A2β-酪蛋白的功能性及其在乳制品中应用的研究进展

The Function of A2β-casein and Its Application Progress in Dairy Products

  • 摘要: 牛奶中富含多种营养成分,包括蛋白质、脂质、碳水化合物等,每100 g牛奶中就含有3 g蛋白质,其中主要包括乳清蛋白和酪蛋白。β-酪蛋白占牛奶蛋白总量的24%~28%,其主要包括两种基因型:A1型与A2型。A1β酪蛋白经消化后产生的β-酪啡肽-7会导致人体消化功能紊乱、心血管疾病等不良反应。A2β-酪蛋白则产生较少甚至并不产生β-酪啡肽-7,在胃肠道消化、提高抗氧化功能、降低胆固醇浓度等方面具有益生作用。本文综述了β-酪蛋白基因型在人体内消化后所产生的影响,并阐述了A2β-酪蛋白的益生功能,讨论其对人体健康的作用。并从β-酪蛋白基因型在乳制品中的应用入手,阐述A2β-酪蛋白乳制品的研究进展,为今后乳制品中A2β-酪蛋白的功能研究提供指导意义。

     

    Abstract: Milk is rich in many nutrients, including protein, lipids, carbohydrates, etc. Every 100 g of milk contains 3 g of protein, including mainly whey protein and casein. β-casein accounts for 24%~28% of total milk protein, and it mainly consists of two genotypes: A1 and A2. A1β-casein produces β-casein-7 after digestion, which can cause digestive disorders, cardiovascular diseases, and other adverse effects in humans. A2β-casein produces less or no β-casein-7 and has beneficial effects in gastrointestinal digestion, improving antioxidant function and lowering cholesterol concentration. This paper reviews the effects of β-casein genotypes after digestion in humans and discusses the probiotic functions of A2β-casein and its effects on human health. Moreover, the research progress of A2β-casein dairy products is described from the application of β-casein genotypes in dairy products to provide guidance for future research on the function of A2β-casein in dairy products.
