摘　　要：采用泡沫分离法纯化亚麻胶中的酸性多糖。以料液浓度、原料液pH值、装液量以及泡沫分离温度为单因素进行正交试验,得出泡沫分离的最佳工艺条件为:料液浓度是180μg/mL,pH值为3,装液量300 mL,温度为20℃。在该条件下酸性多糖的富集比为9.0,回收率达到82.4%。研究结果表明:采用泡沫分离技术可以实现亚麻胶中酸性多糖和中性多糖的分离,是酸性多糖和中性多糖初级分离的一种有效方法。A foam fractionation method was employed to purify acidic polysaccharides. The effects of the operational factors, i.e. initial feed concentration, pH of raw solution and the volume of liquid and the temperature of foam separation of acidic polysaccharides have been investigated. On the basis of single factor test and orthogonal experiment, it was found that the optimum condition of foam separation was initial feed concentration of 180 μg/mL, pH of 3, volume of liquid of 300 mL, temperature of 20 ℃. Under this condition, the protein removal rate reached 82.4%, protein enrichment ratio reached 9.0. The as-obtained results show that it is an effective method to separate neutral polysaccharides from acidic polysaccharides using foam separation.
