不同柞蚕品种鲜蛹营养组分检测及分析

Detection and Analysis of Nutritional Components in Fresh Pupae of Different Antheraea pernyi Varieties

[目的]选育适合在一化性柞蚕产区放养的优质、高产、蛹丝兼用的柞蚕新品种。[方法]对川柞1号、川柞2号、河33、贵101及通江这5个柞蚕品种鲜蛹的主要营养成分、氨基酸、维生素及微量元素锌、硒的含量进行检测分析。[结果]川柞2号鲜蛹营养组分综合表现最优,其中蛋白质质量分数为12.45%;粗脂肪质量分数为5.77%;氨基酸质量分数为9.71%,EAA/TAA为40.37%,EAA/NEAA为67.6%,药效氨基酸和支链氨基酸含量略高于其他品种,鲜味氨基酸仅次于贵101;维生素A、B 1、B 2、C、E及微量元素锌、硒含量较为丰富。[结论]川柞2号属优质蛋白质资源,适合在一化性柞蚕产区作为蛹丝兼用品种示范推广。

[Objective]The research aimed to breed a new Antheraea pernyi variety with high quality,high yield and pupa and silk dual-purposes in the univoltine Antheraea pernyi production area.[Method]The main nutrients,amino acids,vitamins and trace elements zinc and selenium in fresh pupae of five tussah varieties(Chuanzuo 1,Chuanzuo 2,He 33,Gui 101 and Tongjiang)were detected and analyzed.[Result]The nutritional composition of fresh pupae of Chuanxiong No.2 was the best,with protein content of 12.45%;crude fat mass fraction of 5.77%;amino acid mass fraction of 9.71%,EAA/TAA of 40.37%,and EAA/NEAA of 67.6%;the content of amino acid with medicinal function and branched-chain amino acid was slightly higher than other varieties,and the content of amino acid with flavor enhancement effect was only next to gui 101;vitamin A,B1,B2,C,E and trace elements zinc and selenium were relatively abundant.[Conclusion]Chuanxiong 2 is a high-quality protein resource,which is suitable for demonstration and promotion as a pupa and silk dual-purposes in the univoltine Antheraea pernyi production area.
