for conventional sugar refineries processing raw sugar for more than 2000 ICUMSA color and producing white refined sugar of less than 30 color, adsorbent-based decolorization is
an essential process stage. white refining processes such as affination and clarification remove significant amounts of color from the raw sugar being processed, an additional color removal step is needed ahead of the final crystallization stage to ensure that the white sugar product always meets the product color specification.
