Carbonation is the process by which carbon dioxide gas is dissolved into a liquid, and it is a key component of soda. In the soda-making process, bubbles of carbon dioxide are driven into the liquid through a chemical reaction. To begin with, food-grade carbon dioxide is pressurized in special cylinders inside the machine. Then, this pressurized gas flows through tubes and diffuses rapidly when it comes into contact with water. This creates hundreds of tiny bubbles, which produce the characteristic fizzy effervescence that we associate with soda. Furthermore, these infused bubbles create pockets of air within the liquid to further enhance the texture and mouthfeel of sodas. Ultimately, this makes carbonation an essential element in any homemade soda maker and a perfect way to get your daily dose of refreshment!
