摘要：目的研究无机陶瓷微滤膜纯化虫草粗多糖溶液，确定操作工艺条件和有效清洗方法。方法主要考察膜通量和膜通量恢复率。结果在60℃，pH7～8、0．3～0．4MPa压差操作条件下微滤虫草粗多糖溶液，多糖收率较传统醇提工艺高出30％，同时可除去大部分不溶固体物和蛋白质胶体等大分子有机物杂质。采用80℃热水与1％NaOH溶液交替清洗并伴有间歇、短时反冲洗，可使膜的清水通量恢复率达到90％以上。结论无机陶瓷微滤膜纯化虫草粗多糖溶液工艺简单、可行。
Objective To apply the membrane technology for purifying rough cordyceps polysaccharides solution, the optimal operation condition and effective cleaning method were researched. Methods To mainly analyze the flux of membrane and its recovery. Results The optimal experiment operation condition obtained is 60℃, pH value 7-8, and pressure 0.3-0.4 MPa, by which the polysaccharides recovery was about 30%, more than by traditional ethanol extraction, and the most impurities as infusibility substance and protein colloid etc. were taken out. Moreover, the flux of membrane recovery can be above 90% after 80℃ water and 1 % NaOH solution was alternately used to wash the fouling membrane under intermittent little back-pulsing. Conclusion The process of membrane technology purifying rough cordyceps polysaccharides is simpl and feasible.
