What it is

Citric acid is a weak organic acid found naturally in citrus fruits like lemons and oranges. It is commonly produced commercially through the fermentation of a sugar source, such as corn or beet sugar, using specific strains of the mold Aspergillus niger. This process yields a pure, crystalline powder.

Why it's used

Manufacturers add citric acid primarily as an acidity regulator, flavoring agent, and antioxidant. It provides a tart, sour taste and can help preserve foods by preventing spoilage and maintaining color. It is frequently found in beverages, candies, jams, jellies, and canned fruits and vegetables.

Health notes

Citric acid is generally recognized as safe (GRAS) by the 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, and they are considered safe for consumption. No significant health concerns are associated with typical dietary intake.

Allergen info

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