中文摘要:
       对珠江长臀鎨[Cranoglanisbouderius(Richardson)]的含肉率和肌肉营养成分进行了测定。结果表明,长臀鎨含肉率平均为69.42%,粗蛋白15.47%,粗脂肪7.43%,水分75.38%,粗灰分1.15%;检测出的17种氨基酸,总量为64.20%(干样),其中人体必需氨基酸总量29.28%,占氨基酸总量的45.62%,必需氨基酸的构成比例基本符合FAO/WHO的标准,必需氨基酸指数为 58.70;鲜味氨基酸含量为24.83%,占氨基酸总量的38.64%。长臀鎨是一种营养丰富、适合养殖推广的优质淡水鱼类。
英文摘要:
      Nutritional components in the muscle of Cranoglanis bouderius were analyzed using ordinary standard methods. The results showed flesh rate was 69. 42%,and contents of moisture,crude protein,crude fat,ash were 75.38%,15.47% , 7.43% and 1.15 % in fresh muscle,respectively. The total mount of 17 kinds of amino acids was 64. 20%(dry matter,with essential amino acids of 29.28%,accounting for 45.62% in total amino acids. According to nutrition evaluation in amino acids score(AAS) and chemical score(CS),the essential amino acid index(EAAI) was 58.70. The constitutional rate of the essential amino acids accorded with the FAO/WHO standard basically. The content of tasty amino acids was 24. 83 %,comprising 38.64% in total amino acids.
