Xylitol and Sugar


Xylitol is a widely used sugar alcohol in the food industry, known for its sweet taste, low caloric value, and low absorption rate. However, during production, xylitol may be contaminated with trace impurities that must be removed to meet food-grade standards. Activated carbon, with its excellent adsorption capacity, is an ideal solution for purifying xylitol and other sugars, effectively improving product purity and quality.

The adsorption process involves both physical and chemical mechanisms. Activated carbon’s well-developed microporous and mesoporous structure allows it to physically trap xylitol and sugar molecules on its surface through van der Waals forces and electrostatic attraction. This forms a stable adsorption layer that efficiently captures impurities.

In addition, chemical adsorption also plays a role. Functional groups on the surface of activated carbon can chemically interact with certain impurities, further enhancing the purification effect. This dual adsorption mechanism ensures high-performance removal of color bodies, residual organics, and by-products commonly present in sugar alcohols.

Whether for xylitol, glucose, or other food-grade sugars, activated carbon offers a cost-effective and efficient purification solution. It helps manufacturers meet strict quality and safety standards while maintaining product performance—making it an indispensable material in sugar refining and food ingredient production.
