What it is

Citric acid is a weak organic acid found naturally in citrus fruits. It is commercially produced by the fermentation of carbohydrates using specific strains of the mold Aspergillus niger.

Why it's used

Citric acid is widely used as an acidity regulator, flavor enhancer, and preservative in foods and beverages. It provides a tart, sour taste and helps to prevent spoilage, making it common in soft drinks, candies, jams, and processed foods.

Health notes

Citric acid is generally recognized as safe (GRAS) by the FDA for use in food. It is a natural component of metabolism and is safely processed by the body. International bodies like JECFA have evaluated citric acid and found it safe for consumption. While generally considered safe, excessive intake of acidic foods and drinks can potentially contribute to dental erosion.

Allergen info

Citric acid is not derived from any of the 9 major allergens. It does not contain gluten.
