唇鲮肌肉中营养成分分析与品质评价

采用常规测定方法分析了野生唇鲮Semilabeo notabilis（12尾）肌肉中的营养成分，其体质量为（215．24±80．41）g。结果表明：唇鲮的含肉率为（75．64±4．16）％，肌肉（鲜样）中水分、粗蛋白、粗脂肪和灰分的质量分数分别为（76．31±0．71）％、（17．06±0．84）％、（1．51±0．084）％和（1．72±O．25）％。肌肉中含有17种氨基酸，氨基酸的总质量分数为（82．45±O．90）％（占肌肉干重），其中含7种人体必需氨基酸，总量为（34．09±0．39）％，占总氨基酸总量的41．35％；4种鲜味氨基酸的质量分数为（31．26±0．37）％（占肌肉干重），占氨基酸总量的37．92％；必需氨基酸指数为72．79。脂肪酸中EPA与DHA含量较高，分别为（4．21±0．27）％、（3．64±0．22）％，表明唇鲮具有较高的食用价值与保健作用。

Evaluation of nutritive quality and nutritional composition of muscle in Semilabeo notabilis

Nutritional components in the muscle of Semilabeo notabilis （wet weight of 215.24g ± 80.41 g） were tested and analysed with routine methods. Samples of 12 wild individuals were collected from Dabang river in Guizhou Province in November of 2008. The fish had the dressed rate of （75.64 ± 4.16）%. There were （76.31 ±0.71 ） % of moisture, （ 17.06±0.84） % of crude protein, （ 1.51 ~ 0.084） % of crude fat and （ 1.72 ~ 0.25 ） % of crude ash in the muscles. In dry matter, the total content of 17 amino acids was found （82.45 ± 0.90）%, including （34.09 ± 0.39） % of essential amino acids, 41.35 % in total amino acids, and （31.26 ± 0.37） % of four delicious amino acids comprising of 37.92% in the total amino acids. The essential amino acid index （EAAI） was 72.79, and the contents of EPA and DHA in fatty acids were （4.21±0.27） % and （3.64±0.22） %, indicating that Semilabeo notabilis is one of the freshwater fishes with good edibility and nutritive value.
