Abstract
The present invention relates to a granulated sorbitol of essentially γ crystalline form and having a high sorbitol content, characterized in that it has a specific surface area, determined according to the BET method, of greater than or equal to 2 m2/g, preferably of between 2.2 and 4 m2/g, and even more preferably of between 2.5 and 3.5 m2/g, a compressibility of between 200 and 400 N, preferably of between 250 and 350 N, and a volume-average diameter, measured by laser diffraction particle sizing using a dry-system module, of between 260 and 1000 μm, preferably of between 260 and 500 μm, and even more preferably of between 260 and 350 μm.
