PROCESS FOR MANUFACTURING XYLITOL AND XYLITOL-RICH PRODUCTS

摘要

Process for manufacturing xylitol and xylitol-rich products, characterized in that it consists of: - enzymatically isomerizing at M1 D-xylulose syrup into syrup containing D-xylose and D-xylulose then, without extracting the xylose, - catalytically hydrogenating this syrup at M2, resulting thus in a xylitol-rich syrup, said xylitol-rich syrup being either dehydrated, or subjected to chromatographic processing or to a treatment of extraction by crystallization at M3.
