Citric Acid Preservative

Citric acid is a weak organic acid found naturally in citrus fruits like lemons and limes. It is commercially produced by fermenting a sugar source, such as corn or sugarcane, using a specific strain of mold (Aspergillus niger). This process yields a pure, crystalline powder that is widely used in the food industry.

Manufacturers add citric acid primarily to control acidity and enhance flavor in foods and beverages. It acts as a preservative by preventing the growth of bacteria and mold, and also helps to stabilize food products. It is commonly found in candies, jams, jellies, soft drinks, and processed fruits and vegetables.

Citric acid is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use in food. It is a natural component of metabolism and is safely processed by the body. International bodies like JECFA and EFSA have evaluated citric acid and found it to be safe for consumption. While generally considered safe, very high intakes could potentially erode tooth enamel over time, though this is uncommon with typical dietary consumption.
