Citric acid monohydrate is used as a sour agent in food, and also used in the preparation of pharmaceutical cooling agents, detergent additives, etc.

Citric acid monohydrate is widely used in the food industry and can also be used as feed additives, non-toxic detergents, mordants, etc. At the same time, citric acid monohydrate can also be used in pharmaceuticals, chemicals, light industry, atomic energy, environmental protection and other industrial fields, and it is also an indispensable raw material for cosmetics, metal cleaning agents, resins, cardboard, tobacco, electroplating and so on. The discovery of citric acid monohydrate has a history of more than 200 years. As early as 1784, citric acid crystals were separated from lemon juice for the first time. In 1917, citric acid monohydrate was produced by the fermentation method of Aspergillus niger, and industrial production began.

Citric acid monohydrate is in the fields of food industry, medicine, cosmetics and oral chemical industry due to its non-toxicity, good solubility, delicious sour taste and excellent derivatization.

Citric acid monohydrate is safe and non-toxic, and it is called the first edible sour agent. It is widely used in beverage and fruit processing, soy products and flavoring agents. Citric acid is widely used, jelly, candy, wine, citric acid added to frozen food, can strengthen the antioxidant effect to inactivate enzymes, and ensure the stability of frozen food. Adding citric acid to vegetables and seafood can inhibit the growth of microorganisms and prolong the preservation time. Sodium citrate and potassium citrate are added as sour agents, food additives, etc. to jellies, cakes, and various beverages to improve flavor. According to statistics, about 7o% of the total production of citric acid is used in the food and beverage industry.

Citric acid monohydrate is also widely used in various nutritional oral liquids to adjust the pH of oral liquids, maintain the stability of ingredients, and ensure nutritional effects. Add citric acid to the shampoo, anti-dandruff shampoo and hair dye to adjust the pH, which can increase the gloss of the hair and restore the elasticity of the hair. Adding citric acid to cosmetics and toothpaste can prevent the product from decomposing and deteriorating.

Citric acid monohydrate is also widely used in the chemical industry. Citric acid itself is a chemical synthesis intermediate and the basic raw material for chemical synthesis. Because of its excellent performance, it is widely used as a cleaning agent, stabilizer, chelating agent and defoaming agent in the chemical industry. In recent years, with the enhancement of people’s awareness of environmental protection, sodium citrate has been more and more widely used in the production of green and environmentally friendly phosphate-free detergents.
