Description
Citric acid is a weak organic acid. It serves not only as a natural preservative but is also frequently employed to impart an acidic or sour taste to foods and soft drinks. In the field of biochemistry, citrate, the conjugate base of citric acid, is of great significance as a key intermediate in the citric acid cycle. As such, it plays a crucial role in the metabolic processes of nearly all living organisms.
Citric acid appears as a colorless or white crystalline powder. In the food and beverage sectors, it is mainly utilized as an acidulant, flavoring agent, and preservative. Additionally, it can function as an antioxidant, plasticizer, and detergent builder.
Applications
Food and Beverage Industry: Citric Acid primarily acts as an acidulant, flavor enhancer, preservative, and freshness-keeper. In the food industry, Citric Acid Monohydrate is commonly used as the acidulant for beverages. It is widely applied in the production of various cold drinks, as well as foods such as soda, candies, biscuits, cans, jams, fruit juices, etc. Moreover, it can be used as an antioxidant for oils and fats.
Pharmaceutical Industry: Citric Acid Monohydrate is the raw material for numerous pharmaceuticals. Examples include Piperazine Citrate (an anthelmintic), Ferric Ammonium Citrate (a hematinic), and Sodium Citrate (a transfusion pharmaceutical). Furthermore, citric acid is also used as an acidifier in many medications.
Chemical Industry: The esters of citric acid can be used as acidity regulators in the production of plastic films for food packaging.
