Citric Acid: A Versatile Organic Acid for Food, Pharmaceutical, and Industrial Applications

Citric acid is one of the most widely used organic acids in the global market, valued for its versatility, safety, and effectiveness across multiple industries. Naturally occurring in citrus fruits such as lemons and oranges, citric acid is commercially produced through fermentation processes to meet large-scale industrial demand. Today, it plays a critical role in the food and beverage, pharmaceutical, cosmetic, detergent, and industrial sectors.

Thanks to its excellent chelating, buffering, preservative, and flavor-enhancing properties, citric acid remains a preferred ingredient for manufacturers worldwide.

What Is Citric Acid?

Citric acid (chemical formula C₆H₈O₇) is a weak organic acid that appears as a white, crystalline powder with a clean, sour taste. It is highly soluble in water and has strong metal-binding (chelating) properties, making it effective in both consumable and technical applications.

Commercial citric acid is typically derived from fermentation of carbohydrates such as corn or sugar using food-grade microorganisms. This process ensures consistent purity and compliance with international quality standards.
