Abstract
A process for producing a solid material comprising isomaltulose crystals and trehalulose, including: A) contacting an enzyme complex with a sucrose-containing solution; B) isomerizing at least a part of the sucrose to isomaltulose and trehalulose; C) separating off the enzyme complex to obatin a solution including isomaltulose, trehalulose and water; D) partially removing the water by evaporation to obtain a concentrated solution; E) bringing the concentrated solution to a temperature range of 30° C. to 63° C. and subsequently inducing isomaltulose crystallization in this temperature range followed by cooling, thereby obtaining a solid material including isomaltulose crystals and trehalulose.
