Other authors report that the removal of anthocyanins from sugar juice occurs by precipitation, which results from the excess calcium used during the carbonatation process (ARAUJO, 2007; CASTRO; ANDRADE, 2007).
The carbonatation of sugar cane juice consists in adding carbon dioxide concomitantly with calcium hydroxide, stabilizing its pH and forming the calcium carbonate complex, which acts as an agglutinating agent for the removal of substances diluted in the juice (HAMERSKI et al.
Therefore, as a contribution to studies dealing with the clarification of sugar cane juice by carbonatation, current investigation studied the influence of the addition of carbon dioxide and pH control on starch and ICUMSA color removal in the clarification of sugar cane juice.
In natura sugar cane juice was previously evaluated to compare and quantify the effect of the carbonatation process on its composition (Table 2).
