桑椹籽油提取工艺优选

Extraction Process of the Seed-Oil from Morus alba

目的:确定正己烷索氏提取桑籽油的最佳工艺。方法:将桑籽粉碎,用正己烷对桑籽油进行提取。以桑籽油提取率为指标,分别考察了浸提溶剂、回流温度、提取时间、溶剂倍量等因素对桑籽油提取率的影响,进行了工艺优化的正交设计,确定了桑籽油提取的最佳工艺。结果:对提取率影响主次次序为回流温度、提取时间、溶剂倍量。提取桑籽油最佳提取工艺为回流温度80℃,提取时间4 h,溶剂倍量(g∶mL)1∶24。桑籽油的提取率32.33%。结论:该工艺稳定、可行、节能,生产周期短,提取效率高,适于工业化生产。

Objective：To optimize the extraction process of the seed-soil from Morus alba L.by SoxhLet with hexane.Method： Crushed seeds from Morus alba,and extracted the seed-oil with hexane.Orthogonal design was used to optimize the extraction process of the seed-soil from Morus alba With the yield of seed-oil as index.Four factors were investigated to determine the optimum extraction process,which including extraction solvent,refluxing temperature,extraction time,solvent volume.Result： The order of factors which affected extracting was： refluxing temperature,extraction time,solvent volume.The optimum extraction process was to reflux the seeds at 80 ℃,extraction time was 4 h with 24 times amount of hexane.The extraction rate was 32.33%.Conclusion： The optimum extraction process is achieved,which is stable,feasible,energy-saving,short production cycle,high extraction efficiency,suitable for industrialization.
