PROCESS FOR PRODUCTION OF A SOLID MATERIAL CONTAINING ISOMALTULOSE CRYSTALS AND TREHALULOSE

The present invention provides a process for production of a solid material containing isomaltulose crystals and trehalulose comprising the process steps A) bringing an enzyme complex which is able to catalyse the reaction of sucrose to isomaltulose and trehalulose into contact with a sucrose-containing solution; B) isomerizing at least some of the sucrose to isomaltulose and trehalulose; C) separating off the enzyme complex to give a solution containing isomaltulose, trehalulose and water; D) partial removal of the water by evaporation, while obtaining a concentrated solution with, based on the total solution, a solid content of 75 wt pcnt to 95wt pcnt , preferably 80wt pcnt to 93wt pcnt , particularly preferably 86 wt pcnt to 92 wt pcnt ; E) bringing the concentrated solution to a temperature of 30 øC to 63 øC, preferably 45 øC to 62 øC, even more preferably 55 øC to 60øC, and subsequent induction of isomaltulose crystallisation in this temperature range followed by cooling while obtaining a solid material containing isomaltulose crystals and trehalulose.
