What it is

Citric acid 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 other plant starches, using a mold called Aspergillus niger. The resulting citric acid is then purified and crystallized.

Why it's used

Manufacturers add citric acid to foods and beverages primarily to enhance flavor by providing a tart or sour taste. It also acts as a preservative by inhibiting the growth of bacteria and mold, and as an antioxidant to prevent spoilage. It is commonly found in candies, jams, jellies, soft drinks, and processed fruits and vegetables.

Health notes

Citric acid is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use in food. International bodies like the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated citric acid and found it to be safe for consumption. At typical dietary levels, it is not associated with adverse health effects. There are no significant controversies regarding its safety.

Allergen info

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