A process for producing phases enriched with 1,1-GPM (1-O-.alpha.-D-Glucopyranosyl-D-mannite) and/or 1,6-GPS (6-O-.alpha.-D- Glucopyranosyl-D-sorbite), from hydrogenated isomaltulose or mixtures containing hydrogenated isomaltulose. The latter is dissolved in water at an elevated temperature, the resulting solution is crystallized by cooling the solution over a predetermined temperature range sufficient to obtain the desired phase composition, and the phase enriched with 1,1-GPM is subsequently separated from the phase enriched with 1,6-GPS.

Méthode pour obtenir des phases enrichies en 1,1-GPM (1-O-alpha-D-glucopyranosyl-D-mannite) et (ou) en 1,6-GPS (6-O-alpha-D- glucopyranosyl-D-sorbite), à partir d'isomaltulose hydrogéné ou de mélanges qui en renferment. Celui-ci est dissous dans l'eau à température élevée; la solution résultante est cristallisée en refroidissant la solution dans une plage de température présélectionnée, suffisante pour obtenir la composition phasique recherchée; la phase enrichie en 1,1-GPM est ensuite séparée de la phase enrichie en 1,6-GPS.
