Citric Acid To Preserve Freshness

Citric acid is a weak organic acid found naturally in citrus fruits like lemons and oranges. It is commercially produced through the fermentation of a sugar source, typically from corn, using a specific strain of mold (Aspergillus niger). This process yields a pure, crystalline powder.

Manufacturers add citric acid primarily as an acidity regulator and preservative. It helps to enhance flavor, maintain freshness, and prevent spoilage in a wide variety of foods and beverages. It is commonly found in processed fruits, candies, soft drinks, jams, and dairy products.

In the U.S., 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 found it safe for consumption. There is no widespread scientific controversy regarding its safety at typical dietary levels.
