Citric Acid (C₆H₈O₇) is a high-purity, white, water-soluble organic acid widely used in food, beverage, pharmaceutical, cosmetic, and various industrial applications. It functions primarily as a pH regulator, preservative, and chelating agent, ensuring product stability, quality, and performance. While naturally found in citrus fruits like lemons and oranges, industrial Citric Acid is typically produced via fermentation for consistent purity and effectiveness.
