Activated Carbon is used as a decolorizing agent in the refining process for cane sugar as well as in the purification of sweeteners derived from corn, chicory and wheat. Corn starch is typically converted to various dextrose equivalent sugars by acid or enzymatic hydrolysis. High fructose corn syrup (HFCS) is made by the enzymatic isomerization of dextrose to fructose.
Activated carbon is also used for the treatment of fats and oils such as sunflower, soybean and rapeseed oils to remove colour or contaminants like polyaromatic hydrocarbons (PAH). Activated carbon in beverage include treatment of beer, wine and fruit juices.
