| 摘 要： | 分析与评价了鲣（Katsuwonus pelamis）、东方狐鲣（Sarda orientalis）和扁舵鲣（Auxis thazard）3种鲣鱼背部肌肉的营养成分。结果显示：1）3种鲣鱼的粗蛋白质量分数为22.86%～24.65%,粗脂肪质量分数为1.41%～2.51%,3种鲣鱼均含有丰富的常量和微量元素;2）鲣和东方狐鲣背部肌肉均检出17种脂肪酸,而扁舵鲣检出23种,其∑PUFA/∑SFA分别为1.17、0.93和1.14,n-6/n-3系∑PUFA值分别为0.07、0.04和0.11,此外,鲣背部肌肉的多不饱和脂肪酸相对质量分数为38.98%,高于东方狐鲣的33.64%和扁舵鲣的37.93%;3）东方狐鲣背部肌肉的必需氨基酸质量分数和必需氨基酸指数（EAAI）分别为35.10%和0.90,略高于鲣的33.95%和0.89与扁舵鲣的32.51%和0.89。 |

| Abstract: | We evaluated the nutritional components in back muscles of three kinds of skipjacks （Katsuwonus pelamis, Sarda orientalis and Auxis thazard）. The results showed that： 1 ） the crude protein contents of three kinds of skipjacks were 22. 86%～24. 65%, while crude fat contents were only 1.41% ～ 2.51%. Minerals were abundant in their back muscles. 2） Seventeen kinds of fatty acids were detected in K. pelamis and S. orientalis, while 23 kinds in A. thazard. The ratios of ∑ PUFA/∑ SFA were 1.17, 0. 93 and 1.14, while the ratios of n6/n-3 ∑PUFA were 0. 07, 0. 04 and 0. 11, respectively. The content of poly-unsaturated fatty acids in back muscle of K. pelarnis was 38.98% , higher than 33.64% of S. orientalis and 37.89% of A. thazard. 3 ） Essential amino acids content and essential amino acids index （EAAI） of S. orientalis were 35.10% and 0. 90, respectively, higher than 33.95% and 0. 89 of K. pelamis, and 32. 51% and 0. 89 of A. thazard. |
