Patent ID: 8012263

Claim:
Process for preparing maltitol crystals by evapocrystallization, wherein the process comprises: a) preparing a maltitol solution with a maltitol richness of at least 85% based on dry matter, b) concentrating said maltitol solution under vacuum in an evapocrystallizer so as to obtain a maltitol syrup whose degree of maltitol supersaturation is within the metastable zone of maltitol, c) seeding the maltitol syrup with a maltitol seed crystal in dispersed form, d) performing the evapocrystallization while keeping constant the degree of maltitol supersaturation within the metastable zone of maltitol by controlling the conditions of temperature, conditions of vigorous stirring by pumping evaporation vapors, and conditions of feeding in of the maltitol syrup to be crystallized, and e) recovering crystals thus obtained.
