ABSTRACT:
The invention concerns a process for the preparation of crystallised maltulose monohydrate, characterised in that it comprises the steps of preparing an aqueous maltulose solution of a strength above 65% by weight, concentrating the aqueous maltulose solution to a dry matter ratio of more than 50% by weight and at a temperature such that the degree of maltulose supersaturation is less than 1, cooling the concentrated solution so as to take the degree of maltulose supersaturation to a value above 1, crystallising the maltulose in said supersaturated solution by cooling it at a controlled speed and by stirring, obtaining the separation, recuperation and drying of the maltulose monohydrate crystals.
