What it is

Citric acid is a weak organic acid found naturally in citrus fruits like lemons and oranges. It is commercially produced through the fermentation of a sugar source, typically from corn, using a specific strain of the mold Aspergillus niger. The resulting citric acid is then purified and crystallized.

Why it's used

Manufacturers use citric acid primarily as an acidity regulator and preservative. It adds a tart, sour taste to foods and beverages, enhancing flavor profiles. It is commonly found in processed foods such as jams, jellies, candies, soft drinks, and canned fruits and vegetables.

Health notes

In the US, citric acid is generally recognized as safe (GRAS) by the FDA for use as a food additive. It is also approved as a food additive. International bodies like JECFA and EFSA have evaluated citric acid, and it is widely consumed without significant health concerns at typical dietary levels. There are no widespread controversies regarding its safety.

Allergen info

Citric acid is not derived from any of the nine major allergens recognized by the FDA, nor does it contain gluten. Not a major allergen.
