What it is

Citric acid is a weak organic acid found naturally in citrus fruits like lemons and oranges. It is produced commercially through the fermentation of carbohydrate feedstocks, typically using a strain of the mold Aspergillus niger. This process yields a highly pure, crystalline powder.

Why it's used

Citric acid is primarily used as an acidity regulator, flavoring agent, and preservative in food and beverages. It provides a tart, sour taste and can enhance the effectiveness of antioxidants. It is commonly found in soft drinks, candies, jams, jellies, and processed fruits and vegetables.

Health notes

Citric acid is Generally Recognized As Safe (GRAS) by the FDA for use in food. International bodies like JECFA and EFSA have also evaluated citric acid and found it safe for consumption. At typical dietary levels, it is not associated with adverse health effects. Some individuals may experience tooth enamel erosion with frequent consumption of highly acidic foods and drinks containing citric acid.

Allergen info

Citric acid is not derived from any of the nine FDA major allergens and does not contain gluten. It is considered a safe ingredient for individuals with allergies.
