摘  要:
以鱼鳞蛋白为原料,采用Neutrase蛋白酶酶解鱼鳞蛋白制备抗氧化活性肽,结合单因素实验筛选关键因子,通过响应面分析法,以.OH自由基的清除率为响应值,确定制备鱼鳞抗氧化活性肽的最佳工艺条件为:酶解时间5h、酶解温度50℃、底物浓度5.51%、pH5.64、酶用量4.12%,该条件下得到的鱼鳞抗氧化活性肽对.OH的清除率达78.82%。

摘  要:
In this paper,antioxidant activity peptide was prepared by Neutrase prolease enzymplysising from fish scale protein.Combining with single factor experiment,key factors were screened.Response surface analytical method was used,taking the clearance of ·OH free radical as the response value,and finally the optimum conditions of preparing fish scales antioxidant activity peptide were:time 5h,temperature 50℃,substrate concentration 5.51%,pH5.64,and enzyme concentration 4.12%.The clearance of fish scales antioxidant activity peptide to ·OH free radical was 78.82% under this condition.
