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.
