Citric acid CAS NO.:77-92-9

In the food industry, citric acid is often used as a flavoring agent to
increase the acidity of foods and improve their taste. For example, the
addition of citric acid to the preparation of foods such as candies, cookies,
breads, jams, beverages, and canned foods can make the food taste better and
promote appetite. In addition, citric acid is used as a preservative that
inhibits bacterial growth and improves the color stability of foods, thereby
extending their shelf life.
Citric acid also plays an important role in the cosmetics industry. It acts
as a mild cleanser, helping to remove dirt and oil from the surface of the
skin, leaving it refined and smooth. In addition, citric acid softens the
stratum corneum to some extent and improves skin roughness.
In addition to the food and cosmetic industries, citric acid has a wide range
of applications in other fields. For example, in cellulose production, citric
acid can be used to make biodegradable materials, which has important
environmental applications. In addition, citric acid is used in the
production of liquid fertilizers, as it forms a protective layer on plant
roots, preventing the invasion of pathogens and promoting plant growth and
development.
