野生巨(鱼丕)肌肉营养成分测定和分析

Measurement and analysis of nutrition components in the muscle of wild Bagarius yarrelli

对野生巨(鱼丕)(Bagarius yarrelli Sykes)肌肉的营养成分进行测定和分析。结果显示:巨(鱼丕)是一种较少见的具有黄色肌肉的鱼类。巨(鱼丕)含肉率为48.78%、肌肉中水分含量77.28%、粗蛋白含量18.01%、粗脂肪含量2.52%、灰分含量2.19%;肌肉中水解氨基酸总量为14.15%,含量最高为缬氨酸(1.35%),最低为甘氨酸(0.45%);必需氨基酸含量为6.21%,占氨基酸总量的43.89%,氨基酸价为160.81,第一和第二限制氨基酸是亮氨酸和赖氨酸(1973年FAO/WHO标准)。结果表明巨(鱼丕)是一种营养价值较高有待开发的野生鱼类。

Nutrition components in the muscle of wild Bagarius yarrelli were measured and analyzed. The results showed that wild Bagarius yarrelli was a kind of rare fish with yellow muscle. The ratio of flesh in the body was 48. 78%, and the average of moisture content, crude protein, crude fat and the mineral in the muscle were 77. 28% , 18. 01% , 2. 52% and 2. 19% respectively. The amount of hydrolytic amino acids in the muscle was 14. 15% of the total amino acids, the higest was Val（ 1.35% ）, the lowest Gly（0. 45% ）. The total essential amino acids was 6. 21%, 43. 89% of the total amino acids. The amino acid score was 160. 81, the first and the second limiting amino acid were Leu and Lvs as compared with the FAO/WHO suggested level （1973） ： In conclusion, Bagarius yarrelli is of a higher nutritional value to be developed.
