Abstract

Currently, the sugarcane industry is becoming increasingly competitive, which in fact is encouraged mainly by the representative and demand requirements of foreign markets , especially with regard to crystal sugar and ethanol. When analyzing the production chain of white sugar, one can find barriers to its wide international acceptance, since this product has been associated with potential public health problems. Since 1 in every 100 people is sulfite -sensitive, and may have feelings of discomfort in the throat, hypotension, cough, etc. This problem happens due to the widespread use of sulfitation as a method of clarification of white crystal sugar, which brings to Brazil the need to develop new technologies and processes to ensure greater food security for white sugar available to the consumer. In this sense, about five years, the research group Hugot-Bioenergy has conducted studies on the implications of adopting new technologies to replace the sulfitation, without changing the quality of white sugar to be produced by gathering the patterns of acceptance of food and consumer industry. Given the assumption, this research project aims to evaluate the use of hydrogen peroxide business solution (35 % m / m) as an alternative reagent to sulfur dioxide to obtain white sugar with less ICUMSA color and analyze the chemical impacts microbiological and when used for reduction ICUMSA color in samples of syrup VHP sugar, as it has been used in Brazilian mills.
