Introduction to Carbonated Beverage Production

The process of carbonation is an essential and core element within the making of carbonated beverages. The key principle is the procedure of carbon dioxide ($CO_{2}$) gas being totally dissolved into a liquid at a set pressure—optionally water or flavored syrup—such that the effervescent viscosity indicative of drinks is achieved. Carbonating capacity is a function of temperature, pressure, and the solubility of $CO_{2}$ in a liquid. The association is with greater amounts of $CO_{2}$ being absorbed at lower temperatures and higher pressure. When this operation is complete, the product must be immediately canned or bottled into 100% full systems in order to preserve the gas and the fizzy texture of the preserved beverages.
