Acidulants, also known as acidity regulators, are food additives that adjust the acidity of food. Specifically:
Main functions: Acidulants play a crucial role in the flavor of beverages. Besides providing acidity, they also act as preservatives, mask metallic tastes, and enhance the flavor of other flavoring substances.
Auxiliary functions: Acidulants also help dissolve cellulose and substances such as calcium and phosphorus, promoting digestion and absorption.
Common types: Commonly used acidulants include citric acid, tartaric acid, and malic acid. Adding these acidulants can mimic the flavor of fruit. Lactic acid, acetic acid, and amino acids are sometimes added to beverages for blending. Phosphoric acid, an inorganic acid, is mostly used in non-fruit-based soft drinks, such as cola.
