Abstract
This study was evaluating the physicochemical parameters and polarization value of raw sugar which ultimately affect the filterability of raw sugar. Ten different raw sugar samples were collected from Brazil to the Hawamdia refinery sugar factory. The obtained results revealed that a high percentage of starch in raw sugar led to low Filterability during the dissolving of raw sugar to remove the molasses layer where it causes problems in the refined sugar process and increases the production cost. The ash contents were found to be decreasing for the samples of refined sugar compared to raw sugar. The values for the polarization were the highest in samples of refined sugar while the lowest values were in raw sugar samples. It can be concluded that raw sugar samples included low quality whereas samples of refined sugar were determined to be of a good grade. Raw sugar contained a high percentage of starch and color it was at a lower degree of purity, which is necessarily required to use the refining process to produce sugar with a higher degree of quality and purity, a low percentage of color and higher purity. Also, refined sugar contained a small mineral content and polyphenol fraction compared to raw sugar.
