摘要
采用水浴法和微波辅助法对金针菇下脚料多糖的提取工艺进行了研究。实验结果表明,水浴料液比、提取温度和提取时间对金针菇下脚料多糖提取率有显著影响,优化的水浴提取工艺条件为料液比1:20,提取温度为80℃,提取时间2.0h,提取率达13.68%;微波提取料液比、微波功率和微波时间对金针菇下脚料多糖提取率有显著影响,优化的微波提取工艺为料液比为1:25,微波功率320W,微波提取时间80s,提取率达13.80%。与传统的水浴法相比,微波提取法效率高、节约能源,应用前景广阔。
The extraction conditions of polysaccharides from Flammulina velutipes off cuts by microwave and hot water were studied.The results showed that ratio of material to solvent, extraction temperature, extraction time of hot water method had significant effect on extraction yield and optimized conditions were 1：20,80℃,2.0h.Ratio of material to solvent, microwave power, extraction time of microwave method had significant effect on extraction yield and optimized conditions were 1 ：25,320W,80s.Under optimal conditions,the extraction yield was up to 13.68% and 13.80%, respectively.Microwave extraction was more efficient than hot water method and had a extensive future.
