What it is
Citric acid is a weak organic acid found naturally in citrus fruits like lemons and limes. For commercial use, it is primarily produced through the fermentation of carbohydrates, often using the mold Aspergillus niger.
Why it's used
It is widely used in food and beverages as a natural preservative, an acidity regulator to provide a tart flavor, and an emulsifying agent. It helps prevent spoilage, enhances flavors, and can act as an antioxidant. It's found in soft drinks, candies, processed fruits and vegetables, and snack foods.
Health notes
The U.S. Food and Drug Administration (FDA) recognizes citric acid as Generally Recognized As Safe (GRAS). It is considered safe for consumption at levels typically found in food. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated citric acid and did not set a numeric acceptable daily intake (ADI not specified), concluding that it is safe. The European Food Safety Authority (EFSA) has also evaluated citric acid and considers it safe for use as a food additive. There are no notable controversies regarding its safety at typical intake levels.
