摘　　要：对贻贝属的两种有经济价值的种类——紫贻贝和厚壳贻贝的蛋白质、氨基酸、不饱和脂肪酸、无机元素等营养成分进行了研究。通过分析比较发现厚壳贻贝的蛋白质、粗脂肪含量高于紫贻贝,必需氨基酸含量二者差别不十分明显,但厚壳贻贝的谷氨酸、甘氨酸、天冬氨酸含量明显高于紫贻贝,所以厚壳贻贝的海鲜味较浓。厚壳贻贝的二十二碳六烯酸(DHA)含量高于紫贻贝。厚壳贻贝的多不饱和脂肪酸明显高于单不饱和脂肪酸,而紫贻贝的两种不饱和脂肪酸含量相差不大。除铝、硒外,其它12种无机元素厚壳贻贝都明显高于紫贻贝。In this paper the four indexes of two mussels-Mytilus edulis and Mytilus coruscus were measured. The four indexes were protein, amino acids,unsaturated fatty acids and inorganic elements. The contents of protein and crude fats in Mytilus coruscus were higher than those in Mytilus edulis. The contents of essential amino acids have no difference between the two mussels. Mytilus coruscus is a heavy seafood,as there are much more glutamic acid, glycine and aspartic acid in it. The content of docosahexenoic acid (DHA)in M. coruscus was much more than that of M. edulis. Except for Aluminium and Selenium,the other 12 kinds of elements in M. edulis were higher than those in M. coruscus. The contents of polyunsatu-rated fatty acids(PUFAs) were much more than those of monounsaturated acids (MUFAs)in M. coruscus. There is little difference of the content between PUFAs and MUFAs in M. edulis.
