A COMPARISON OF ION EXCHANGE RESIN AND ACTIVATED CARBON IN THE APPLICATION OF SUGAR DECOLOURISATION

Both ion exchange resin and activated carbon are well established technologies used in the final stage decolourisation of sugar liquors for the production of high quality white sugars. These technologies have often seen to be in direct competition, but there are unique advantages and disadvantages to both, and are applicable in different circumstances. This paper attempts to clarify the distinction. The colour removal mechanism between these technologies differ, resulting in slightly different colour causing molecules being removed, and as such, have been used as complimentary processes.
