Complex processing steps that may introduce an off-color are often used in the manufacture of food products, chemicals and pharmaceuticals. Decolorisation is undertaken using ColorSorb activated carbon. Applications in the decolorization of food products include the processing of glucose and dextrose syrups, sugar refining, edible oil processing and wine treatment. Organic and inorganic acids including adipic, citric, lactic and phosphoric acid are often decolorized. In the pharmaceutical industry specialist applications exist requiring high purity activated carbons.
