Abstract

The study evaluated the ethanol production potential of four industrial cassava cultivars, considering the influence of harvest age and two glucose quantification methods on bioethanol yield. The research adopted an experimental and quantitative approach, analyzing glucose levels and enzymatic hydrolysis coefficients in samples harvested at 12 and 15 months. Two quantification methods were used: the Accu-Chek® Guide Me glucometer and calculations based on the hydrolysis coefficient. Results indicated that both harvest age and quantification method significantly affected ethanol yield, with higher glucose levels observed in samples harvested at 15 months and evaluated by the direct method. The BRS Formosa and BRS Mulata cultivars showed the highest potential for bioethanol production, standing out as promising alternatives in the bioenergy sector. The study concluded that the choice of cultivar, combined with the definition of ideal harvest age and the application of precise quantification methods, optimizes the bioethanol production process, making it more efficient and sustainable. These findings provided novel and practical data for cassava variety selection and contribute to the development of a more sustainable and economically viable production cycle.
