摘　　要：3 葡聚糖的测定方法 3．1 常用的测定方法 3．1．1 酒精Haze法及改进后的酒精Haze法 1959年Nicholson和Horsley根据葡聚糖溶液中加入酒精后产生沉淀，然后用分光光度计测量所产生沉淀浊度的原理提出Haze法测定葡聚糖含量。国际糖品统一分析方法委员会（ICUMSA）在第十七届会议上把此法列为试行方法。Dextran formed by Leuconostoc mesenteroides in sugar cane and beets causes processing difficulties that lead to loss of recoverable sucrose. This loss of efficiency has a significant financial impact on sugar factory operations. This paper reviews the negative influence of dextrans to sugar industry, the main causes of their formation, the measures of their prevention, the ways of their removal, and the methods of their detection.
