Beschreibung
Zusammenfassung:	The present invention relates to a method for concentrating aqueous solutions of human milk oligosaccharides, in which an aqueous solution comprising at least one human milk oligosaccharide is subjected to a reverse osmosis process by means of a reverse osmosis membrane and is thereby concentrated to a final osmotic pressure of at least 70 bar measured with a freezing point osmometer. Moreover, the present invention refers to an according use of a reverse osmosis membrane, a corresponding reverse osmosis system containing such a membrane and a spray-dried HMO product obtainable by the method. La présente invention concerne un procédé de concentration de solutions aqueuses d'oligosaccharides du lait maternel, selon lequel une solution aqueuse comprenant au moins un oligosaccharide du lait maternel est soumise à un processus d'osmose inverse au moyen d'une membrane d'osmose inverse et est ainsi concentrée à une pression osmotique finale d'au moins 70 bars mesurée avec un osmomètre à point de congélation. De plus, la présente invention concerne une utilisation d'une membrane d'osmose inverse, un système d'osmose inverse correspondant contenant une telle membrane et un produit HMO séché par atomisation pouvant être obtenu au moyen dudit procédé.
