Several processes have been developed over the years to attain efficient and cost-effective removal of colour in order to produce low colour white sugars. These low colour sugars are now a popular quality raw sugar for the increasing number of destination refineries. Appreciation of the types of colour present in raw sugar is important when choosing and operating refinery processes, as different processes may remove different types of colour bodies. Therefore, combinations of different processes are usually required to produce the best quality refined sugar. This paper reviews the mechanisms of colour removal of the major processes in the cane sugar refining industry, in terms of physical and chemical properties relating to the different colour bodies present. Also, the suggestions for optimum process combinations are presented.
