摘　　要：本文对浙江沿海不同种群缢蛏进行了氨基酸及脂肪酸分析。结果表明,缢蛏富含人体生命活动所需的各种必需氨基酸、不饱和脂肪酸等营养物质。不同种群缢蛏氨基酸组成及含量呈现出比较一致的变化,各种群呈味氨基酸含量都比较高,达到50%;脂肪酸组成及含量未呈现出一致的变化,单不饱和脂肪酸(SUFA)以奉化养殖种群最高;多不饱和脂肪酸(PUFA)以长街养殖种群最高;(EPA+DHA)含量以乐清养殖缢蛏最高;(亚油酸+亚麻酸)以长街野生种群最高。A comparative study on the amino acid and fatty acid in the meat of Sinonovacula constricta was conducted among different populations in zhejiang sea areas. The results showed that all the populations contain essential amino acids, unsaturated fat ty acids.The variety of amino acid in different populations is accordant. All the populations contain many delicious amino acids（ 50% ）.The constitutes and contents of fatty acid did not have the same diversification in different populations.The content of SUFA of Fenghua farmed populations are higher than others; The content of PUFA of Changjie farmed populations are higher than others; The content of EPA and DHA of Yueqing farmed populations are higher than others; While the content of sub-oleic acid and linolenic acid of Changjie wild populations are higher than others.
