Is Citric Acid Real Food?

Approved

Citric acid is a naturally occurring organic acid found in high concentrations in citrus fruits like lemons and limes. Commercially, it's largely produced through the fermentation of carbohydrates, such as sugar, by certain strains of mold.

Why it’s in your food

The manufacturer’s reason.

Manufacturers use citric acid as a natural flavoring to add a sour taste, as a preservative due to its antimicrobial properties, and to adjust the pH level of foods and beverages.

FAQ

Frequently asked questions.

Where is citric acid found naturally?▾
Citric acid is abundant in many fruits and vegetables, particularly citrus fruits like lemons, limes, oranges, and grapefruit. It's also present in berries, tomatoes, and some dairy products, contributing to their tart flavor profile.
How is citric acid made for commercial use if not directly from fruit?▾
For commercial production, citric acid is primarily made through microbial fermentation. A common method involves feeding a specific strain of the mold Aspergillus niger with a carbohydrate source, such as corn syrup, which then produces citric acid as a metabolic byproduct. This acid is then isolated and purified.
What are the main functions of citric acid in food products?▾
In food, citric acid serves multiple purposes: it provides a tart, sour flavor, acts as a natural preservative by lowering pH and inhibiting microbial growth, and can also prevent discoloration in fresh-cut produce. It helps maintain the freshness and appeal of many items.
