What it is

Citric acid is a weak organic acid found naturally in citrus fruits like lemons and limes. It is commercially produced by fermenting sugars with specific strains of the mold Aspergillus niger. The blend typically combines citric acid with other ingredients, often to improve handling or stability.

Why it's used

Citric acid is used as an acidity regulator, preservative, and flavor enhancer in many foods and beverages. It provides a tart, sour taste and helps prevent spoilage. It's commonly found in candies, jams, jellies, dairy products, and canned goods.

Health notes

International bodies like JECFA have evaluated citric acid, and EFSA has also assessed its safety. No significant health concerns are associated with typical dietary intake.
