Xylitol 337<br />

Milled forms of xylitol range in mean particle sizes from approximately 50 to<br />

200 microns. The granulated forms of xylitol are suitable for direct compression.<br />

III. PROPERTIES AND APPLICATIONS<br />

At present, xylitol is used as a sweetener mainly in noncariogenic confectionery<br />

(chewing gum, candies, chocolates, gumdrops), and less frequently in dietetic<br />

foods (food products for people with diabetes), in pharmaceutical preparations<br />

(tablets, throat lozenges, multivitamin tablets, cough syrup), and in cosmetics<br />

(toothpaste and mouthwash) (33–39). Xylitol is used at low levels in selected<br />

low-calorie soft drink applications to improve product mouthfeel and sweetness<br />

profile. In principle, the manufacture of various baked goods with xylitol is possible.<br />

However, if crust formation, caramelization, or nonenzymatic browning is<br />

required, the addition of a reducing sugar is necessary. Because xylitol inhibits<br />

the growth and fermentative activity of yeast, it is not a suitable sweetener for<br />

products containing yeast as a leavening agent (40,41).<br />

A. Sweetness<br />

Xylitol is the sweetest polyol (Fig. 1) (42–46). At 10% solids (w/w) xylitol is<br />

isosweet to sucrose, whereas at 20% solids (w/w) xylitol is about 20% sweeter<br />
