花鳗鲡鱼体肌肉的氨基酸分析研究

为了探讨不同体重花鳗鲡鱼体肌肉氨基酸的营养功效，指导消费者合理消费。本研究比较了不同体重（A组：360~420 g；B组：250~300 g；C组：200~250 g）花鳗鲡肌肉蛋白质的氨基酸组成，并分析了其必需氨基酸、呈味氨基酸、药效氨基酸含量。结果表明：花鳗鲡肌肉含有18种氨基酸，氨基酸总量分别达14.40%、18.30%、18.16%，谷氨酸含量最高。不同组别花鳗鲡的8种人体必需氨基酸含量高低顺序一致，占氨基酸总量的比例分别41.60%、41.63%、41.63%，呈味氨基酸的分布依次为甜味类氨基酸含量（A组：6.91%；B组：8.73%；C组：9.37%）、苦味类氨基酸含量（A组：5.46%；B组：6.96%；C组：6.94%）、酸味类氨基酸含量（A组：3.71%；B组：4.87%；C组：4.87%）、鲜味类氨基酸含量（A组：3.22%；B组：4.22%；C组：4.19%），药效氨基酸的分布依次为C组：12.56%、B组：11.93%、A组：9.33%。根据分析结果，本研究认为花鳗鲡鱼体肌肉蛋白是一种药食两用、氨基酸全面、肉质鲜美的优质蛋白，建议如以常规滋补兼顾口味为目的，以250~300 g的体重为宜；如以药用为目的，则选用200~250 g较好。

Amino Acid Analysis of Anguilla Marmorata Muscle

In order to explore the nutritional efficacy of Anguilla Marmorata Muscle in different sizes,and assist person taking reasonable consumption concept,the amino acid composition model in Anguilla marmorata with different sizes（3 groups：A：360-420 g;B：250-300 g;C：200-250 g） were analysed.The results showed that Anguilla marmorata muscle content 18 kinds of amino acids,the proportion of them were 14.4%,18.30% and 18.16% in group A,B,C separately.The contents of Glu was the highest in all groups.And the order of essential amino acid and EAA/TAA was similar in 3 groups.The contents of amino acid with different function in 3 groups were as followed：sweetness amino acids（A：6.91%,B：8.73% C：9.37%）,bitterness amino acids（A：5.46%,B：6.96%,C：6.94%）,tartness amino acids（A：3.71%,B：4.87%,C：4.87%）,delicious amino acids（A：3.22%,B：4.22%,C：4.19%）,drug-effective amino acids（A：9.33%,B：11.93%,C：12.56%）.The conclusion was that Anguilla marmorata was a aquatic product having medicine and food function.And Anguilla marmorata with body weigt 250-300 g have better food function,the ones with body weigt 200-250 g have better medicine function.
