Citric acid is a versatile organic compound widely used in various industries, known for its sour and tangy taste. This naturally occurring acid is found in citrus fruits like lemons and oranges but is typically produced on a larger scale through fermentation processes. In the realm of chemistry, it serves as a crucial acidulant, pH regulator, and chelating agent. Its applications range from being a flavor enhancer in food and beverages to a cleaning agent in household products, as well as a key ingredient in cosmetics and pharmaceuticals. Citric acid's ability to efficiently remove mineral deposits and its mildness on the skin make it a valuable component in many everyday items, contributing to its significant presence in our daily lives.
