摘要
对超滤技术纯化大豆糖蜜中的低聚糖进行了研究,探讨了pH和温度对膜分离效果的影响,确定超滤的较优条件为:选用截留相对分子量为10000的膜,pH7.0,温度20℃,采用间断全过滤的操作方式。在此条件下超滤所得的透过液澄清透亮,大分子类蛋白可完全去除,低聚糖透过率达70%。
Purification of oligosaccharide from soy molasses by ultrafiltration was studied. The effect of pH and temperature on ultrafiltration characteristic of the pretreated soy molasses was discussed. The optimum conditions were： 10000 molecular weight cut - off membrane, pH 7.0, 20℃, using discontinuous filtration operating mode. Under these conditions,the UF permeate was clear and bright, almost all of the macro - protein was removed, and about 70% of the oligosaccharide was retained.
