Process for the purification of xylooligosaccharides based on the use of diafiltration.

摘要

Process for the purification of xylooligosaccharides.; The present invention, entitled "Process for the purification of xylooligosaccharides", claims a procedure for the purification of xylooligosaccharides obtained by hydrolytic degradation (chemical and / or enzymatically) from the hemicellulose fraction of vegetable biomass in aqueous medium. Hydrolysis liquors containing xylooligosaccharides along with other unwanted components, which must be removed to allow the use of xylooligosaccharides for food. This object is achieved by diafiltration (possibly in combination with other physicochemical operations described in the application text nature). the use of the fractions containing xylooligosaccharides purified as food ingredients with prebiotic properties, applicable in human nutrition and animal nutrition claimed.
