摘　　要：利用传统营养分析方法对细点圆趾蟹和锯缘青蟹的肌肉营养成分进行研究。结果表明:两种海蟹共检测出18种氨基酸,细点圆趾蟹和锯缘青蟹的必需氨基酸占总氨基酸的比例分别为37.83%和34.32%,构成比例均符合联合国粮农组织、世界卫生组织的评价标准;细点圆趾蟹肌肉必需氨基酸指数(EAAI)为59.80,而锯缘青蟹则为68.27,比前者营养价值稍高;两种海蟹的第一限制性氨基酸均为缬氨酸,细点圆趾蟹和锯缘青蟹脂肪酸中前者的饱和脂肪酸含量为22.97%,要显著高于后者的16.64%;多不饱和脂肪酸均以EPA为主,EPA+DHA含量分别为17.90%和11.75%。两种海蟹的锌含量均较高,且Zn/Cu均明显小于10,是较好的锌元素补充源食物;细点圆趾蟹也是较好的硒元素食物来源。研究表明,两种海蟹均具有较高营养价值,同时二者的一些营养成分也存在着差异。Muscle nutrients of Ovalipes punctatus and Scylla serrata were studied by general nutritional test.The results showed that the ratio of essential amino acids to total amino acids in the muscles of Ovalipes punctatus and Scylla serrata were 37.83%and 34.32% respectively in 18 amino acids of those two kinds of crab,and their proportions were both in accordance with the evaluation criteria of United Nations Food and Agriculture Organization World Health Organization. The essential amino acid index( EAAI) of the muscle of Ovalipes punctatus was 59.80,while that of Scylla Serrata was 68.27,which hod higher nutritive value than Ovalipes punctatus.The first restrictive amino acids in the muscle of Ovalipes punctatus and Scylla serrata were both valine.The content of saturated fatty acids in the muscle fatty acids of Ovalipes punctatus was 22.97%,which was significantly higher than that of Scylla serrata( 16.64%). Polyunsaturated fatty acids were mainly EPA,and the total content of EPA and DHA were 17.90% and 11.75%,respectively. The content of Zn was abundant in two kinds of crabs with the ratio of Zn to copper significantly less than 10,indicating that the two were good sources of Zn supplement food.Ovalipes punctatus was also a good source of Se supplement food.The researches showed that both two kinds of sea crabs had high nutritional value,and there were also differences in some nutrients between them.
