| 摘 要： | 对乐清湾泥蚶(Tegillarca granosa)肉营养成分进行了分析。结果表明，乐清湾泥蚶肉(干基)粗蛋白含量为67．75％；蛋白质氨基酸评价为85．4分，色氨基酸是惟一的限制性氨基酸。在蛋白质氨基酸组成中。以呈鲜味、甘味或与之有关的谷氨酸、冬氨酸、丙氨酸、甘氨酸、脯氨酸、丝氨酸6种氨基酸含量最高，占氨基酸总量的46．71％；不饱和脂肪酸含量也相当高．尤其是高度不饱和脂肪酸C20：5(EPA)和C22：6(DHA)，占脂肪酸总含量的31．62％；此外还含有多种人体必需的维生素、无机盐、微量元素等多种成分。

| Abstract: | The nutritional compositions of meat of clam, Tegillarca granosa in Yueqing Bay were analyzed. The content of crude protein was 67.75%(DW); The protein nutrient value was high and the score of amino acids was 84, the only limiting amino acid was Trp. The tasty amino acids such as Glu, Asp, Ala, Gly, Pro and Ser was rich in the edible protein, accounting for 46.7% of all amino acids. Polyunsaturated fatty acid C20:5(EPA) and C22:6(DHA) were rather rich with the content accounting for 31.62% of all fatty acids. Other nutrients such as Vitamin,mineral and microelements were quite rich. |
