶解的最佳条件。结果表明，鱼鳞酶解宜采用条件温和的枯草杆菌中性蛋白酶，用醋酸作软化的预处理，可使鱼鳞蛋白得到较高程度的水解，酶解时最佳温度为50℃，酶量宜采用1．5％，酶解的最佳时间为6h，底物浓度宜选择20％。更多还原

【Abstract】 Orthogonal design was chosen to hydrolyse scale with enzyme. The result showed that neutrase can be used to hydrolyse scale, and can reach high degree of hydrolyse by softening pre-treatment with acetate acid. The optimum conditions of neutrase was temperature 50℃,con-centration of 1. 5%, time of 6h, substrate consistency of 20%.更多还原
