摘要
以猕猴桃果为原料,利用超滤膜装置对浸提的猕猴桃果多糖进行分离。同时对超滤过程的阻力及传质特性进行分析,并建立超滤过程的修正凝胶极化模型。经过实验获得猕猴桃果多糖提取率5.7%,多糖质量分数89.2%,表明利用超滤方法分离浓缩猕猴桃果多糖是有效的工艺手段。
The separation of Polysaccharides extracted from Chinensis Actinidia Fruit by Ultrafiltration Membrane is tested. The resistance and mass transfer property of ultrafiltration are analyzed, and the modified model of gelatification and polarization is established for the ultrafiltration process. A purity of 89.2% and a yield of 5.7% of Chinensis Actinidia polysaccharides are achieved in optimized conditions, which shows that the ultrafiltration is an efficient method to separate and concentrate water soluble Chinensis Actinidia polysaccharides.
