Abstract:
An organic solvent free process for the preparation of crystallized maltulose monohydrate comprising the steps of:preparing an aqueous maltulose solution of a strength greater than about 65% of maltulose by weight;concentrating said aqueous maltulose solution to a dry matter ratio of greater than about 50% by weight of maltulose and at a temperature such that the degree of maltulose supersaturation is less than 1;cooling said concentrated aqueous maltulose solution to increase maltulose supersaturation to a value above 1;crystallizing the maltulose monohydrate in said supersaturated aqueous maltulose solution by cooling it at a controlled speed and by stirring; and p1 collecting the maltulose monohydrate crystals formed from said supersaturated aqueous maltulose solution and subsequently drying said crystals.
