Physico-Chemical Analysis and Polarization Value Estimation of Raw Sugar from Refining Point of View


This study was particularly designed to evaluate the physico-chemical parameters and polarization value of raw sugar which ultimately affect the filterability of raw sugar. Six different raw sugar samples were collected from the local industries and were evaluated for the physico-chemical and polarization value. The physico-chemical characteristics of sugar including moisture, reducing sugar, ash contents, size of crystals and color constituents were assessed. The results obtained from physico-chemical analysis showed that these parameters were affected significantly among the samples of raw sugar. The ash contents were found to be decreasing for the samples in the order of T6 > T1T2T5 > T3T4. The values for the polarization were significantly the highest in sample T5, T2 and T1 followed by sample T4 and T6 while the lowest values were recorded for sample T3. It can be concluded from the results that sample T4 was observed to have a good quality while sample T6 had the opposite result to that of sample T4 and was considered to have a very low quality.
