摘　　要：[目的]提高牦牛乳的开发利用价值以及牦牛乳产品的附加值。[方法]对青海高原牦牛乳氨基酸、脂肪酸组分及其含量进行了测定。[结果]在牦牛乳中共检测到16种氨基酸,其谷氨酸、异亮氨酸、酪氨酸和精氨酸含量相对较高,赖氨酸、甘氨酸、蛋氨酸和丙氨酸含量相对较低。牦牛初乳中总氨基酸含量(5.485%)显著高于常乳。在牦牛初乳和常乳中均检测到28种脂肪酸,其中饱和脂肪酸19种,不饱和脂肪酸9种。常乳中的油酸和硬脂酸含量显著高于初乳。[结论]该研究可为牦牛乳的开发利用提供基础数据与科学依据。[ Objective ] The research aimed to improve the development and utilization values of yak milk and the added value of yak milk products. [ Method] The components and their contents of amino acids and fatty acids in the milk of yak in Qinghai - Tibet Plateau were deter- mined. [ Result] 16 kinds of amino acids were detected in yak milk. The content of glutamic acid, Ile, Tyr and Arg were relatively higher, and that of lysine, glycin, methionine and aminopropionic acid were relatively lower. The content of total amino acids in colostrum of yak was 5. 485%, which was significantly higher than that of normal milk. 28 kinds of fatty acids were detected in colostrum and normal milk of yak, including 19 kinds of saturated fatty acids and 9 kinds of unsaturated fatty acids. The contents of oleic acid and stearic acid in normal milk were significantly higher than that of colostrum. [ Conclusion ] The research could provide basic data for the development and utilization of yak milk.
