Abstract
A novel method for making palatinitol comprising a first step of epimerising isomaltose under conditions enabling a mixture of &agr;-D-glucopyranosyl-(1→6)-D-mannose and isomaltose to be achieved, a second step of catalytically hydrogenating the mixture, and a third step of chromatographically depleting the isomaltitol in the hydrogenated mixture to give a roughly equimolecular mixture of &agr;-D-glucopyranosyl-(1→6)-D-sorbitol and &agr;-D-glucopyranosyl-(1→6)-D-mannitol.
