A pulverulent crystalline maltitol composition, is characterized in that it has a laser volume mean diameter between 10 and 150 &#x3bc;m; in that it has a maltitol content between 80 and 99.9% by weight; in that at least 50% by weight of its particles flow through a sieve having a cut-off threshold of 2000 &#x3bc;m according to a test A1; in that at least 35% by weight of its particles flow through a sieve having a cut-off threshold of 2000 &#x3bc;m according to a test A2; and in that it includes from 0.1 to 20% by weight of at least one water-insoluble anti-caking agent, the anti-caking agent having a hygroscopicity, determined according to the test B, between 2.5 and 25%. This composition is not subject to caking, and finds applications in the food and pharmaceutical fields.

Disclosed is a powder composition of mannitol crystals, produced by: (i) the crystallization of mannitol in a solvent; followed by (ii) a step of separating the crystals from the resulting crystal suspension; (iii) a step of drying the crystals; and (iv) a selection step, the composition having a particle size distribution, as determined by laser particle sizing, of 72 to 99.9 vol % of particles having a particle size greater than 75 &#x3bc;m, of 0.1 to 60 vol % of particles larger than 250 &#x3bc;m, and a mean diameter of between 100 and 300 &#x3bc;m. Also described is a method for producing such a composition by a step of crystallizing a mannitol syrup followed by drying the mannitol crystals, a step of selecting particles, and a step of collecting a fraction of the powder composition including 72 to 99.9% of particles having a particle size greater than 75 &#x3bc;m.
