Assigment 7 : Cool baverages - soft drinks carbonation

             In many consumer beverages such as soft drinks, carbonation is used to give "bite." The fizzy taste can be caused by dilute carbonic acid inducing a slight burning sensation, but is never caused by the presence of bubbles. This can be shown by drinking a fizzy drink in a hyperbaric chamber at the same pressure as the beverage. This can give much the same taste as at sea level. In any case, the bubbles will be completely absent during this experience. If you were to taste a flat soda at this pressure, you might experience a much different flavor profile as carbonic acid has a low vapor pressure, and the only "bite" would come from other acids in the soda. However, in the case of Pepsi and Coca-Cola, much of the perceived bite is due to phosphoric acid, an acid not known for fizz or changes in flavor profile due to changes in pressure.

           Carbonation is sometimes used for reasons other than taste. For example, carbonation reduces the availability of free oxygen in a soda, and it can reduce the pH of a liquid by a small amount. Some carpet cleaning solutions are carbonated to more effectively dissolve organic                     

           Carbonation also has therapeutic applications in particular the delivery of vitamin supplements whereby the carbonation of the active ingredients allows for a faster and more efficient delivery of nutrients. This is achieved in two ways.

1. The solution is activated instantly and once taken orally is  

    absorbed through vessels in the mouth and tongue.

2. The remaining liquid is absorbed much quicker and efficiently in

    the gut.

           A soft drink (widely referred to as soda, pop, or soda pop) is a drink that contains a negligible amount of alcohol as compared to wines. Soft drinks are often carbonated and commonly consumed while cold. Some of the most common soft drinks include cola, flavored water, sparkling water, iced tea, sweet tea, sparkling lemonade (or other lemon-lime sodas), squash, fruit punch, root beer, orange soda, grape soda, cream soda, and ginger ale.

       The term "soft" is employed in opposition to "hard", i.e. alcoholic drinks. Generally it is also implied that the drink does not contain milk or other dairy products. Hot chocolate, hot tea, coffee, tap water, juice and milkshakes also do not fall into this classification. Many carbonated soft drinks are optionally available in versions sweetened with sugars or with non-caloric sweeteners.
