Process for production of a solid material containing isomaltulose crystals and trehalulose

Abstract

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 % to 95 wt %, preferably 80 wt % to 93 wt %, particularly preferably 86 wt % to 92 wt %; E) bringing the concentrated solution to a temperature of 30° C. to 63° C., preferably 45° C. to 62° C., even more preferably 55° C. to 60° C., and subsequent induction of isomaltulose crystallisation in this temperature range followed by cooling while obtaining a solid material containing isomaltulose crystals and trehalulose.
