Citric acid
An organic acid that gives citrus fruit its tartness, used to adjust pH and flavor.
i Additive Details
| Uses
Adds tartness and adjusts the pH of soft drinks, candies, jams and jellies, canned tomatoes, ice cream, ready-to-eat sauces, and an enormous range of processed foods. Also used as a pH regulator in cosmetics.
| Precautions
Generally regarded as safe. A small number of case reports describe inflammatory reactions in sensitive individuals, possibly linked to residues from mold-based fermentation. Frequent exposure to acidic candies and drinks can contribute to dental erosion.
| Interactions
A natural intermediate in the citric acid cycle (Krebs cycle), the central pathway of cellular energy production. Chelates metal ions, which extends shelf life by tying up iron and copper that catalyze oxidation.
| Origin
Almost all commercial citric acid is produced by fermentation of glucose or sucrose with the mold Aspergillus niger. It also occurs naturally in lemons, limes, oranges, and many fruits.
| Daily Intake
JECFA and EFSA both list citric acid with 'ADI not specified', the safest category, meaning intake at the levels needed for its technical function is not a concern.
