  • Rectangular parallelepipedal maltitol
    Patent number: 9938313
    Abstract: The invention concerns maltitol crystals, characterized in that they have a rectangular parallelepipedal shape and have a length to width dimensional ratio in the range 1.8 to 5.3, preferably 3±0.7, and a process for producing them.
    Type: Grant
    Filed: October 4, 2016
    Date of Patent: April 10, 2018
    Assignee: Roquette Freres
    Inventors: Manuel Barata, Pierrick Duflot, Abdelfattah Bensouissi, Mohamed Mathlouthi

  • Process for the evapocrystallization of maltitol
    Patent number: 8012263
    Abstract: A process for preparing maltitol crystals by evapocrystallization, includes preparing a maltitol solution with a maltitol richness of at least 85% based on dry matter, preferably a maltitol richness of between 89% and 99% based on dry matter, and even more preferably a maltitol richness of between 93% and 95% based on dry matter; concentrating under vacuum maltitol solution in the evapocrystallizer so as to obtain a maltitol syrup whose degree of maltitol supersaturation is within the metastable zone of maltitol; seeding the supersaturated maltitol solution with a maltitol seed crystal in dispersed form; performing the crystallization while keeping constant the degree of maltitol supersaturation within the metastable zone of maltitol by controlling the conditions of temperature, the conditions of vigorous stirring by pumping of the evaporation vapors, and the conditions of feeding in of the maltitol syrup to be crystallized; and recovering the crystals thus obtained.
