黄鳝肌肉营养成分的分析

An analysis of the nutritive composition in muscle of Monopterus albus

对黄鳝的稚鳝 (体重 9.2～ 15 .5g)、幼鳝 (体重 6 2 .3～ 76 .0g)、小成鳝 (体重 10 8.3～ 12 1.4g)和大成鳝 (体重 2 2 2 .8～ 2 42 .8g)肌肉中的水分、蛋白质、脂肪含量及脂肪酸、氨基酸的组成进行了分析 ,结果表明 :黄鳝肌肉中的蛋白质含量高达 18.79%～ 19.93 % ,脂肪含量较低。高度不饱和脂肪酸含量占脂肪酸总量的 19.15 % ,必需氨基酸的含量占氨基酸总量的 40 .98% ,谷氨酸的含量很高 ,为氨基酸总量的 16 .95 %。

Contents of moisture, protein and lipid were analyzed in the muscle of mud eel fingerling (weight: 9.2-15.5g), juvenile mud eel (weight:62.3-76.0g), small adult mud eel (weight: 108.3-121.4g) and big adult mud eel (weight: 222.8-242.8g), and so was the composition of fatty acids, amino acids. The contents of protein ranged from 18.79% to 19.93%. The contents of lipid were fairly low. The fatty acids contained 19.15% highunsaturated fatty acids(HUFA). The essential amino acids accounted for 40.98% of total amino acids. The content of glutamic acid was considerably high, reaching about 16.95% of total amino acids.
