Mill scale evaluation of hydrogen peroxide as a processing aid: quality improvement in plantation white sugar

摘要

The authors have previously demonstrated the utility of hydrogen peroxide as an effective bleaching agent for raw juice, clarified juice and syrup. The mill scale trials described here further demonstrate the utility of the reagent in reducing the non -sugars contents of the treated products and consequent improvement in their quality. Thus, in addition to 12-35/100 colour reduction, 17-21/100 reduction in polyphenols, 15-24.6/100 reduction in amino acids, 12-13/100 reduction in polycacchraides and 15 -22/100 reduction in SO_2 content in the treated products was observed when hydrogen peroxide was used during sugar production.
