Citric Acid

Citric acid is a naturally occurring organic acid found in citrus fruits, but commercially it's produced through fermentation. It appears as a white, odorless, crystalline powder and is widely used as a flavoring agent, preservative, and pH adjuster in food and beverages. Citric acid provides a distinctly tart, sour, and acidic flavor profile. It readily dissolves in water, imparting its characteristic tang to various culinary applications. Home cooks and industrial food manufacturers use it equally often due to its effectiveness and versatility.
