选取放牧条件下体况良好、体重相近的甘南成年美仁公牦牛 6 头、母牦牛 4 头进行屠宰,采取美仁牦牛肉的肩甲、背最长肌、股二头肌三个部位的分割肉。测定不同部位营养成分、氨基酸和脂肪酸。结果显示:不同部位美仁牦牛肉的蛋白质含量为 22。97%~23。07%,其中股二头肌蛋白质含量最低,背最长肌最高;脂肪含量为1。27%~2。49%,股二头肌脂肪脂肪含量较低,不足 1。27%。氨基酸含量丰富,脂肪酸总量依次为肩甲、背最长肌、股二头肌上脑肉。通过对比分析不同部位美仁牦牛肉中营养成分、氨基酸和脂肪酸等含量存在差异。
Determination and Analysis of Nutritional Components,Amino Acids and Fatty Acids in Different Parts of Meiren Yak Meat
Six adult Meiren male yaks and four female yaks with good physical condition and similar body weight were selected for slaughter under grazing conditions.Take the segmented meat from the shoulder armor,lon-gissimus dorsi and biceps femoris muscle of Meiren yak meat and determine the nutritional components,amino acids and fatty acids of different parts.The results showed that the protein content of Meiren yak meat in different parts ranged from 22.97%to 2 23.07%,with the lowest protein content in the biceps femoris muscle and the highest longissimus dorsi.The fat content was 1.27%to 22.49%,and the fat content in biceps femoris was less than 1.27%.The amino acids content was rich,and the total amount of fatty acids was in the order of shoulder,armor,longissimus dorsi,and upper brain muscle of biceps femoris.The differences of nutritional components,amino acids and fatty acids in different parts of yak meat were analyzed.
