Reaction between ozone and colorants present in raw sugar leads to color elimination, without affecting sucrose or reducing sugars. In that sense, the use of ozone as decolorizing agent has great opportunities in the field of sugar refining. The refined sugar obtained by this method has a quality which fulfill the international requirements established. In preliminary economic evaluation, ozone can substitute advantageously other methods traditionally employed. Source: 2nd International Symposium on Ozone Applications Havana, Cuba - Mach 24-26, 1997.
