Citric acid is used as a flavor enhancer in beverages. It is used in soft drinks, teas, juices, and other beverages to create a slightly tart, refreshing flavor and balance sweetness.
The acidic pH of citric acid also makes it useful as a preservative. Since many bacteria are unable to grow in an acidic environment, citric acid is often added to jams, jellies, candy, canned foods, and even meat products as a preservative.
Because citric acid can be made in a powder form, it can be used in dry foods when a sour flavor is desired. Citric acid is sometimes used to create an acidic environment and facilitate the ripening process when making cheese, particularly mozzarella.
A weak tribasic acid, citric acid is organic in composition. A vital part of metabolism in most living organisms, citric acid is widely prevalent in nature.
Citric acid is mass produced owing to its popular demand and vast applications. Some of the conventional uses of this acid are acidifiers, chelating agents and flavouring agents.
Citric acid prevails in two major forms, the anhydrous or water-free form and the monohydrate form. The anhydrous form is crystallized by application of hot water, whereas the monohydrate form is extracted by using cold water crystallization. Citric acid has numerous applications in the food industry and cosmetic industry.
