A Natural Acid Regulator

Citric acid is a weak organic acid found naturally in citrus fruits like lemons and limes. It is commonly produced industrially by fermenting a sugar source, such as corn or cane sugar, with a specific strain of mold (Aspergillus niger). This process yields a highly purified crystalline powder.

Citric acid is primarily used as an acidity regulator, flavor enhancer, and preservative in food products. It provides a tart, sour taste and helps control pH levels, which can inhibit microbial growth and maintain product stability. It is frequently found in beverages, candies, jams, jellies, and canned 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 the human diet and is involved in cellular energy production (the Krebs cycle). International bodies like JECFA (Joint FAO/WHO Expert Committee on Food Additives) have evaluated citric acid and found it to have no safety concerns at typical consumption levels. There are no widespread controversies regarding its safety as a food ingredient.
