실험 절차

In the process according to the invention, the depletion of the epimerized mixture in isomaltose is, on the contrary, carried out in such a manner as to obtain a fraction containing a roughly equimolecular proportion of isomaltose and α-D-glucopyranosyl-(1→6)-D-mannose, the other fraction being constituted by very pure isomaltose. By roughly equimolecular is meant from 40 to 60% and more preferably from 45 to 55% of one of the two compounds relative to the total mass of the two compounds. This way of proceeding has the advantage of directly obtaining a mixture which after hydrogenation will provide the two components of palatinitol, namely isomaltitol and GPM in roughly equimolecular proportions, without having to resort to remixing pure fractions.
