摘要
对山药多糖提取工艺进行优化,得出较佳提取条件应用于山药多糖的提取。实验以山药多糖收率为指标,对山药预处理时间,提取过程中提取温度、提取时间、物水质量比及提取次数,重复性,回收溶剂再利用等因素进行了考察。结果表明:山药多糖的较优提取工艺为预处理时间(2+2)h,提取时间2 h,提取温度60℃,物水比1∶20,提取次数1次;这样的提取工艺操作重复性好,溶剂回收再利用可行。
The optimization experiment of active polysaccharide extraction of Chinese yam was carried out and the optimal extraction condition was determined, which has been used in extracting of Chinese yam polysaccharide. In the experiment yam polysaccharide yield was taken as an index, yam pretreatment time, extraction temperature, extraction time, material-water mass ratio and extraction times, repeatability, recovery and reuse of solvent in the extraction process were studied. The results showed that the better pretreatment time for yam polysaccharide extraction is （2＋2） h, extraction time is 2 h, extraction temperature is 60 ℃, material-water ratio is 1 ： 20, extraction times is 1; repeatability for extraction operation is good, recycling solvents are feasible.
