Citric Acid – Uses, Grades, Benefits & Industrial Applications
What Is Citric Acid?
Citric acid is a naturally occurring weak organic acid found in citrus fruits such as lemons, limes, and oranges. Chemically known as C₆H₈O₇, citric acid is widely used across food processing, pharmaceuticals, cleaning products, cosmetics, and industrial manufacturing due to its excellent acidity regulation, chelating ability, and preservative properties.
It appears as a white crystalline powder, is odorless, and dissolves easily in water, making it highly versatile for both consumer and industrial applications.
