Carbonation

Carbonation is the process of dissolving carbon dioxide gas (CO2) into a liquid, like water or soda. This gas is naturally present in the atmosphere and is also produced during fermentation. In food production, CO2 is typically bubbled into beverages under pressure to create a fizzy sensation.

Manufacturers add carbonation to beverages to create a desirable fizzy texture and a tingling sensation on the tongue. It can also enhance flavors and add a slight tartness. Carbonation is commonly found in sparkling water, sodas, beers, and other alcoholic and non-alcoholic drinks.

Carbon dioxide used for carbonation is generally recognized as safe (GRAS) by the FDA for its intended use. Consuming carbonated beverages can sometimes lead to bloating or gas due to the release of CO2 in the digestive system. International bodies like JECFA have evaluated carbon dioxide and established acceptable intake levels. There are no widespread controversies regarding its safety at typical consumption levels.
