Carbon dioxide gas is formed from the combination of two elements: carbon and oxygen. It is produced from the combustion of coal or hydrocarbons, the fermentation of liquids and the breathing of humans and animals.
Food Industry
- CO2 is used in the food business in Carbonation of fizzing beverages such as soft drinks, mineral water or beer, Packaging of foodstuffs, its inerting and bacteriostatic properties being used successfully in nitrogen mixtures (Modified Atmosphere Packaging or MAP), to increase the shelf life of many food products. As cryogenic fluid in chilling or freezing operations or as dry ice for temperature control during the distribution of foodstuffs. Caffeine is removed from coffee using supercritical CO2.
