Avaliação do efeito da irradiação micro-ondas no caldo de cana-de-açúcar como tratamento preliminar para produção de açúcar e etanol

Abstract

The use of non-thermal irradiation technologies such as microwave may simplify the process of sugarcane juice clarification. Thus, the aim of this study was to purify sugarcane juice by microwave radiation in order to produce sugar and ethanol. The results were submitted to analysis of variance (ANOVA) followed by Tukey test with significance level 0.05. As regards the original and processed material it was analyzed for: turbidity, color, total soluble solids (Brix) and pH, as well as microbiologically. The results showed that the microwave in the tested conditions did not promote the sugarcane juice clarification and, also, it had a significant increase in ° Brix.
