Fig. 5. Ability of polyphenols extracts to inhibit BSA oxidative fragmentation induced by 500 mM AAPH. (a) Remaining protein: Lane 1, PC (positive control), BSA; lane 2, NC(negative control), BSA þ 500 mM AAPH; lane 3e13, BSA þ 500 mM AAPH þ treated oat extract (C: heating-only treatment, E: enzyme treatment, 0e75: treating time in min). (b) Protection rate (CK: heating-only treatment, TREAT: enzyme treatment). Error bars represent the standard deviations of three individual replicates.
