花鳗鲡鱼体肌肉的氨基酸分析研究

Amino Acid Analysis of Anguilla Marmorata Muscle

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:360～420g;B组:250～300g;C组:200～250g)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250～300g的体重为宜;如以药用为目的,则选用200～250g较好。

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.
