Abstract:
A process for obtaining crystalline xylitol substantially free of xylose from a mixture of xylose and xylitol by providing an aqueous solution of about 50 to 75 weight percent xylitol, no more than about 5 weight percent xylose and about 20 to 45 weight percent water and fractionally crystallizing xylitol from the aqueous solution to provide crystalline xylitol containing no more than about 0. 10 weight percent xylose.
