Sugar Refining

Activated carbon is used in raw and refined sugar decolorisation — removing colour compounds (melanoidins, caramels, and polyphenols) from sugar liquors as a modern bone-char replacement. High decolorisation efficiency and consistent mesh sizing are critical for column operations.

How It Works

The process, step by step

Liquor preparation

Raw sugar is dissolved to form a liquor. The liquor is pre-treated to remove suspended solids before carbon contact.

Carbon contact

Sugar liquor passes through GAC columns or is mixed with PAC. Colour compounds adsorb onto the carbon surface.

Filtration & polishing

Decolorised liquor is filtered, then evaporated and crystallised. Colour (ICUMSA units) is measured at each stage.
