摘　　要：测定并分析了太平洋双色鳗鲡(Anguilla bicolor pacifica)肌肉中营养成分组成与质量分数。结果显示:太平洋双色鳗鲡肌肉中含62.56%、蛋白质15.85%;肌肉中测出氨基酸17种(未测色氨酸),总量为36.33%(干样),其中包括人体必需氨基酸总量(EAA)7种,总量为13.99%(干样),必需氨基酸组成基本符合FAO/WHO评分标准,太平洋双色鳗鲡的限制性氨基酸为(蛋氨酸+胱氨酸)和缬氨酸,其必需氨基酸指数(EAAI)为78.26,5种鲜味氨基酸(DAA)总量为16.58%(干样);脂肪酸中单不饱和脂肪酸占44.41%,多不饱和脂肪酸占16.70%,其中EPA+DHA的占7.33%。该结果表明,太平洋双色鳗鲡具有较高的使用价值与保健作用。Nutritional components of A nguilla bicolor pacifica muscle were analyzed with routine methods. The results showed that contents of moisture, crude protein from fresh muscles were 62.56% and 15.85%. Except Tryptophan, 17 common amino acids were detected from muscles which include 7 essential amino acids （EAA） for human body. In dry sample, the total content of amino acids （TAA） was 36.33%, the content of EAA was 13.99%. The constitutional rate of the essential amino acids accorded with the FAO/WHO standard. The main limited amino acids of A. bicolor pacifica were Methionine＋Cysteine and Valine. The essential amino acids index （EAAI） was 78.26. Five kinds of delicious amino acids （DAA） accounted for 16.58% in dry sample. The content of monounsaturated fatty acid （MUFA） and polyunsaturated fatty acid （PUFA） in fatty acids were 44.41% and 16.70%. The total content of EPA （C20：5n-3） and DHA （C22：6n-3） in fatty acids was 7.33%. The result showed that A. bicolor pacifica had high edible value and health effect, and would be an imoortant cultured soecies in the future.
