What is decolorizing carbon?

Decolorizing carbon is finely produced activated carbon, which is often used to decolorize a solution. The small particles of decolorizing carbon provide a large surface area to which large colored molecules may become adsorbed.

The following is some cases used in food industry.

Sugar decolorization

Sugar products are made of cassava as raw material, and produced into monosaccharide solution through enzyme and water electrolysis.Some factories use hydrochloric acid and water electrolysis to produce monosaccharide solutions. The biggest difference is that yellow pigment is produced by the hydrochloric acid method. The color is darker than the enzymatic method, HMF latent pigment, so activated carbon not only decolorizes, but also removes HMF and Fe.


For sucrose decolorization, clients will choose derun specialized activated carbon. It uses low-ash, low-sulfur bituminous coal as raw material and adopts advanced grinding and remodeling briquetting technology. It is usually used in sugar purification industry. Derun can add MgO for a highly efficient and stable magnesium oxide activated carbon for sugar decolorization.

Citric acid

Citric acid is an organic acid. The pigments in the acid are red and yellow. Derun activated carbon can remove gum, protein, and decolorize.


Palm oil produces diesel by-product glycerin during the production of biodiesel. Our activated carbon can remove the macromolecular pigment and the fat that has not been completely removed during the glycerin purification process.
