| 摘 要： | 对罗氏沼虾选育新品种——“南太湖2号”与非选育群体的肌肉营养成分及营养品质进行了分析比较。研究结果表明,罗氏沼虾“南太湖2号”肌肉中粗灰分含量与非选育群体差异不显著(P>0.05),蛋白质含量显著高于非选育群体(P＜0.05),肌肉粗脂肪和水分含量显著低于非选育群体(P＜0.05)；“南太湖2号”和非选育群体的氨基酸组成基本一致,均测定出含有17种氨基酸,其构成比例符合联合国粮农组织/世界卫生组织(FAO/WHO)的标准。“南太湖2号”的总氨基酸含量、必需氨基酸含量和鲜味氨基酸含量均显著高于非选育群体(P＜0.05),根据氨基酸评分(AAS)和化学评分(CS)计算结果,第一限制性氨基酸均为异亮氨酸；“南太湖2号”肌肉中多不饱和脂肪酸(PUFA)、二十碳五烯酸(EPA)及二十二碳六烯酸(DHA)的总量分别为41.34%?0.54%和28.09%?0.45%,显著高于非选育群体(P＜0.05)；ω3PUFA含量显著高于非选育群体(P＜0.05),而ω6PUFA含量差异不显著(P>0.05)。实验结果说明,罗氏沼虾“南太湖2号”的营养品质明显优于非选育群体。

| Abstract: | A comparison study of the muscle nutritive composition and quality between the new selected strain of Macrobrachium rosenbergii,South Tailake No.2and the non-selected population was carried out.The results showed that there was no significant difference of the crude ash content between theSouth Tailake No.2and the non-selected population(P > 0.05).The muscle crude protein of theSouth Tailake No.2was significantly higher than that of the non-selected population(P < 0.05),and muscle crude fat and moisture wer... |
