    摘要: Micronized polyols having a particle size distribution (d50) of from 20 to 60 μm, and a flowability below or equal to 5 s/100 g, preferably below 5 s/100 g, are disclosed. The micronized polyols, although they have a smaller particle size distribution compared to the corresponding milled polyols, have improved flowability. Most preferably, the polyol is one or more of maltitol, isomalt, mannitol, sorbitol, xylitol and erythritol. Preferred polyols also demonstrate a compressibility index (%) of not less than 40. The process for micronizing a polyol comprises the steps of a) taking a polyol having the chemical formula CnH2n+2On and which is solid at 20 to 25° C., b) feeding the polyol into a jet mill and applying pressure using nitrogen and c) collecting the micronized polyol. The micronized polyols are useful in food, feed, cosmetic and pharmaceutical compositions, especially chewing gum compositions.
