SU A860-Ion exchange resin for cane sugar refining decolorization

In cane sugar refinery, there are some colorants which lead to a tan sugar. Most sugar colorants have an anionic nature, being charged negatively, strong base anionic resin (SUA500,A860,A420) are efficient decolorizers. SUA500 and SUA860 show higher efficiency than SUA420, but SUA420 have a low cost, so, some factories still select this resin for sugar decolorization.
