TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The sweetening agent is selected from sucrose, trichlorosucrose, xylitol, phyllodulcin, liquiritin, stevioside, aspartame, acesulfame potassium, and/or sodium cyclamate. The sour agent is selected from citric acid, tartaric acid, and/or malic acid. The aromatic material is selected from Eucalyptus oil, orange oil, peppermint oil, dementholized peppermint oil, L-menthol, or vanillin.    TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The flavoring agent comprises sweetening agent, sour agent, aromatic material, high molecular weight gum material, lecithin, cephalin, and/or phosphatidic acid. The high molecular weight gum material comprises xanthan gum, guar gum, tragacanth, locust bean gum, and/or gum Arabic. The zolpidem tartrate film agent comprises (wt.%) zolpidem tartrate (1-40, preferably 5-30), high molecular weight film forming material (40-98, preferably 56-89), plasticizer (0-20, preferably 0-15), titanium dioxide (0-3), flavoring agent (1-30, preferably 6-20), and other auxiliary materials (0-1, preferably 0-0.1), where total weight is 100 wt.%. It comprises (wt.%) zolpidem tartrate (10-20), high molecular weight film forming material (46-56), plasticizer (10-15), titanium dioxide (1-2), and flavoring agent (18-20), where total weight is 100 wt.%.
