Abstract
Glucopyranosido-1,6-mannitol, represented by the formula: ##STR1## and a process for its preparation are provided. The glucopyranosido-1,6-mannitol is obtained by catalytically hydrogenating neutral aqueous solutions of isomaltulose and cooling the hydrogenated solution. In a second embodiment of the invention the use of the glucopyranosido-1,6-mannitol as a sugar substitute, sweetener for food or beverages, and sweetened food composition is provided.
Claims3
A process for producing glucopyranosido-1,6-mannitol, comprising hydrogenating neutral aqueous solutions of isomaltulose having an isomaltulose content of greater than 50% by weight in the presence of a hydrogenation catalyst under a hydrogen pressure of from 30 to 100 kg/cm.sup.2 at a temperature of from 100.degree. to 130.degree. C. for a time sufficient to complete hydrogenation;
- thereafter cooling the hydrogenated solution to cause said glucopyranosido-1,6-mannitol to crystallize as a first substance from said solution and separating the glucopyranosido-1,6-mannitol from the resulting suspension.
