What it is

Citric acid is a weak organic acid found naturally in citrus fruits like lemons and oranges. It is commercially produced by the fermentation of carbohydrate feedstocks, such as corn starch, using specific strains of the mold Aspergillus niger. It is a common food additive used to enhance flavor and as a preservative.

Why it's used

Citric acid is primarily used as an acidity regulator, flavoring agent, and preservative in a wide variety of foods and beverages. It provides a tart, sour taste and helps to balance sweetness. It is frequently found in jams, jellies, fruit juices, candies, and processed foods.

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 dietary component and is metabolized by the body. International bodies like JECFA and EFSA have evaluated citric acid and its salts, and they have established acceptable daily intakes. No significant health concerns are associated with typical dietary consumption.

Allergen info

Citric acid is not derived from any of the nine FDA major allergens (milk, egg, fish, shellfish, tree nuts, peanuts, wheat, soy, sesame). It does not contain gluten.
