PROCESO PARA LA PURIFICACION DE XILOOLIGOSACARIDOS BASADO EN EL EMPLEO DE LA DIAFILTRACION

Process for the purification of xylooligosaccharides based on the use of diafiltration. The present invention, entitled "process for the purification of xylooligosaccharides based on the use of diafiltration", claims a process applicable to the purification of xylooligosaccharides obtained by hydrolytic degradation (chemically and/or enzymatically) of the hemicellulosic fraction of plant biomass in aqueous medium. The hydrolysis liquors contain xylooligosaccharides together with other unwanted components, which must be eliminated to allow the use of xylooligosaccharides for food purposes. This objective is achieved through diafiltration (possibly, in combination with other physical-chemical operations that are described in the text of the application). The use of fractions containing purified xylooligosaccharides as food ingredients with prebiotic properties, applicable in human nutrition and animal feed, is claimed.
