摘要
对猪骨粉进行酶解,探讨酶的种类、温度、时间、底物质量分数和pH值对酶解效果的影响。在单因素试验的基础上,对酶解温度、时间、底物质量分数和pH值4因素进行正交试验。结果表明:选用木瓜蛋白酶、酶用量10000U/g、在55℃、底物质量分数5%、pH8的条件下酶解4h,酶解效果最好。
The enzymatic hydrolysis of pig bone powder was optimized with respect to enzyme type,temperature,time,substrate concentration and pH by one-factor-at-a-time method in combination with orthogonal array method.The best hydrolysis results were achieved by using papain to hydrolyze pig bone powder for 4 h at pH 8,55 ℃ and an enzyme dosage of 10000 U/g.
