Relação entre a concentração dos compostos fenólicos do mosto e a eficiência da fermentação alcoólica por subprodutos em processo contínuo

The objective of this work was to evaluate the relationship between phenolic compounds and alcoholic fermentation efficiency. The yield of sugarcanebyproducts (glycerol, acidity, and biomass) was determined in a continuous process at SaoManoel Sugarcane Mill, (Sao Paulo, Brazil) during the 2011/2012 harvest period. The Saccharomyces cerevisiae strain used as inoculum was the CAT-1. During the harvest, the endogenous yeast outcompeted the selected strain, hence eliminating it from the process. This research consists of a case of study on the ethanol production facility. FolinCiocauteau and methylene blue method was used to assess phenolic compounds. The efficiencyof the byproducts generated during the fermentation processwas calculated. Statistics analyses were carried out using Pearson correlation and its significance, by thet-test. We concluded that the phenolic compounds within the must could not be correlated to the byproducts’fermentation efficiency calculated during a continuous fermentation process.
