摘要: 实验确定山核桃蛋白水解最适宜的酶制剂为风味蛋白酶。蛋白酶最适作用条件为:底物浓度为10%,水解时间为2h,温度为55,pH值为6.5,酶用量为1.5%。不同水解度的蛋白多肽清除羟自由基能力不同,结果表明水解度5%时,自由基清除率最高可达50.90%。

Abstract: The enzyme in this experiment is flavor-enzyme. The best hydrolysis condition was get from the orthogonal experiment. Temperature is 40℃,pH is 6.5, dose of enzyme is 1.5%, hydrolysis time is 2 h, DH is 18.14%. The different DH of walnuts peptides has different ability to scavenge hydroxyl radicals. The results showed that when DH is 5% the scavenging activity is 50.90%.
Key words: walnuts, peptides, hydroxyl radicals, scavenging
