dc.description.abstractThe objective of this investigation was to use an ultrafiltration system in combination with the addition of sodium metabisulfite to try to solve the problems that the passion fruit schnapps presented. The effect of these treatments and the stability of the storage of the schnapps during three months were evaluated with an analysis of turbidity, color, sugars content and sensory analysis. The results show that using the membrane and adding 200ppm of sodium metabisulfite obtained a passion fruit schnapps of quality in terms of turbidity, color, aroma and flavor. Additional studies are required to be able to increase the flow of the membrane filtration process and to determine the optimal conditions of the process. Then, it could be included in the elaboration of schnapps and the product could be commercialized.

El efecto de estos tratamientos y la estabilidad del almacenamiento del cordial durante tres meses fueron evaluados con un análisis de color, turbidez, contenido de azúcares y un análisis sensorial. Los resultados muestran que al utilizar la membrana y al añadir 200ppm de metabisulfito de sodio se obtuvo un cordial de parcha de calidad en términos de turbidez, color, aroma y sabor. Se requieren estudios adicionales para poder aumentar el flujo del proceso de filtración con membrana y determinar las condiciones óptimas del proceso, de esta forma incluirlo como parte de la elaboración del cordial y poder comercializar el producto.
