Estudio del efecto enzimático, térmico y fotoquímico en la transformación de la vainillina

Abstract

El objetivo del presente trabajo fue estudiar los mecanismos de transformación de la vainillina en soluciones modelo por efecto enzimático, térmico y fotoquímico. Se prepararon soluciones de vainillina en una solución buffer de fosfatos pH 5 y fueron expuestas a efecto enzimático por la actividad de la peroxidasa, térmico en un reactor a 200 °C y 15 bar durante 90, 180, 270 y 360 min y fotoquímico mediante luz LED blanca durante 1, 4, 7, 14, 21, 28 días. Las soluciones fueron analizadas mediante RMN y GC-MS. Los resultados indicaron que el efecto enzimático por peroxidasa genera mayor transformación de la vainillina, produciendo su dímero (divainillina) hasta un 97%. Por otra parte, el efecto térmico presenta hasta un 11.15% de transformación de la vainillina, produciendo divainillina, 3,3'-dimetoxibifenil-4,4'-diol y otros fragmentos. Mediante fotoquímica no se identificaron los cambios químicos en la vainillina solo cambios de color, al no identificar nuevos compuestos.

Keywords
