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
