摘　　要：为了解斧文蛤的营养成分及其营养特点,对养殖短文蛤和野生斧文蛤肉的营养成分进行了分析比较.结果显示,斧文蛤比短文蛤含有更多的蛋白质、糖类和灰分,2种文蛤均含有丰富的呈鲜、甜味氨基酸和人体必需氨基酸;与短文蛤相比,斧文蛤含有更多的谷氨酸、甘氨酸、赖氨酸,以及更高的必需氨基酸/总氨基酸(EAA/TAA)、必需氨基酸/非必需氨基酸(EAA/NEAA)比例,斧文蛤中苏氨酸,色氨酸的氨基酸评分值高于短文蛤;斧文蛤比短文蛤的脂肪含量低,但斧文蛤含有更多的不饱和脂肪酸.可见斧文蛤是一种营养丰富、味道鲜美的贝类,值得进行大规模养殖.To better understand the nutritional ingredients and nutritional characteristics of Meretrix lamarkii, the nutrition composition of meat sampled from Meretrix petechialis and Meretrix L. is analyzed and then compared. The results show that the content of protein, carbohydrate and ash in Meretrix L .are higher than those in Meretrix P..These two types of clam are found to contain rich fresh, sweet amino acid and essential amino acid. Compared with Meretrix P., Meretrix L. contain more glutamic acid, glycine, lysine, and a higher proportion of EAA/TAA, EAA/NEAA. The AAS value of Thr, Trp in Meretrix L. are higher than those in Meretrix P..The fat content in Meretrix L. is lower than those in Meretrix P., but the meat of Meretrix L. contain more unsaturated fatty acids. Conclusion can be made that Meretrix L. is a type of delicious shellfish rich in nutrition, and worth cultivating on large-scale.
