检测了闽南 -台湾浅滩渔场六种主要中上层鱼类 (蓝圆、金色小沙丁鱼、鲐鱼、颌圆、竹鱼、羽鳃鲐 )鱼肌的生化组成 ,蛋白质含量为 16 .94%～ 18.77% ,脂肪含量为 2 0 .12 %～ 2 5 .15 %。随鱼体体长的增加 ,脂肪含量增长。鱼肌脂肪含量与繁殖活动存在密切相关的季节变动。鱼肌中均含 17种氨基酸 ,必需氨基酸占总氨基酸的 45 .2 5 %～ 49.39% ,极性氨基酸占 42 .82 %～ 45 .16 % ,非极性氨基酸占 39.2 4%～ 41.5 9% ,鲜味氨基酸占 42 .5 6 %～ 46 .0 2 %。The biochemical composition of muscle were examed in six pelagic fishes(Decapterus maruadsi,Sardinella aurita,Pneurmatophorus japonicus,Decapterus lajang,Trachurus japonicus,Rastrelliger kanagurta).The protein content of muscle is 16.94%-18.77%,the lipid content is 20.12%-25.15%.With the increase of body length,lipid content increases.There is apparently relationship between the lipid content of muscle and reproductive activities.17 amino acids in muscle were detected,the percentage of the essential amino acids in total amino acids contents is 45.25%-49.39%,the polar amino acids,nonpolar amino acids and tasty amino acids in muscle are 16%,39.24%-41.59%,42.56%-46.02% respectively.国家教委海洋与环境开放研究实验室资助项目!
