Abstract

The invention relates to a process for producing mixtures selectively enriched with either 1,1-GPM and 1,6-GPS from hydrogenated isomaltulose. The process involves dissolving hydrogenated isomaltulose at an elevated temperature, and subjecting the resulting solution to one or more cooling steps, wherein each cooling step utilizes a predetermined cooling rate over a predetermined temperature range.
