Abstract

The process of clarification of sugar has been the subject of several research in order to improve the quality of the sugar obtained from both the standpoint of new technologies in equipment and processes, how about the study of the physicochemical properties of sucrose during decomposition the clarification. Our laboratory Quality Control of Sugar and Alcohol has been working on an ample study on the technological impact of other oxidative processes, in addition to sulfitation, to reduce color in sugarcane juice to produce white sugar. Some methods have been proposed for the clarification of the juice, decanted juice or syrup, applying a variety of methods to obtain a final product with low color and turbidity, as referred to accepted standards of food industry and consumer. In this sense, the POA's (advanced oxidation processes) have been applied, in particular, ozonization of the juice, and this design is to propose an alternative to the conventional sulfitation of the juice to obtain the sugar white crystal, by using peroxide hydrogen as a reducing agent of the color of juice and the impact on generating possible toxic compounds.
