摘　　要：牛奶蛋白质的生物利用度引起了人们的广泛关注。奶制品经酶消化后可产生多种生物活性肽,人乳和以牛奶为原料的婴儿配方奶粉都是生物活性肽的潜在来源。分析婴幼儿奶源中生物活性肽的形成及其功能,重点讨论具有营养价值的生物活性肽来源,即人乳和以牛奶为原料的配方奶粉对婴儿健康的影响。此外,评价体外或体内消化对生物活性肽的释放和利用度的影响。人乳和婴儿配方奶粉的代谢作用所产生的生物活性片段及其生物利用度之间存在着很大差异。由于以牛奶为原料的婴儿配方奶粉中的肽组分能够促进健康,所以牛乳蛋白肽对人乳可能是一个有价值的补充。Milk proteins have attracted extensive interest in terms of their bioavailability following ingestion. Enzymatic digestion of dairy products generates numerous peptides with various biological activities. Both human milk and infant formulas based on cow＇s milk are potential sources of bioactive peptides. This review presents knowledge on the formation and function of bioactive peptides from milk feeds intended for infants. Emphasis is placed on the source of the bioactive peptides with the nutritional impact of human milk and cow milk-based formulas on infant health being critically discussed from that perspective.Furthermore,the effect in vitro or in vivo digestion on the release and availability of peptides with bioactive sequences is evaluated. Considerable differences with respect to bioavailability and metabolic effects between the biologically active fragments generated following ingestion of human milk and infant formulas are documented. Peptides from milk protein of bovine origin could be a valuable supplement to human milk as multiple health-promoting properties are attributed to peptide fractions identified in standard cow milk-based infant formulas.
