Process for the preparation of mixtures enriched in alpha-D-glucopyranosyl-(1-6)-D-sorbitol or alpha-D-glucopyranosyl-(1-6)-D-mannitol from hydrogenated isomaltulose.

摘要

Preparation of 1-O- alpha -D-glucopyranosyl-D-mannitol (1,1-GPM) and/or a 6-O- alpha -D-glucopyranosyl-D-sorbitol (1,1-GPS) enriched phase comprises a) solution of hydrolysed isomaltulose or a mixture containing hydrolysed isomaltulose in water at elevated temperature, b) crystallisation by cooling and c) separation of the phase containing 1,1-GPM (I) from 1,1-GPS (II).
