What it is

Citric acid (E330) is a weak organic acid found naturally in citrus fruits like lemons and limes. It is commercially produced through the fermentation of a sugar source, typically from corn or sugarcane, using specific strains of the mold Aspergillus niger.

Why it's used

Manufacturers add citric acid primarily as an acidity regulator, flavor enhancer, and preservative. It provides a tart, sour taste and helps prevent spoilage by inhibiting microbial growth. It is commonly found in beverages, candies, jams, jellies, and canned fruits and vegetables.

Health notes

In the United States, citric acid is generally recognized as safe (GRAS) by the FDA for use in food. International bodies like JECFA and EFSA have evaluated citric acid and established acceptable daily intake levels. At typical consumption levels found in food, it is not associated with adverse health effects. Some individuals may experience tooth enamel erosion with frequent consumption of highly acidic foods and drinks.

Allergen info

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