Taste thresholds: quality specific variation with human aging. 1982

J M Weiffenbach, and B J Baum, and R Burghauser

Detection thresholds for each of the four basic taste qualities were obtained from 81 adults between 23 and 88 years of age. Sodium chloride thresholds show a small but significant increase with age, confirming the only previous observations derived from procedures that control for age-related changes in response criterion and salivary sodium. Quinine sulfate thresholds display a similar but weaker relation to age. Sucrose and citric acid thresholds are not significantly related to age. Citric acid alone shows a sex effect. Detection thresholds for the four taste qualities undergo different changes with age.

D011803	Quinine	An alkaloid derived from the bark of the cinchona tree. It is used as an antimalarial drug, and is the active ingredient in extracts of the cinchona that have been used for that purpose since before 1633. Quinine is also a mild antipyretic and analgesic and has been used in common cold preparations for that purpose. It was used commonly and as a bitter and flavoring agent, and is still useful for the treatment of babesiosis. Quinine is also useful in some muscular disorders, especially nocturnal leg cramps and myotonia congenita, because of its direct effects on muscle membrane and sodium channels. The mechanisms of its antimalarial effects are not well understood.
