Citri Acid

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, such as corn or sugarcane, using specific strains of the mold *Aspergillus niger*. The resulting acid is then purified and crystallized.

Manufacturers add citric acid primarily to provide a tart, sour taste and to act as an acidity regulator, helping to control pH levels in foods. It also functions as a preservative by inhibiting microbial growth and as an antioxidant to prevent spoilage. It is commonly found in beverages, candies, jams, jellies, and canned fruits and vegetables.

Citric acid is Generally Recognized As Safe (GRAS) by the FDA for use in food. It is a natural component of the body's energy-producing metabolic pathways. International bodies like JECFA and EFSA have evaluated citric acid and its salts, finding them safe for consumption. At typical dietary levels, it is not associated with adverse health effects.
