摘要
以底物浓度为10%、Flavourzyme与Papain复合酶比为1:1的条件,利用单因素试验和正交试验,研究了pH值、加酶量、温度、酶解时间对龙虾副产物蛋白质水解度的影响,在此基础上进一步确定了合适的底物浓度。结果表明,Flavourzyme-Papain复合蛋白酶水解龙虾副产物的最佳条件为:pH7.0、加酶量1.5%、温度50～55℃、时间5h,在底物浓度25%的条件下水解,最大水解度为26.2%。
Under the fixed conditions of 10% substrate, Flavourzyme - Papain ratio 1：1, the effects of pH, enzyme amount, temperature, reaction time on hydrolysis degree of Procambarus clarkii byproduct were investigated, and these factors were optimized by orthogonal test. The optimal substrate concentration was also determined. Results showed that the optimal hydrdysis conditions are, pH 7.0, amount of compound enzyme 1.5%, temperature 50-55 ℃, time 5 hours and substrate concentration 25%. The maximum hydrolysis degree reaches 26.2%.
