Shaking a carbonated beverage reduces the stability of carbonic acid, accelerates the decomposition of carbonic acid, and produces carbon dioxide quickly, so shaken carbonated beverages produce foam quickly. Carbonated beverages category products are beverages filled with carbon dioxide gas under certain conditions. After shaking, the carbonic acid contained in carbonated beverages is unstable and easily decomposes into water and carbon dioxide. The decomposed carbon dioxide will overflow to form foam, while the carbonic acid is relatively stable if it is not shaken, and only less carbon dioxide overflows, so there is less foam. Carbonated beverages, the main ingredients include: carbonated water, citric acid and other acidic substances, sugar, flavors, some contain caffeine, artificial coloring and so on. In addition to sugar to replenish the body's energy, aerated "carbonated drinks" contain almost no nutrients. Excessive consumption is harmful to the body.
