摘要
介绍了对广西六家亚硫酸法糖厂２０００／０１年榨季不同时期、不同色值段的白砂糖中的铁和酚类物定量测定的结果。证明，这些白砂糖样品的色值小于１２０ＴＵ时，平均含铁量为０．７７ｐｐｍ，含酚量为３４ｐｐｍ；而色值为２００～２３０ＩＵ的白砂糖样品平均含铁量为１．４４ｐｐｍ，含酚量为５０ｐｐｍ．含铁量每增加０．０５８ｐｐｍ，或含酚量每增加２ｐｐｍ即可导致色值增加１０ＩＵ．同时对测定结果进行了分析付论．
An investigation was carried out on the iron and phenelics contents in the granulated white sugar produced by the sulphitation method varying with different periods of milling and different ranges of color values, the sugar was sampling from 6 sugar mills within the administrative region. It revealed that, for sugar with color value less than 120 IU, the mean iron content was 0. 77ppm and the phenelics conten34ppm; for sugar with color value between 200 to 230IU, the mean contents of iron was 144ppm and phenelics 50ppm, an increase of 0. 058 ppm of iron content or 2 ppm of phenelics content in the sugar was in an association with an increase of 10 IU in the color. The testing results were analyzed and discussed in detailed.
