中文摘要: 采用木瓜蛋白酶水解大豆球蛋白制备抗氧化肽。以自由基的清除率为评价指标,通过单因素试验和正交试 验确定酶解最佳条件。结果显示:最佳条件为 pH7.5,酶和底物比 8 000 U/g,水解时间 3 h,温度 60 ℃。优组合条件下的 羟自由基清除率为 77.6 %,超氧阴离子的清除率为 47.3 %。
Abstract:Glycinin was hydrolyzed by papain to produce antioxidant peptide. Base on the scavenging rate of radical, optimum enzymatic hydrolysis conditions were determined by single-factor and orthogonal test. Results showed that these optimum conditions were followed: pH 7.5, 8 000 U/g of enzyme concentration, 3 h of reaction time and 60 ℃. In these conditions, the scavenging rate of hydroxyl radical and superoxide anion were 77.6 % and 47.3 % respectively.
