isomalt is combined with other sugar alcohols (e.g., xylitol, sorbitol, mannitol,<br />

maltitol syrup, hydrogenated starch syrup) and with high-intensity sweeteners<br />

(e.g., acesulfame K, aspartame, sucralose, cyclamate, or saccharin). In addition,<br />

isomalt tends to mask the bitter metallic aftertaste of some intense sweeteners (4).<br />

B. Cooling Effect<br />

Several sugar alcohols, used as sugar substitutes, have a high negative heat of<br />

solution (6–8). This results in a cooling sensation in the mouth when these sugar<br />

alcohols are consumed in a crystalline or solid state. Although this mouth-cooling<br />

effect is a desirable feature for peppermint or menthol products, it is considered<br />

atypical in many other products, such as baked products and chocolate. The negative<br />

heat of solution of isomalt-ST lies between the values of GPS and GPM.<br />

Figure 3 shows that, compared with other sugar alcohols, isomalt has a very low<br />

negative heat of solution, which is comparable to that of sucrose. Isomalt, therefore,<br />

does not produce a cooling effect.<br />
