摘　　要：为探究江西省不同地区细鳞鲴肌肉营养组成及品质差异,以江西省内4个地区捕捞的野生细鳞鲴(215.30±19.29 g)为研究对象,通过常规生化分析对其肌肉的常规营养成分、氨基酸和脂肪酸进行比较分析。结果显示,各地区细鳞鲴肌肉水分、粗蛋白和粗灰分含量均无显著差异(P>0.05),湘东区和峡江县肌肉粗脂肪含量显著高于余干县(P<0.05)。湘东区肌肉色氨酸显著高于其他各组(P<0.05),总氨基酸、必需氨基酸和呈味氨基酸含量在各组之间无显著差异(P>0.05);根据AAS评分,进贤县和峡江县缬氨酸、湘东区苯丙氨酸和酪氨酸为第一限制性氨基酸;根据CS评分,各地区苯丙氨酸和酪氨酸为第一限制性氨基酸。余干县C18:1含量显著高于其他3个地区(P<0.05),余干县和峡江县C18:3(亚麻酸)含量显著高于进贤县和湘东区(P<0.05),各地区DHA/EPA和n-3/n-6均无显著差异(P>0.05)。综上所述,本研究中4个地区细鳞鲴肌肉具有较高的营养价值,营养成分差异不大,为今后细鳞鲴人工养殖饲料的配制提供依据。This study was conducted to investigate the differentiation of flesh nutrition composition and quality in different areas of Jiangxi province.The wild Xenocypris microlepis(215.30±19.29 g)caught in four areas of Jiangxi province were taken as the research object,and the conventional nutritional composition,amino acids and fatty acids of their flesh were compared and analyzed by routine biochemical analysis.The results showed that there was no significant difference in moisture,crude protein and crude ash of flesh among different regions(P>0.05),but crude lipid of flesh in Xiangdong and Xiajiang county was significantly higher than that in Yugan county(P>0.05).The tryptophan of flesh in Xiangdong county was significantly higher than that in other groups(P>0.05).There was no significant difference in the other 17 amino acids,total amino acids,essential amino acids and delicious amino acids content among different groups(P>0.05).According to AAS score,valine score was the lowest in Jinxian county and Xiajiang county,and phenylalanine and tyrosine were the first limiting amino acid in Xiangdong.According to CS score,phenylalanine and tyrosine were the first limiting amino acid in each region.The content of C181 in Yugan county was significantly higher than that in other three areas(P>0.05).The content of C183 in Yugan county and Xiajiang county was significantly higher than that in Jinxian county and Xiangdong district(P>0.05).There was no significant difference in DHA/EPA and n-3/n-6 among different regions(P>0.05).To sum up,there was little difference in the flesh with high nutritional value in four areas,which provides a scientific basis for the configuration of artificial culture diet in the future.
