    摘要: A crystalline mixture solid containing maltitol having an oil absorptivity of 0.1 to 6.9 wt % and a bulk density of 0.60 to 0.75 g/cc when it is ground and classified to ensure that at least 70 wt % of the obtained particles should have a particle size of 16 to 50 mesh and a process for producing a crystalline mixture solid containing maltitol, comprising introducing air bubbles into a maltitol aqueous solution. According to this process, a crystalline mixture solid containing maltitol having high solubility and almost no moisture absorption is produced at a high work efficiency and a low cost in a short period of time.
