Did you know that carbonation has a distinct taste? According to new research from the National Institute of Dental and Craniofacial Research scientists have elucidated the fine intricacies of fizziness. When consuming a carbonated beverage the sensation of tiny bubbles bursting on your tongue is, in fact, misleading. If one were to drink a soda in a pressure chamber (thus preventing the bubbles from bursting) the sensation would actually be the same. What gives? The “taste” of carbonation involves the interaction of an enzyme, carbonic anhydrase 4, with the sour-sensing cells in your taste buds. This interaction sends signals to the brain where carbonation is perceived as the familiar fizz, followed by a sensation of tartness. [via NIH News]
