| 摘 要： | 对工业化生产的食源性低聚肽进行了清除DPPH自由基、抑制亚油酸自氧化2种体系下的体外抗氧化活性的研究。结果表明:在清除DPPH自由基体系中,卵白肽和大豆肽的抗氧化活性最高,其IC50分别为5.767,6.268mg/mL。在抑制亚油酸自氧化体系中,大豆肽和海洋胶原肽对于亚油酸自氧化的抑制率分别达到了75.16%和58.69%。几种食源性低聚肽均有不同程度的抗氧化活性。

| Abstract: | DPPH radicals scavenging activities and linoleic acid autoxidation inhibiting activities of food-derived peptides were studied.The results indicated that the DPPH radicals scavenging activities of albumen peptide and soybean peptide were the highest,with IC50 5.767 mg/mL,6.268 mg/mL respectively;The linoleic acid autoxidation inhibiting activities of soybean peptide and marine collagen peptide were as high as 75.16% and 58.69% respectively.In addition,all peptides samples showed different levels of antioxidant activities. |
