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, by the mold Aspergillus niger.

Why it's used

Manufacturers add citric acid to foods and beverages primarily to enhance flavor, acting as a souring agent and preservative. It is also used to control acidity and as an emulsifier, helping to blend ingredients like oil and water. You'll find it in candies, jams, sodas, and processed cheeses.

At typical consumption levels found in food, it is not associated with adverse health effects. There are no widespread controversies regarding its safety.
