Method for producing a powder containing xylitol crystal particles with another polyol

Abstract

The invention relates to a method for producing a powder containing xylitol crystal particles and another polyol comprising a mixture containing a xylitol syrup and another polyol, whose dry material content is equal to or greater than 95 % by weight, xylitol content ranges from 85 to 97.5 % by weight and the other polyol content ranges at least from 15 to 2.5 % by weight with respects to the drymaterial, wherein the inventive method consists in obtaining said mixture by simultaneously dispersing the xylitol and the other polyol syrup and xylitol-containing germs in an open rotating vessel containing xylitol-based granules, in mixing the xylitol and the other polyol syrup and xylitol-containing germs on the surface of the xylitol-containing germs contained in the vessel, in removing the xylitol-based granules and the other polyol from the vessel and in crystallising the xylitol and other polyol contained in said granules, wherein the xylitol-based granules and the other polyol in thevessel are movable by the vessel rotation.

Description

technical field

[0001] The present invention relates to a process for the continuous preparation of a powder comprising crystalline particles of xylitol and other polyols present in lower proportions. Background technique

[0002] The term "other polyols" in the sense of the present invention refers to polyols, preferably selected from the group consisting of threitol, erythritol, arabitol, ribitol, sorbitol, mannitol, maltitol, maltotriitol, maltotetraose Alcohol, Lactitol, Hydrogenated Isomaltulose, Glycerin and Hydrogenated Starch Hydrolysates, alone or in combination.

[0003] More preferably, the other polyhydric alcohols are selected from sorbitol, maltitol, mannitol and hydrogenated isomaltulose, used alone or in combination.

[0004] The term "lower proportion" in the sense of the present invention means that the content of said other polyols in the powder comprising xylitol crystalline particles is 2.5 to 15% by weight, preferably 5 to 10% by weight, of the total a...
