摘要
以49日龄的仙湖鸭为对象,对其肌肉的常规生化成分及氨基酸进行分析,结果表明:仙湖鸭的必需氨基酸含量为(34.32±0.81)%,其中精氨酸含量最高,苏氨酸含量最低;非必需氨基酸含量为(25.96±0.65)%,其中谷氨酸含量最高,胱氨酸含量最低;总氨基酸含量为(60.28±1.18)%;鲜味氨基酸总含量为(20.14±1.49)%,其中谷氨酸含量最高;氨基酸评分和化学评分表明,限制性氨基酸分别为苏氨酸、缬氨酸和组氨酸,必需氨基酸指数为41.46。
The meat chemical contents and amino acids of Xianhu No.3 ducks at 49 day were analyzed in this study.The content of the essential amino acids（EAA） indices was（34.32±0.81）%,among which the value of arginine was the highest,while the content of threonine was the lowest.The amount of the non-essential amino acids（NEAA） indices was（25.96±0.65）%among which the value of glutamic acids was the highest,while the content of cysteines was the lowest.The value of total amino acids indices was 60.28±1.18.The amounts of flavour amino acids were（20.14±1.49）%among which the content of glutamic acids was the highest.By analysis of the amino acids scores and chemical scores,the limited amino acids were threonine,valine and histidine,respectively.The value of the essential amino acids indices（EAAI） was 41.46.
