Main components of ash in white granulated sugar was determined in this paper, and then the variation laws of these given ash components were analyzed by lab experiments and industrial production during sulfitation process to find the main reasons of causing high ash content in white granulated sugar, which could provide theory for sugar mills in decreasing ash content of white granulated sugar.%分析灰分超标白砂糖灰分成份,并通过试验室模拟试验与分析主要灰分成份在澄清过程变化,探讨白砂糖灰分超标的主要原因,为糖厂降低白砂糖灰分提供理论依据.
