摘要: The present invention relates to a process for separating 1-methoxypropan-2-ol in a stream S3 from an aqueous stream comprising 1-methoxypropan-2-ol and 2-methoxypropan-1-ol, wherein the process comprises providing a stream S0 comprising 1-methoxypropan-2-ol, 2-methoxypro-pan-1-ol and water, and having a molar ratio of 1-methoxypropan-2-ol:2-methoxypropan-1-ol in the range of from 1:5 to 5:1. A further aspect of the invention also relates to 1-methoxypropan-2-ol obtained or obtainable from said process, as well as to a mixture of 1-methoxypropan-2-ol and 2-methoxypropan-1-ol, preferably obtained or obtainable from said process, which preferably comprises in the range of from 95 to 100 weight-% 1-methoxypropan-2-ol and ≤0.5 weight-% of 2-methoxypropan-1-ol, each based on the total weight of the mixture.

摘要: 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.
