Citric Acid and the Peanut Free Diet

Citric acid is an organic acid that occurs naturally in citrus fruits such as lemons and limes. It is widely used in the food industry as a preservative and flavor enhancer due to its sour taste and ability to stabilize ingredients. Industrially, citric acid is often produced by fermenting a sugar solution with mold, typically Aspergillus niger, which may be grown on a corn-derived substrate.
