Citric Acid CAS#77-92-9

Citric Acid CAS#77-92-9

High Solubility & Versatility:It is highly soluble in water and ethanol, making it ideal for use as an acidulant, preservative, and stabilizer in food, pharmaceuticals, and cosmetics.


Industrial Applications:Widely used in food processing, pharmaceuticals, and cleaning products, citric acid serves as a preservative, pH regulator, and flavor enhancer.


Hygroscopic & Stable: Citric acid absorbs moisture from the air but remains stable when stored at 2-8°C, with a high melting point (153-159°C) and boiling point (248°C).


Acidic & Safe: With a low pH, it is effective in various applications. However, it may irritate skin and eyes, requiring safe handling.

ABOUT THE PRODUCT

Product Description

Product Description-Citric Acid CAS#77-92-9


Anhydrous citric acid is a naturally occurring metabolic intermediate in both plants and animals, and one of the most widely used organic acids in the food, pharmaceutical and chemical industries. It appears as colorless transparent or semi-transparent crystals, granules or fine powder.


It is odorless with a strong, pleasantly tart taste and a slight astringent afternote. It gradually effloresces in warm air and exhibits mild deliquescence in humid conditions.

Product Applications-Citric Acid CAS#77-92-9


Citric acid is a weak organic acid that is known as a commodity chemical, as more than a million tonnes are produced every year by mycological fermentation on an industrial scale using crude sugar sol utions, such as molasses and strains of Aspergillus niger. Citric acid is widely distributed in plants and in animal tissues and fluids and exist in greater than grace amounts in variety of fruits and vegetables, most notably in citrus fruits such as lemon and limes. Citric acid is mainly used as an acidifier, flavoring agent and chelating agent. It was also used as a chemical restrainer particularly in developers for the collodion process and in silver nitrate solutions used for sensitizing salted and albumen papers.
