摘　　要：采用常规营养分析方法测定凹尾拟鲿肌肉中氨基酸和脂肪酸的百分含量,并评价其营养价值。结果表明,凹尾拟鲿的肌肉中含有16种氨基酸,氨基酸总量为73.67%,其中7种必需氨基酸总含量为30.40%,6种鲜味氨基酸含量为3.39%;必需氨基酸指数为73.48。凹尾拟鲿的第一限制性氨基酸是甲硫氨酸。此外,肌肉中含有25种脂肪酸,包括11种多不饱和脂肪酸,其总含量为23.77%。C22:6为4.41%,高于黄颡鱼。凹尾拟鲿肌肉中氨基酸种类齐全、必需氨基酸与鲜味氨基酸含量较高,是营养价值与经济价值都较高的优质鱼类。The conventional nutritional analysis method was used to determine the content of amino acids and fatty acids in the muscles of Pseudobagrus emarginatus,and to evaluate its nutritional value.The result showed that there were 16 kinds of amino acids in the muscles of Pseudobagrus emarginatus,and the total amount of amino acids was 73.67%,of which the total content of 7 essential amino acids was 30.40%,the content of 6 kinds of delicious amino acids was 3.39%,and the essential amino acid index(EAAI)was 73.48.The first limited amino acid of the species was methionine.In addition,muscle contained 25 fatty acids,including 11 polyunsaturated fatty acids,with a total content of 23.77%.C22:6 was 4.41%,which was higher than that of yellow catfish.There were a wide range of amino acids,essential amino acids and umami-flavored amino acids in the muscle of Pseudobagrus emarginatus.It was a high-quality fish with high nutritional value and economic value.
