Function
Citric acid is mainly used as a sour agent, a solubilizer, a buffering agent, an antioxidant, a mite deodorant, a flavor enhancer, a gelling agent, a toner, and the like. In addition, citric acid has the effects of inhibiting bacteria, protecting color, improving flavor, and promoting sucrose conversion. Citric acid also has a chelating effect that can remove certain harmful metals. Citric acid can prevent oxidation caused by enzyme catalysis and metal catalysis, thus preventing discoloration and smelling of frozen fruits
Application
Citric acid is a weak organic acid. It is a natural preservative and is also used to add an acidic, or sour, taste to foods and soft drinks. In biochemistry, it is important as an intermediate in the citric acid cycle and therefore occurs in the metabolism of almost all living things. It also serves as an environmentally benign cleaning agent and acts as an antioxidant.
Citric acid exists in a variety of fruits and vegetables, most notably citrus fruits. At room temperature,citric acid is a white crystalline powder. It can exist either in an anhydrous (water-free) form or as a monohydrate the monohydrate forms when citric acid is crystallized from cold water.
