【摘要】 采用生化分析方法对闽江马口鱼(Opsariichthys bidens)肌肉常规营养成分和氨基酸(AA)组成与含量进行测定和分析，为闽江马口鱼的资源开发利用提供参考。结果表明：在闽江马口鱼肌肉的常规营养成分中，其水分、粗蛋白、粗脂肪和粗灰分含量依次为(75.20±0.14)%、(22.20±0.85)%、(3.15±0.02)%和(1.32±0.01)%;肌肉中检测出17种氨基酸，其中7种人体必需氨基酸(EAA)占氨基酸总量(TAA)的35.92%,鲜味氨基酸(UAA)占TAA的35.46%;EAA的氨基酸评分值(AAS)除了(Met+Cys)外均大于1.0,化学评分值(CS)除(Met+Cys)外均大于0.8,第一限制性氨基酸为(Met+Cys),必需氨基酸指数(EAAI)达到81.37;肌肉中微量元素含量从高到低依次为钾>磷>钙>钠>镁>锌，其中钙磷比为1.00∶4.49。综上，闽江马口鱼的营养价值较高，是一种具有良好食用价值和保健作用的优质经济鱼类。更多还原

【Abstract】 In order to provide scientific basis for the nutritional evaluation of Opsariichthys bidens muscle in Min River, the contents of routine nutrition components, fatty acids and amino acids in muscle were determined and analyzed by biochemical method.The results showed that the contents of water, crude protein, crude fat and crude ash in O.bidens muscle from Min River were(75.20±0.14)%,(22.20±0.85)%,(3.15±0.02)% and(1.32±0.01)%,respectively.17 kinds of amino acids were detected in muscle, 7 of which were human essential amino acid, accounting for 35.92% of total amino acids(TAA)and 35.46% of umami amino acids(UAA)in TAA.The amino acid score(AAS)of EAA was more than 1.0 except Met+Cys, the chemical score(CS)was more than 0.8 except Met+Cys, the first limiting amino acid was Met+Cys, and the essential amino acid index(EAAI)was 81.37.The content of trace elements in muscle from high to low was K>P>Ca>Na>Mg>Zn, of which the calcium-phosphorus ratio was 1.00∶4.49.To sum up, the O.bidens from Min River was a kind of high quality economic freshwater fish with good edible value and health care function.更多还原
