中文摘要：
利用常规分析方法对鄱阳湖克氏原螯虾肌肉的营养成分进行测定,结果表明：肌肉中水分含量79.59％,粗蛋白含量18.70％,粗脂肪含量0.98％,粗灰分含量1.24％.钙含量443mg/100 g干重,磷含量1 200.00mg/100g干重.氨基酸总量83.32％（色氨酸因酸解破坏）,必需氨基酸含量28.25％,占氨基酸总量的33.91％,4种鲜味氨基酸的总含量为31.86％.必需脂肪酸含量14.38％,脂肪酸含量以C16∶0和C18∶1为最丰富,比例分别为21.50％和21.59％；EPA和DHA含量分别为9.17％和1.86％.脂肪酸中饱和脂肪酸（SFA）比例为33.59％,单不饱和脂肪酸（MUFA）比例为30.27％,多不饱和脂肪酸（PUFA）比例为25.58％.鄱阳湖克氏原螯虾是一种高蛋白低脂肪、营养丰富的淡水产品,值得大力推广养殖.
英文摘要：
Nutritional components of muscle of Procambraus clarkii in P＇o-yang lake were determined using conventional analysis methods.The results showed that the contents of moisture,crude protein,crude fat and crude ash of the fresh muscles were 79.59 ％,18.70 ％,0.98 ％ and 1.24 ％,respectively.The contents of calcium was 443mg/100 g and phosphorus 1 200.00 mg/100 g （dry weigh）.The total amino acid was 83.32％（Tryptophan was damaged in acidolysis）.The amount of essential amino acid was measured to be 28.25％,which was 33.91％ of total amino acid.The content of four tasty amino acids was 31.86％.The percentage of essential fatty acid was 14.38％.C16∶ 0 and C18∶1 were the most abundant fatty acids,whose proportions were 21.50％ and 21.59％ respectively.EPA and DHA contents were respectively 9.17％ and 1.86％.SFA,MUFA and PUFA of fatty acid were found to be 33.59％,30.27％ and 25.58％ respectively.Procambraus clarkii in Poyang lake,which contained high protein and low fat,could be a kind of eutrophy freshwater product and worthy breeding vigorously.
