Tomato Juice Citric Acid

Citric acid is a weak organic acid found naturally in citrus fruits like lemons and limes. It is commonly produced commercially through the fermentation of a sugar source, such as corn or sugarcane, by a specific strain of mold (Aspergillus niger). The resulting acid is then purified and crystallized.

Citric acid is primarily used as an acidity regulator and preservative in food and beverages. It adds a tart, sour taste, enhances flavors, and helps prevent spoilage by inhibiting microbial growth. It is frequently found in processed foods, including canned fruits and vegetables, jams, candies, and soft drinks.

In the U.S., citric acid is generally recognized as safe (GRAS) by the FDA when used as a food additive. It is also approved as a food additive in Europe by EFSA. International bodies like JECFA have evaluated citric acid and found no safety concerns at typical consumption levels. Evidence does not suggest adverse health effects from consuming foods containing citric acid at normal levels.
