摘要
为了探索出经济实用的酶解猪血的方法,对两种不同来源的蛋白酶其采用单一和复合酶水解鲜猪血的酶解效果进行了比较。结果表明:复合法酶解鲜猪血水解效果最好。复合酶最适水解工艺条件为最初pH7～8、温度50℃、酶底物浓度比(E/S)为6000U/g、底物浓度8%、水解时间8h。
In order to explore the economical practical enzymolysis porcine blood the method, proteases from different sources were studied. The results were as following: combinative enzyme has the best hydrolysis activity to porcine blood. The optimum hydrolysis conditions of combinative enzyme are pH7～8, 50℃, enzyme/substrate ratio 6000U/g, concentration of substrates 8%, hydrolysis time 8h.
