Citric acid anhydrous, with the chemical formula C₆H₈O₇, is an organic acid naturally found in citrus fruits. In its anhydrous form, it has a crystalline structure and does not contain water. Industrially, it is produced through the fermentation of sugar by microorganisms.

Used in food, cosmetics, and cleaning industries, citric acid anhydrous is a versatile compound. Its mild acidity allows it to function as a preservative and pH regulator. It is especially preferred for extending shelf life and enhancing flavor in food products. Commonly known as “lemon salt”, citric acid is widely used in both household and industrial cleaning. It acts as a natural descaler and is frequently used for kitchen and home cleaning purposes. In the food industry, it serves as a sweetener and preservative in carbonated drinks, fruit juices, and jams. Additionally, it is used to balance acidity in homemade pickles and preserves.

Chemical and Physical Properties of Citric Acid

Citric acid, with the chemical formula C₆H₈O₇, consists of carbon, hydrogen, and oxygen atoms. Its molecular structure contains three carboxyl (-COOH) groups and one hydroxyl (-OH) group, which contribute to its acidic properties and high water solubility.

The anhydrous form does not contain water, making it suitable for industrial applications and dry formulations. Its chemical stability ensures effective usage in various chemical reactions.

Chemical Properties of Citric Acid Anhydrous

  • As a mild acid, it fully dissolves in water, giving the solution an acidic property.
  • Used as a pH regulator in the food and chemical industries.
  • Decomposes at high temperatures, releasing carbon dioxide and water, enhancing the effectiveness of baking powders.
  • Forms complex compounds with metal ions, making it an essential ingredient in cleaning products.

Physical Appearance and Solubility

  • White, crystalline powder.
  • Highly soluble in water, alcohol, and acetone.
  • Hygroscopic, meaning it absorbs moisture from the air.
  • Must be stored in dry and cool environments to preserve its stability.
