Citric Aicd

Citric acid is a weak organic acid that occurs naturally in citrus fruits like lemons and limes. It is commonly produced commercially through the fermentation of carbohydrates by microorganisms, such as the mold Aspergillus niger.

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, improve texture, and as an emulsifier, helping to blend oil and water. You'll find it in candies, jams, soft drinks, and processed fruits and vegetables.

In the U.S., citric acid is generally recognized as safe (GRAS) by the FDA. It is a common component of human metabolism and is safely consumed in typical food amounts. International bodies like JECFA and EFSA have evaluated citric acid and established acceptable daily intake levels. Evidence does not suggest adverse health effects from its consumption at normal dietary levels.
