Acid: E330

Citric acid is a weak organic acid found naturally in citrus fruits like lemons and oranges. It is commercially produced by fermenting a sugar source, typically from corn, with a specific strain of mold (Aspergillus niger). The resulting acid is then purified and crystallized.

Manufacturers add citric acid primarily to regulate acidity and enhance flavor in a wide range of foods and beverages. It acts as a preservative by inhibiting microbial growth and can also be used as an antioxidant to prevent spoilage. It is commonly found in jams, jellies, candies, soft drinks, and canned fruits and vegetables.

In the US, citric acid is generally recognized as safe (GRAS) by the FDA. It is a common component of the human diet and is metabolized through normal body processes. International bodies like JECFA and EFSA have evaluated citric acid and its salts, establishing acceptable daily intake levels. At typical consumption levels, it is not associated with adverse health effects.
