          Abstract

          El orujo de la industria vitivinícola, actualmente representa un problema de gestión de residuos debido a su alta carga de contaminación; sin embargo, es fuente de elementos funcionales, etanol y compost. Se fermentó el orujo por dos veces, tras los cuales se cuantificaron por triplicado los fenólicos totales y flavonoides. El líquido obtenido en conjunto, se destilaron en sistemas diferencial y optimizó con rectificación. Posteriormente se compostó el orujo con tres réplicas, a los cuales se aplicaron microorganismos eficientes autóctonos. Los fenólicos totales son significativamente diferentes entre primera y segunda fermentación, en tanto que los flavonoides no tienen diferenciación significativa. Los parámetros de optimización para los grados alcohólicos fueron; sistema de reflujo, potencia de calefacción y caudal de flujo de agua para condensado, obteniéndose 81.47 grados alcohólicos. El tiempo de compostaje duró 21 días, menor que otros métodos. Estos resultados reflejaron, la importancia de explotación del orujo como fuente alimentario, energético y agrícola.

          The pomace of the wine industry currently represents a waste management problem due to its high pollution load; however, it is a source of functional elements, ethanol and compost. Pomace was fermented twice, after which total phenolics and flavonoids were quantified in triplicate. The liquid obtained together, was distilled in differential systems and optimized with rectification. Subsequently, the pomace was composed with three replicates, to which efficient natives microorganisms were applied. Total phenolics are significantly different between first and second fermentation, while flavonoids have no significant differentiation. Optimization parameters for alcoholic degrees were; reflux system, heating power and water flow rate for condensate, obtaining 81.47 alcoholic degrees. The composting time lasted 21 days, shorter than other methods. These results reflected the importance of pomace exploitation as a food, energy and agricultural source.
