酪蛋白水解物的酶法修饰优化与抗氧化活性改善（Enzymatic Modification of Casein Hydrolysates by Plastein Reaction and Improvement in Antioxidant Activity）
酪蛋白水解物 抗氧化活性 类蛋白反应
2010/1/28
利用木瓜蛋白酶对酪蛋白水解,并对所得到的水解物进行类蛋白反应修饰，制备高活性抗氧化肽。以水解物的游离氨基含量变化为响应值，利用响应面分析法对类蛋白反应条件进行优化，得到适宜条件为：酶添加量为500U/g，温度30℃，底物质量分数50%，反应时间5.6h。毛细管电泳分析确认，水解物经类蛋白反应修饰后肽分子组成发生变化。抗氧化活性分析结果表明，所制备的3个修饰产物对3种自由基的清除能力显著提高。
