Carbonated beverages

Carbonated beverages are a type of drink that contain dissolved carbon dioxide gas. The process of dissolving carbon dioxide gas is known as carbonation. This process can occur naturally, such as in naturally carbonated mineral water that has absorbed carbon dioxide at high pressures underground, or by man-made processes.

History

The first drinks to be carbonated were made in the 17th century. The technique was developed by chemists who were seeking to replicate naturally carbonated mineral waters that were believed to be healthy. The first commercially available carbonated beverages were marketed in the 18th century. The term "soda water" was first coined in 1798.

Production

Carbonated beverages are produced by dissolving carbon dioxide in water under pressure. When the pressure is removed, the carbon dioxide is released from the solution as small bubbles, which gives the drink its fizz. The amount of carbon dioxide pressure and the temperature of the water determine the amount of carbon dioxide that can be dissolved.

Types of Carbonated Beverages

There are many types of carbonated beverages, including soft drinks, soda water, sparkling water, seltzer water, and carbonated juice. Some carbonated beverages, such as colas and root beer, contain caffeine. Others, such as ginger ale and lemon-lime soda, do not.

Health Effects

There is ongoing debate about the health effects of carbonated beverages. Some studies suggest that they may contribute to obesity, tooth decay, and osteoporosis. However, other studies have found no association between carbonated beverage consumption and these health problems.
