摘　　要：制糖工艺过程出现的右旋糖酐(Dextran)是由细菌感染(蔗糖转化)形成,它的存在意味着糖分损失,糖液粘度增大,对制(炼)糖生产造成危害,降低糖分收回和产品质量。本文综述了制糖工业中右旋糖酐的检测方法,以及国内外学者对不同方法的比较研究,并对该研究领域进行展望。样品中右旋糖酐的分子量大小及分布是影响测定结果的重要因素。制糖物料或产品中的右旋糖酐分子量大小以及分布对制糖过程的影响、不同检测方法对不同分子量右旋糖酐的响应等问题将成为今后的研究方向。Dextran appeared in the process of sugar production is formed by bacterial infection(sucrose conversion).The presence of dextran in sugar juice means severe sugar loss?increased viscosity of the sugar flow?harmful impact of sugar production and sugar refinery,reduced sug-ar recovery,and declined quality of sugar.This paper reviewed the methods of dextran detec-tion in sugar industry,and the comparative studies of different methods at home and abroad?prospected the future picture of this field.The molecular weight and its range of dextran in samples were important factors for the results.The molecular weight and its distribution of process materials and products?effects of dextran with different molecular weight on sugar pro-duction,and the response of different methods to different molecular weight?would be the re-search direction in the future.
