微波辅助提取鸡油菌多糖的工艺研究

目的]筛选鸡油菌多糖的微波提取工艺。方法]试验以鸡油菌为原料,以水为提取剂,利用微波辅助提取鸡油菌中多糖。在单因素试验基础上采用正交试验研究提取时间、微波功率、料液比对鸡油菌中多糖提取效果的影响,以提取的多糖得率为指标,确定微波辅助提取鸡油菌中多糖的最优方案,并与热水浸提法比较。结果]影响鸡油菌中多糖提取效果的因素效应的主次顺序为微波功率〉料液比〉提取时间;最佳试验方案为微波功率400 W,提取时间9 min,料液比1∶25（g/ml）,此条件下鸡油菌多糖质量分数为13.55%。结论]与热水浸提法相比,微波辅助提取法提取效果好、多糖得率高,可用于鸡油菌多糖的提取。

Study on Microwave-assisted Extraction Technology of Polysaccharides from Cantharelles cibarius

Abstract Objective] The aim was to screen the microwave-assisted extraction technology of polysaccharides from Cantharelles cibarius.Method] Polysaccharides in Cantharelles cibarius was extracted by microwave-assisted extraction using Cantharelles cibarius as raw materials,water as extractant.Orthogonal design method was used to study the effect of extraction time,microwave power and solid to liquid ratio on extraction percentage of polysaccharides.The optimal extraction conditions were determined by usin...
