Estudio comparativo del fraccionamiento de los carbohidratos de la miel mediante tratamiento con carbón activo y levaduras para la detección de adulteraciones

Abstract

Recientemente se ha descrito la utilidad de los anhídridos de difructosa (DFAs) como buenos marcadores para la detección de adulteraciones de miel con jarabes de alto contenido en fructosa (HFCS) y de azúcar invertido (IS). Sin embargo, para la detección de estos compuestos es necesario realizar un fraccionamiento previo de los carbohidratos de estas muestras, dado que la alta concentración de monosacáridos (glucosa y fructosa) presentes en la miel dificulta el análisis de los compuestos minoritarios. Por tanto, el objetivo de este trabajo se basó en la comparación de un tratamiento con levaduras propuesto con anterioridad y un fraccionamiento con carbón activo para eliminar la fracción de monosacáridos, concentrando así los compuestos minoritarios de la miel y en concreto los DFAs presentes en muestras adulteradas. Se llevó a cabo la optimización de dichos métodos para conseguir el mayor enriquecimiento en DFAs comprobándose que ambos son útiles para la detección de adulteraciones de miel de hasta un 5% de HFCS e IS.
