摘要
为普安银鲫的推广养殖或其他基础研究提供参考依据,应用生化分析方法对普安银鲫A型鱼的肌肉营养成分进行了定量分析。结果表明:普安银鲫A型鱼肌肉中水分为(78.28±0.15)%,粗蛋白含量为(16.79±0.30)%,粗脂肪含量为(0.74±0.02)%,粗灰分含量为(0.98±0.05)%。普安银鲫A型鱼肌肉中含有17种氨基酸,总量为20.08%,必需氨基酸总量为8.21%,必需氨基酸与总氨基酸比值为40.89%,必需氨基酸与非必需氨基酸比值为69.19%,其必需氨基酸的构成比例符合FAO/WHO标准;脂肪酸中的EPA与DHA含量分别为0.48%和2.15%。普安银鲫A型鱼是一种高蛋白、低脂肪、氨基酸含量丰富、味道鲜美、营养价值高的养殖鱼类。
In order to provide reference for developing animal industry or other basic researches of Carassius auratus.In this paper,the nutritive composition in muscle of C.auratus（A form） was quantitatively analyzed by biochemical method.The results showed that water content was（78.28±0.15）%,crude protein content was（16.79±0.30）%,crude fat content was（0.74±0.02）%,crude ash content was（0.98±0.05）%.The muscle of C.auratus（A form） consisted of 17 kinds of amino acids,the gross amount was 20.08%,and the gross amount of essential amino acids was 8.21%.The ratio of the essential amino acids to the total amino acids was 40.89%.The ratio of the content of the essential amino acids to that of the non-essential amino acids was 69.19%.The proportion of the essential amino acids was in accordance with the standards of FAO/WHO.The contents of EPA and DHA in fatty acids were 0.48% and 2.15% respectively.This research indicated that C.auratus（A form） was a kind of cultured fishes,which had high protein,low fat,abundant amino acids,delicious taste and high nutritive value.
