Abstract
A novel method for making palatinitol comprising a first step of epimerising isomaltose under conditions enabling a mixture of .alpha.-D-glucopyranosyl-(1.fwdarw.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 .alpha.-D-glucopyranosyl-(1.fwdarw.6)-D-sorbitol and .alpha.-D-glucopyranosyl-(1.fwdarw.6)-D-mannitol.
