Propyl Gallate And Citric Acid As Antioxidants

Propyl gallate is a synthetic antioxidant. It is made from gallic acid, which can be found in plants like tea leaves and oak bark. Citric acid is a common food acid found naturally in citrus fruits.

Propyl gallate and citric acid are often used together as antioxidants in packaged foods. They help prevent fats and oils from spoiling, which can cause off-flavors and odors. They are commonly found in products containing fats, such as shortenings, oils, and baked goods.

Propyl gallate is generally recognized as safe (GRAS) by the FDA for use as an antioxidant. Both FDA and EFSA have evaluated its safety. Some studies have raised questions about potential allergic reactions or other health effects, but regulatory bodies consider it safe at typical consumption levels. Evidence is mixed on whether it causes hyperactivity in children.
