What it is

Citric acid is a weak organic acid naturally found in citrus fruits like lemons and oranges. It is commercially produced through the fermentation of a sugar source (like corn or sugarcane) by a specific mold, Aspergillus niger.

Why it's used

Manufacturers add citric acid to foods and beverages primarily to provide a tart, sour taste and to act as an acidity regulator. It helps preserve food by inhibiting microbial growth and can also function as an antioxidant.

Health notes

Citric acid is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use in food. It is a common component of human metabolism. International bodies like JECFA and EFSA have evaluated citric acid and its salts, determining them to be safe for consumption. Evidence does not suggest adverse health effects from typical dietary intake.

Allergen info

Citric acid is not derived from any of the nine FDA major allergens. It does not contain gluten.
