研究乙醇浓度、提取温度、提取时间、提取次数对魔芋葡甘聚糖得率的影响,通过正交试验优化乙醇沉淀法提纯魔芋葡甘聚糖的实验条件.结果表明:以90%的乙醇,在70℃温度下提取3次,每次3 h,可得到纯度为90.8%的魔芋葡甘聚糖,得率为78.5%.

The effect of ethyl alcohol density,extraction temperature,extraction time,as well as extraction number of times on the extraction rate of konjac glucanm-annan was studied in the paper.The optimized parameters was gotten by using the single factor and orthogonal design.It was shown that 90% ethyl alcohol,70 ℃,3 times and each time 3 h,the extraction rate of konjac g...
