Cola
From Wikipedia, the free encyclopedia
Cola is a beverage usually with caramel coloring and containing caffeine.[1]
Originally invented by the druggist John Pemberton, it has become popular worldwide. Coca-Cola has become the major international brand, leading to the drink often being seen as a symbol of the United States. Modern colas very rarely contain any kola nut—the origin of the name—as the taste of this nut is strongly bitter.

[edit] Flavorings
Despite the name, the primary flavoring ingredients in a cola drink are sugar, citrus oils (orange, lime, or lemon fruit peel), cinnamon, vanilla, and an acidic flavorant[2]. Manufacturers of cola drinks add other trace ingredients to the drink in addition to these flavorings in order to create distinctively different tastes for each brand. Trace flavorings may include nutmeg, lavender, and a wide variety of ingredients, but the base flavorings that most people identify with a cola taste remain vanilla and cinnamon. Kola nuts, which have a bitter taste, although giving their name to the product, contribute little or no flavor to most cola recipes. Acidity is often provided by phosphoric acid, sometimes accompanied by citric or other isolated acids.
Inexpensive colas may contain only vanilla and cinnamon as flavorings, which provide a simple cola taste[citation needed]. Many cola drink recipes are closely-guarded secrets of their manufacturers[citation needed], with the recipe used by Coca-Cola being perhaps the most famous in this respect.
In addition to high fructose corn syrup, various sweeteners may be added to cola, including sugar, stevia, or an artificial sweetener depending on product and market. "Sugar-free" or "diet" colas contain artificial sweeteners only.

[edit] Chemical and medical reactions
Being carbonated, colas are acidic (carbonic acid is formed when carbon dioxide dissolves in water), and so can react violently with basic chemicals, such as baking soda. Many colas also contain phosphoric acid and/or citric acid, which further increases the acidity.[3] Colas containing phosphoric acid have been linked to chronic kidney disease.[4] Drinking two or more of these colas per day more than doubled the incidence of kidney disease, while colas containing citric acid did not have an effect.
Drinking more than 2l of cola a day may lead to hypokalaemia[5] (potassium deficiency), leading to muscle wastage and paralysis.
The Diet Coke and Mentos eruption is a popular experiment. Mentos candies and crystalline powders such as sugar and salt, when added to cola (usually diet coke), cause fizzing by providing many micronucleation points for the carbon dioxide to leave solution. This, however, is a physical reaction resulting from the release of dissolved CO2 as opposed to a chemical reaction.
Another experiment involves adding dry ice. By providing additional carbon dioxide, some of the carbon dioxide present in the drink is forced out of the solution, creating an explosion and destroying the bottle.
In either case, mixing these substances with cola (or any other carbonated drink) causes the drink to bubble, creating foam and greatly increasing the pressure in the bottle, resulting in either the bottle or the cap giving way.[3]
[edit] Etymology
The word cola may have been introduced into the mainstream by the major producer Coca-Cola, as they saw their trademark slipping into common use, like other genericized trademarks. They successfully defended the exclusive use of their name and its diminutive form "Coke" by suggesting the alternative of "cola drink" as a generic name for similar types of carbonated soft drinks. The word cola as part of the Coca-Cola trademark may have originated from the kola nuts that were originally used as the source of caffeine, or from when the original recipe contained coca (from which cocaine is derived).
