中文摘要:

      目的 分析苏尼特羊肉氨基酸组成以及与其他羊肉氨基酸组成进行对比分析。方法 以锡林郭勒放牧型苏尼特羊肉、乌珠穆沁羊肉、察哈尔羊肉以及两个区域舍饲型小尾寒羊肉为研究对象, 通过氨基酸自动分析仪测定不同样品中氨基酸组成和含量, 并进行比较分析。结果 苏尼特羊肉的水解氨基酸和游离氨基酸含量显著高于乌珠穆沁羊肉和察哈尔羊肉(P<0.05); 苏尼特羊肉的水解氨基酸含量与舍饲型小尾寒羊肉无显著差异(P>0.05), 但是其游离氨基酸含量显著高于舍饲型小尾寒羊肉。5种羊肉必需氨基酸/非必需氨基酸均高于60%, 必需氨基酸/总氨基酸在40%左右, 符合联合国粮农组织/世界卫生组织(United Nations Food Agriculture Organization/World Health Organization, FAO/WHO)人体理想蛋白质模式。结论 苏尼特羊肉水解氨基酸和游离氨基酸组成丰富, 含量较高, 具有较高营养价值和食用品质。

英文摘要:

      Objective To analyze amino acid composition of Sunite mutton and compare with that of other mutton. Methods Taking Xilingol grazing Sunit mutton, Uzhumuqin mutton, Chahar mutton and 2 regional small tail Han sheep as the research objects, amino acid composition and content of different samples were determined by automatic amino acid analyzer, and comparative analysis was conducted. Results The content of hydrolyzed amino acid and free amino acid of Sunit mutton was significantly higher than those of Ujimqin mutton and Chahar mutton (P<0.05). The hydrolyzed amino acid content of Sunit mutton was not significantly different from that of the small tail Han sheep (P>0.05), but the free amino acid content of Sunit mutton was significantly higher than that of the small tail Han sheep. The essential amino acids/non-essential amino acids of 5 kinds of muttons were higher than 60%, and the essential amino acids/total amino acids were about 40%, which conformed to the ideal protein model of the United Nations Food Agriculture Organization/World Health Organization(FAO/WHO). Conclusion Sunit mutton is rich in hydrolyzed amino acids and free amino acids, and has high nutritional value and edible quality.
