摘　　要：对鮸鱼肌肉和副产物营养成分进行测定,鮸鱼肌肉和副产物水分含量分别为79.65%与69.15%,蛋白质含量分别为18.65%与19.36%,粗脂肪含量分别为0.24%与3.90%,灰分含量分别为1.15%与3.75%。鮸鱼肌肉和副产物的氨基酸总量(TAA)分别为18.58%与15.47%,必需氨基酸(EAA)质量分数分别为7.65%与5.52%,但只有鮸鱼肌肉的EAA/TAA(41.17%)与EAA/非必需氨基酸(69.99%)符合FAO/WHO优质蛋白质标准。氨基酸评分和化学评分的结果表明鮸鱼肌肉和副产物的第一限制性氨基酸均为蛋氨酸。鮸鱼肌肉必需氨基酸指数(EAAI)为89.07,副产物的EAAI为61.78。鮸鱼肌肉和副产物都含有丰富的丁酸、棕榈油酸、油酸、神经酸、二十二碳六烯酸、Mg、Ca、K和Fe。鮸鱼肌肉和副产物是高蛋白质、低脂肪、富含矿物质的食品源。To determine the nutrients contents in Miichthys miiuy muscle and by-products.The contents of moisture in Miichthys miiuy muscle and by-products were 79.65%,69.15%;crude protein were 18.65%,19.36%;crude fat were 0.24%,3.90%;and crude ash were 1.15%,3.75%,respectively.Total amino acids(TAA)contents of Miichthys miiuy muscle and by-products were 18.58%,15.47%,and essential amino acids(EAA)contents were 7.65%,5.52%,respectively.However,only EAA/TAA(41.17%)and EAA/non essential amino acids(NEAA,69.99%)of Miichthys miiuy muscle met FAO/WHO standard for protein profile.According to amino acid score(AAS)and chemical score(CS),methionine was the first limited amino acid in Miichthys miiuy muscle and by-products.The essential amino acids index(EAAI)of Miichthys miiuy muscle and by-products was 89.07,61.78,respectively.The contents of butyric acid,palmitoleic acid,oleic acid,nervonic acid,docosahexaenoic acid(DHA),magnesium(Mg),calcium(Ca),potassium(K)and iron(Fe)were high in Miichthys miiuy muscle and by-products.Miichthys miiuy muscle and by-products are kinds of nutrition rich food source with high content of protein,low content of fat and high contents of mineral.
