摘要
试验旨在研究鄱阳湖流域野生和养殖翘嘴鳜(SiniPerca chuatsi)肌肉营养成分.选择鄱阳湖流域野生和养殖翘嘴鳜各30尾,检测肌肉常规成分、氨基酸、脂肪酸、矿物质含量.结果显示,野生样本肌肉中水分含量显著高于养殖样本(P<0.05),粗蛋白和粗脂肪含量显著低于养殖样本(P<0.05).野生和养殖翘嘴鳜肌肉中氨基酸种类相同,野生样本肌肉中组氨酸含量(0.34%)显著低于养殖样本(0.36%)(P<0.05).鄱阳湖流域野生和养殖翘嘴鳜鱼氨基酸组成均符合FAO/WHO标准.野生样本肌肉中C20:5n3(EPA)含量(1.33%)显著高于养殖样本(0.34%)(P<0.05),C22:6n3(DHA)含量(2.66%)显著高于养殖样本(1.10%)(P<0.05).野生样本硒含量(0.45mg/kg)显著高于养殖样本(0.23 mg/kg)(P<0.05).研究表明,鄱阳湖流域野生和养殖翘嘴鳜的肌肉氨基酸组成较为接近,营养价值较高,翘嘴鳜在养殖环境下各项营养指标基本媲美野生样本.
Abstract
This study aimed to investigate the nutritional components of the muscle in wild and farmed Siniperca chuatsi from the Poyang Lake basin.A total of 30 wild and 30 farmed Siniperca chuatsi from the Poyang Lake basin were selected and the contents of conventional components,amino acids,fatty acids,and minerals in muscle were detected.The results showed that the moisture content in the muscle of the wild samples was significantly higher than that of the farmed samples(P<0.05),while the crude protein and crude fat content were significantly lower than those of the farmed samples(P<0.05).The types of amino acids in the muscle of wild and farmed Siniperca chuatsi were identical,with the histidine content in the muscle of the wild samples(0.34%)being significantly lower than that of the farmed samples(0.36%)(P<0.05).The amino acid composition of the muscle in both wild and farmed Siniperca chuatsi from the Poyang Lake basin met the FAO/WHO standards.The EPA content in the muscle of the wild samples(1.33%)was significantly higher than that of the farmed samples(0.34%)(P<0.05),and the DHA content(2.66%)was significantly higher than that of the farmed samples(1.10%)(P<0.05).The selenium content in the muscle of the wild samples(0.45 mg/kg)was significantly higher than that of the farmed samples(0.23 mg/kg)(P<0.05).The study indicates that the muscle amino acid composition of wild and farmed Siniperca chuatsi from the Poyang Lake basin is quite similar,both possessing high nutritional value,and that the nutritional indicators of Siniperca chuatsi in the Poyang Lake basin under farming conditions are essentially comparable to those of the wild samples.
