Abstract
Xylitol which is useful as a sugar substitute is produced from xylan containing natural products by: acid hydrolyzing xylan to xylose; concentrating the hydrolysis solution to remove acetic acid by-product; diluting with water; adjusting the pH to about 6.5 to about 7.5; catalytically hydrogenating the xylose to xylitol under pressure; and recovering xylitol by extraction.
