摘　　要：与人工合成的食品抗氧化剂相比,天然抗氧化肽更加安全可靠,因而从农副产品中制备天然抗氧化肽替代合成抗氧化剂已越来越引起人们的兴趣。此外有报道证实抗氧化肽还具有抗癌、抗诱导及抗衰老等其他生物活性。因此抗氧化肽不仅在食品工业,而且在医药、化妆品和整形外科等领域中都得到广泛应用。近十几年来,抗氧化肽由于其重要功能已越来越受到人们的关注,已成为国内外研究热点。本文大体介绍了抗氧化肽的天然来源,重点讲述了抗氧化肽的粗提和分离纯化,并对抗氧化能力的评价方法、影响因素进行了总结,最后介绍了抗氧化肽的应用现状。Natural antioxidant peptides are safer than synthetic food antioxidants, hence the growing interest in the substitution of synthetic food antioxidants by natural antioxidant peptides has focused research on their preparation from inexpensive or residual sources from agricultural industries. Except for antioxidant ability, other biological properties such as anticarcinogenicity, antimutagenicity and antiaging activity have been reported for natural antioxidant peptides. Hence antioxidant peptides are not exclusive concern for the food industry, which are widely needed to prevent deterioration of other oxidisable goods, such as cosmetics, pharmaceuticals and plastics. In the last few decades, antioxidant peptides have been given more and more attentions for its important function and become the focus of domestic and foreign studies. In this review, after presenting general aspects about natural source of antioxidant peptides, is to focus on the crude extraction and purification of antioxidant peptides from agricultural and industrial wastes, as well as to summarize the evaluating indicators and influencing factors of antioxidant activity. At last the application of antioxidant peptides is presented.
