摘　　要：为分析甘肃祁连清泉羊羔肉中脂肪酸、氨基酸组成与含量,分别运用气相色谱一质谱联用法(GC-MS)和氨基酸自动分析测定法对羊羔肉进行定量测定,并与甘肃平川和玉门羊羔肉进行比较。结果表明:清泉羊羔肉与平川、玉门羊羔肉中的脂肪酸均以饱和脂肪酸为主,但清泉羊羔肉中单不饱和脂肪酸含量较高,其中油酸与亚麻酸含量更丰富。清泉羊肉氨基酸与平川羊肉相比,除了谷氨酸之外,其他的所有氨基酸的含量均明显高于平川羊肉,与玉门羊肉相比,清泉羊肉中必需氨基酸、非必需氨基酸含量均略低于玉门羊肉。因此,从脂肪酸和氨基酸含量及比例构成方面评价,清泉羊羔肉具有较高营养价值与保健功能。In this study, gas chromatography-mass spectrometry（GC-MS）, automatic amino acid analyzer were applied to analyze the composition and content of fatty acid, amino acid in Gansu Qilian Qingquan lamb meat. And compared with Pingchuan, Yumen lamb meat. The results demonstrated that the fatty acid in Qingquan Lamb and Pingchuan and Yumen Lamb were mainly saturated fatty acid, but Qingquan Lamb had higher content of monounsaturated fatty acid, and oleic acid and linolenic acid were more abundant.Compared with Pingchuan lamb,Qingquan lamb amino acid content was significantly higher than that of Pingchuan lamb except glutamic acid.Compared with Yumen lamb, the essential amino acid and non-essential amino acid content of Qingquan lamb were slightly lower than those of Yumen lamb. Therefore, the content and composition of fatty acid and amino acid were evaluated, Qingquan lamb meat has higher nutritional value and health function.
