Otimização dos processos de obtenção de açúcares redutores totais (ART) a partir do bagaço de abacaxi

Abstract

With the growing and competitive demand for ethanol in relation to fossil fuels, a new challenge has arisen on the world scene: to increase production without increasing the planted area, thus avoiding competition for space with other food crops, a case in which the proposal of second generation ethanol fits. In this sense, this work aimed to analyze the performance of pineapple bagasse as a possible biomass for the production of second generation ethanol. The stage of enzymatic hydrolysis was evaluated, aiming at the highest obtainment of TSA (Total Reducing Sugars). It was verified through data analysis that the highest values of ART are obtained for the lowest concentrations of peroxide along with the lowest temperatures and the shortest reaction times. It is also observed that using all variables at their highest levels the worst ART response is obtained. We observed that in both studied granulometries of the bagasse, 20 and 48 mesh, responses for the enzymatic hydrolysis were obtained, very close in their profile.
