Crystallization of glucopyranosylalditols, crystalline glucopyranosylalditol product and use thereof

摘要

The invention relates to a novel process for the crystallization of glucopyranosylalditols selected from the group consisting of 1-O- alpha -D-glucopyranosyl-D-mannitol (1,1-GPM), 6-O- alpha -D-glucopyranosyl-D-sorbitol (1,6-GPS) and 1-O- alpha -D-glucopyranosyl-D-sorbitol (1,1-GPS). The process is performed by contacting a glucopyranosylalditol solution with particulate glucopyranosylalditol(s) suspended in a gas, drying the material to produce a multitude of microcrystals and conditioning the material into an agglomerated product. The invention also relates to a particulate crystalline glucopyranosylalditol product having novel properties, to the use thereof in confectionery, foodstuffs, pharmaceuticals and oral hygiene products, and to special products comprising the same.
