Currently, carbon dioxide (CO2) used in soda and beer production mainly comes from fermentation CO2 (C02) (produced during alcohol fermentation), chemical plant waste CO2 (CO2), and CO2 produced by acid-base reactions. For remote or industrially less developed areas, the acid-base reaction method is commonly used to produce CO2. The principle of CO2 production by acid-base neutralization involves a chemical reaction between citric acid (C6H8O7) and sodium bicarbonate (NaHCO3) to produce carbon dioxide gas (CO2), as shown in the reaction equation:
