摘要
为科学评价生长速度快、抗病能力强的新兴养殖品种"黄优1号"(Pelteobagrus vachelli♀×Pelteobagrus fulvidraco♂)肌肉营养价值,测定其肌肉中常规营养成分、氨基酸和脂肪酸的含量和组成,并与其父本瓦氏黄颡鱼和母本黄颡鱼进行了比较。结果发现:黄颡鱼、瓦氏黄颡鱼和"黄优1号"肌肉中共检测出17种氨基酸,在总氨基酸含量、总必需氨基酸含量以及总鲜味氨基酸含量等方面均以"黄优1号"肌肉中含量最高。"黄优1号"肌肉中富含人体必需脂肪酸,含量高达22.85%,与其母本黄颡鱼肌肉中必需脂肪酸含量接近,略低于其父本瓦氏黄颡鱼肌肉中必需脂肪酸含量。结果表明"黄优1号"具有较为显著的氨基酸和脂肪酸营养价值的双重优势。
＂Huangyou No.1＂（Pelteobagrus vachelli♂×Pelteobagrus fulvidraco♀）is a new freshwater fish breed with advantages of rapid growth and strong resistance to disease.To appraise the nutritional value of＂Huangyou No.1＂,we analyzed the composition and content of amino acids and fatty acids in the muscle of＂Huangyou No.1＂and compared it with that of its parental species.A total of 17 amino acids were detected in the muscle of the three kinds yellow catfish.The contents of the total amino acids,total essential amino acids and total flavor amino acids were highest in the muscle of＂Huangyou No.1＂among the three kinds of yellow catfish.The content of essential fatty acids in the muscle of＂Huangyou No.1＂was 22.85%,which was close to that of yellow catfish and slightly lower than that of darkbarbel catfish.These results showed that＂Huangyou No.1＂has significant nutritional advantages in fatty acids and amino acids.
