Citric Acid And Propyl Gallate

Citric acid is a weak organic acid found naturally in citrus fruits like lemons and limes, and is commercially produced through the fermentation of carbohydrates. Propyl gallate is a synthetic antioxidant, an ester of gallic acid (found in plants) and propanol.

When used together, citric acid acts as an acidity regulator, flavor enhancer, and preservative, while propyl gallate functions as an antioxidant. This combination helps prevent fats and oils from becoming rancid, maintains food quality, and enhances flavor. They are often found in fatty snack foods like popcorn, peanuts, and some frozen meals.

Citric acid is considered Generally Recognized As Safe (GRAS) by the FDA, and JECFA and EFSA have determined that an acceptable daily intake does not need to be specified. Propyl gallate is permitted by the FDA as a synthetic antioxidant, and JECFA and EFSA have evaluated it and set an acceptable daily intake. Both ingredients are generally considered safe for consumption at typical levels found in food.
