Granted: 2014-01-20
Abstract: Galacto-oligosacáridos derivados de lactulosa multifuncionales con actividad inmunomoduladora y prebiótica.#La presente invención reivindica el carácter multifuncional de unos galactooligosacáridos derivados de la lactulosa (GOS-Lactulosa) empleando modelos in vivo (ratas Wistar) e in vitro utilizando líneas celulares intestinales de origen humano (Caco-2 y HT29-MTX) validadas como modelo de epitelio intestinal. Las ventajas principales derivadas del uso de este producto son múltiples y de gran valor añadido: propiedades prebióticas mejoradas y adicionales a las de los prebióticos comerciales utilizados habitualmente. Este producto se obtiene bien mediante la transgalactosilación directa de la lactulosa empleando una {be}-galactosidasa procedente de Aspergillus oryzae, o bien mediante la transgalactosilación de la lactosa y posterior isomerización química. Los GOS-Lactulosa objeto de la patente podrían ser descritos como prebióticos de segunda generación y, por tanto, de alto valor añadido y superior al de los prebióticos convencionales ya comercializados como la lactulosa o los GOS derivados de lactosa.
