Why is carbon dioxide added to beverages?

You may already know that some beverages contain a certain amount of carbon dioxide, which is why they make a hissing sound when you shake the bottle. But why is carbon dioxide used in cold drinks?

The primary reason for using carbon dioxide as a beverage additive is based on its solubility, which is one of the most important factors when any gas mixes with liquid. Carbon dioxide is the most easily soluble common non-toxic gas. When gaseous carbon dioxide comes into contact with water, a chemical reaction occurs to produce carbonic acid, which gives you a sour and sweet sensation. The decomposition of carbonic acid releases carbon dioxide, which is the main reason for the "fizz" in cold drinks and other beverages. This foam not only looks cool and tastes good, but also has a strangely pleasing sound.

When people drink carbonated beverages, the high temperature causes some of the carbon dioxide to vaporize, producing stimulation that takes away heat from the mouth and gives a refreshing feeling. After drinking it into the stomach, body temperature causes the remaining carbon dioxide to vaporize again, taking away heat from the stomach and making people feel even more refreshed and quenched. Therefore, it's no wonder that carbonated drinks have remained popular over time.
