阳江乐清两地泥蚶肌肉组织营养成分研究

研究结果表明，泥蚶肌肉中含有氨基酸和脂肪酸各18种，氨基酸总含量平均为42．76mg／g，其中必需氨基酸占氨基酸总量的36．17％，呈鲜味和甘味游离氨基酸占氨基酸总量的50．42％；脂肪酸总含量平均为25．86mg／g，其中不饱和脂肪酸占脂肪酸总量的48．88％。统计分析表明，两个地区相比较，阳江泥蚶肌肉中的氨基酸和脂肪酸总含量更为丰富，但乐清泥蚶肌肉的营养结构更佳，营养价值更为突出。

Fatty Acids and Amino Acids in Muscular Tissue of Mud Clam Tegillarca granosa Linnaeus from Two Different Regions

Amino acid and fatty acid levels were determined and compared in muscular tissue of mud clam Tegillarca granosa Linnaeus collected from Yang-jiang,Guangdong Province and Yue-qing,Zhejiang Province.Eighteen kinds of amino acids and fatty acids were found in the muscle,total contents being 42.76 mg/g and 25.86 mg/g,respectively.The total contents of essential amino acids and flavor amino acids reached 15.47 mg/g and 20.78 mg/g,about 36.17% and 50.42% of the total amino acids.There were total monounsaturated fatty acid(MUFA) and polyunsaturated fatty acid(PUFA) contents of 7.29 mg/g,about 58.60% of the total content of fatty acids.There were more amino acids and fatty acids in the clam sampled from the Yang-jiang than those in the clam collected from Yue-qing which had a better structure of nutrition,and higher prominent nutritional values.
