摘要:
本研究在分析浸泡乙醇浓度、提取水浴温度、提取负压、提取时间等4个单因素对柞蚕雄蛾浓缩液提取得率影响的基础上,通过正交试验对4因素进行了优化,最终确定柞蚕雄蛾浓缩液最佳提取工艺条件为:95%食用酒精在水浴温度60℃、提取负压-0.09 MPa的条件下提取4 h。该提取工艺条件下柞蚕雄蛾浓缩液得率19.09%,浓缩液清澈透明、感观品质好、脂肪含量低,可直接加工成保健品服用或用于勾兑雄蚕蛾酒及饮料等。

AbstractBased on the effect analysis of 4 single factors including ethanol concentrate, water bath temperature, extracting negative pressure and time on the extraction rate, an orthogonal experimental was designed to optimize the extraction technology.The optimum extraction conditions were extracting for 4 hours with 95% ethanol (v/v) as solvent in 60℃ water bath and under –0.09 Mpa. Under the optimum conditions,the extraction rate was 19.09%,and the concentrated extract of tussah male moth was clear and transparent with better sensory quality and lower fat content,so it could be processed into tonic product directly or used to produce blended wine.

柞蚕产自山野,其雄蛾由雄蛹变态而来,个大体健,飞翔能力及求偶欲极强,属食疗珍品,国家卫生部已将蚕蛾列为有特定保健功能的动物性资源,雄蚕蛾当属其中极品,历史上曾被作为“贡品”,被誉为“神虫国宝”。柞蚕雄蛾是柞蚕4个变态中的成虫阶段,也是性成熟阶段,不再取食也不再生长,完成交配后就结束一生。此阶段柞蚕雄蛾体内积聚了大量能调节机体功能的营养物质,如矿物质、微量元素、维生素和激素类及其它活性物质,这些营养活性物质的存在使得柞蚕雄蛾具有一定的药用功效,可减轻氢化可的松所致的肾阳虚小鼠的阳虚症状,显示出雄性激素样作用和对肾阳虚的预防作用。
传统柞蚕雄蛾主要用来泡制药酒或配制中药,但随着科技发展,传统雄蚕蛾加工利用方式已不能适应便捷、高效的现代食品、药品加工工艺要求,为高效利用柞蚕雄蛾原料,推动蚕业资源多元化利用,笔者对柞蚕雄蛾营养物质的提取技术进行了研究。……
