(54) Title: PROCESS FOR PRODUCTION OF A SOLID MATERIAL CONTAINING ISOMALTULOSE CRYSTALS AND TRE- HALULOSE IN (57) : The present invention provides a process for production of a solid material containing isomaltulose crystals and trehalu- © lose 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 1-1 by evaporation, while obtaining a concentrated solution with, based on the total solution, a solid content of 75 wt% to 95wt%, preferably 80wt% to 93wt%, particularly preferably 86 wt% to 92 wt%; E) bringing the concentrated solution to a temperature of 30 °C to 63 1-1 °C, preferably 45 °C to 62 °C, even more preferably 55 °C to 60°C, and subsequent induction of isomaltulose crystallisation in this ei temperature range followed by cooling while obtaining a solid material containing isomaltulose crystals and trehalulose.
