What it is

Citric acid is a weak organic acid found naturally in citrus fruits like lemons and oranges. It is produced commercially through the fermentation of sugar by specific molds, primarily Aspergillus niger. This process yields a white crystalline powder that is highly soluble in water.

Why it's used

Manufacturers add citric acid to foods and beverages to control acidity, enhance flavor, and act as a preservative. It provides a tart, sour taste and can help prevent spoilage by inhibiting microbial growth. It is commonly found in candies, jams, jellies, soft drinks, and processed fruits and vegetables.

Health notes

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 production cycle (Krebs cycle). International bodies like JECFA have evaluated citric acid and established acceptable daily intake levels. At typical consumption levels, it is not associated with adverse health effects. Evidence does not suggest a link between citric acid consumption and negative health outcomes.

Allergen info

Citric acid is not derived from any of the nine FDA major allergens. It does not contain gluten.
