| 摘 要： | 测定分析日本对虾肌肉的营养成分,并与部分经济水产动物进行比较。结果表明:日本对虾含肉率为39.21%,水分和粗灰分含量分别为77.16%和1.79%,蛋白质和脂肪含量分别为17.74%和2.08%。肌肉(干样)中18种氨基酸总量(TAA)为70.68%,必需氨基酸指数(EAAI)为70.72,其构成比例低于鸡蛋蛋白标准,但高于WHO/FAO标准。根据氨基酸评分(AAS)和化学评分(CS)计算结果,得出日本对虾的第一限制性氨基酸为色氨酸,第二限制性氨基酸为缬氨酸。5种鲜味氨基酸(DAA)总量为35.71%(干样)。日本对虾不饱和脂肪酸含量较高,占脂肪酸总量的64.04%,其中二十碳五烯酸(EPA)、二十二碳六烯酸(DHA)分别为1.70%和10.92%,多不饱和脂肪酸和EPA、DHA含量高于其他几种经济虾类及淡水鱼类。铁和锌含量丰富,镉、铬、镍等有害元素含量低。表明日本对虾具有较高的食用价值与保健作用。

| Abstract: | The nutritional composition in the muscle of Penaeus japonicus was analyzed and compared with that of some high-quality shrimps,crabs and fish.The results showed that the contents of flesh,water,crude ash,crude protein and fat in P.japonicus were 39.21%,77.16%,1.79%,17.74% and 2.08%,respectively.Eighteen common amino acids were detected in the muscle of P.japonicus.In dry samples,the content of total amino acids(TAA) was 70.68%,in which the content of essential amino acids(EAA) was 23.25%.The essential amin... |
