摘要
利用常规肌肉营养测定方法,分析了微山湖四鼻须鲤(Cyprinus carpio)野生群体和养殖群体各10尾的肌肉营养成分。结果显示,四鼻须鲤野生群体的粗蛋白(18.05%)和钙(0.69mg/g)含量高于养殖群体的17.27%和0.49mg/g,野生四鼻须鲤的粗脂肪含量(1.02%)低于养殖群体(1.86%),两者的水分、粗灰分和磷含量基本相同,肌肉中氨基酸组成基本一致,均含有18种氨基酸,4种呈味氨基酸总量分别为6.71%和6.08%(鲜样),必需氨基酸指数(EAAI)分别为73.35和67.44,其构成比例符合FAO/WHO的标准。
The muscle nutrition composition of 10 wild carps and 10 cultured Cyprinus carpio in Weishan Lake in Jiangsu Province were analyzed.The results showed that the contents of crude protein(18.05%)and calcium(0.69 mg/g)of wild fish were higher than those of cultured fish.The levels of crude fatty acid of wild fish(1.02%)were lower than cultured ones(1.86%),the contents of water content,crude ash and phosphorus were not significantly different between wild and farmed carps.The composition of amino acids of wild ...
