Carbonated beverage essence is specially used for aerated beverage systems, such as flavored water, cola drinks, fruit flavored soda, etc. Its core characteristics lie in excellent acid resistance, explosive aroma, and synergistic performance with carbon dioxide stimulation. In the carbonic acid environment, essence not only needs to resist the degradation of flavor substances at low pH value, but also needs to release strong and clear aroma at the moment of opening the bottle to compensate for the natural attenuation of "vapor" over time.
