摘要: 以高压浸提后的牛骨肉蛋白液(蛋白含量2.15%)为研究对象,通过单因素和响应面法优化试验,分别研究风味蛋白酶和复合蛋白酶的酶解条件对酶解液水解度和氨基态氮含量的影响,进而优选出两种酶单独添加时的最佳酶解工艺条件。结果表明:风味蛋白酶的最佳酶解条件为酶解温度45℃、酶解时间4.3 h、酶添加量50 LAPU/g蛋白质,在此条件下水解度为15.88%;复合蛋白酶的最佳酶解条件为酶解温度45℃、酶解时间4.5 h、酶添加量15 000 U/g,在此条件下水解度达到12.78%。

Abstract: In this study, bovine bone were chosen as raw material (2.15% of crude protein content). Study on the influence of technological condition of enzymolysis by two kinds of protease (flavourzyme and protamex). The research results showed that the optimal hydrolysis conditions of flavourzyme were as follows: temperature 45 ℃, hydrolysis time 4.3 h and the enzyme addition 50 LAPU/g protein. Under this condition, the degree of hydrolysis was 15.88%. The optimum conditions for protamex extraction were found to be hydrolysis at 45 ℃ for 4.5 h with an enzyme/substrate ratio of 1 500 U/g, the degree of hydrolysis under this conditions was 12.78%.

Key words: bovine bone, enzymatic hydrolysis, flavourzyme, protamex, degree of hydrolysis
