How does xylitol differ from other sweeterners?
Chemically speaking, xylitol is not actually a sugar, but a sugar alcohol. It differs from other sweeteners such as sorbitol, fructose and glucose because the xylitol molecule has five, instead of six, carbon atoms. Most bacterias in mouth are unable to make use of such sugars. This is one reason why xylitol helps prevent caries. Xylitol is much sweeter than sorbitol, for instance. Assessed in terms of calories, its sweetening power is the same as that of sucrose. It is also similar to sucrose in its technical and nutritive properties. Xylitol is an important supplement in the preventation of dental caries, and everyone interested in healthy teeth should be familiar with its properties and effects.
