【摘要】 采用微波协助提取山药低聚糖,在单因素试验的基础上对微波功率、乙醇浓度、料液比和微波处理时间进行正交试验,结果显示,影响山药低聚糖提取率的因素主次顺序为乙醇浓度,微波处理时间,料液比,微波功率,微波协助提取山药低聚糖的最佳工艺条件为微波功率130W,乙醇体积分数为60%vol,料液比为1∶30(g∶mL),微波处理时间6min。更多还原

【Abstract】 The microwave extraction and measurement of oligosaccharide from Chinese Yam was studied.According to the single factor experiment,the optimal condition for extracting oligosaccharide was obtained through orthogonal test: extraction power 130W,extraction time 6min,the ratio of solid to 60%vol ethanol 1∶30(g∶ml).The order of affecting the factors was ethanol volume fraction,extraction time,the solid to liquid ratio and microwave power.更多还原
