摘　　要：糊精是妨碍麦芽糖结晶和晶浆过滤的主要因素。从精制超高麦芽糖浆中除去糊精的有效方法之一是固定床色谱分离法。通过实验研究,证实色谱分离法可以有效地除去糊精,麦芽糖的单程收率可达50%,浓缩糖浆的结晶速度加快,晶浆过滤变得相对容易。结晶麦芽糖的纯度超过98%。Maltodextrin is a main negative factor to the crystallization process of maltose.Fixed bed chromatographic separation is an effective approach to get rid of maltodextrin from refined ultra-high content maltose syrup.It is proved in this paper that dextrin can be removed through such a process,its single-pass yield being 50%.This resulted in faster crystallization and easier centrifugation.And the crystallized maltose reached a purity of over 98%.
