摘  要：
牛奶和羊奶都可以作为婴儿配方奶粉的乳基来源,但二者的营养素构成和维生素和矿物质含量存在明显的差异。羊奶比牛奶含有较少的αs1酪蛋白和较多的β酪蛋白,非蛋白氮含量也高于牛奶。羊奶中的脂肪球要显著小于牛奶,小直径的脂肪球分布明显高于牛奶,脂肪球总表面积明显大于牛奶,山羊奶中还含有很高比例的短链和中链脂肪酸、共轭亚油酸和长链多不饱和脂肪酸,而且ω-3长链多不饱和脂肪酸含量高于牛奶。羊奶中的低聚寡糖含量比牛奶中的更多,且种类和结构也更接近于人乳寡糖。羊奶作为乳基的婴儿配方奶粉较之牛乳基配方奶粉具有特有的营养特性和潜在的健康益处。

摘  要：
The nutrient composition and vitamin and mineral content of cows' milk and goats' milk are significantly different,even though both of them could be used as a source of milk-based infant formula. In protein,goat milk contained less αs1-casein and more β-casein than milk,and the non-protein nitrogen( NPN) level was higher than milk. Compared to lipids in cows' milk,fat globules in goat's milk were significantly smaller. What's more,fat globules in small diameters distribute was more widely in goat's milk and the total surface area of fat globules in goat's milk was significantly higher. There was high proportion of short and medium chain fatty acid,as well as conjugated linoleic acid( CLA) and long-chain polyunsaturated fatty acids( LCPUFA) in goat's milk. In addition,ω-3 LCPUFA in goat's milk were higher than that in cow's milk. Furthermore,the content of oligosaccharides in goat's milk was more than that in milk,and the species and structure in goat's milk were closer to oligosaccharides in human breast milk. Therefore,goat milk as a source of milk-based infant formula could have great market potential because of the unique nutritional characteristics and potential health benefits.
