What is Citric Acid?

Citric acid is a weak organic acid that naturally occurs in citrus fruits such as lemons, limes, and oranges. In industrial settings, it is often produced through fermentation using Aspergillus niger mold, a process that efficiently yields large quantities suitable for food production.

Citric acid is widely used as an additive to impart a tart, tangy flavor to beverages and foods. It also serves as a preservative, helping to maintain freshness and inhibit the growth of bacteria. The health evidence suggests that citric acid is safe for consumption in the quantities typically used in food and drink products.

On labels, citric acid may be listed for its role either in flavor enhancement or as a preservation aid. It is generally considered non-toxic and unlikely to cause adverse effects when consumed in typical dietary amounts.

Commonly found in: soft drinks, candies, sauces, dressings, energy drinks
