Propyl Gallate To Maintain Freshness

Propyl gallate is a synthetic antioxidant. It is made from gallic acid, which can be derived from plant sources like gallnuts, but is often produced synthetically. It is then esterified with propanol.

Propyl gallate is added to foods to prevent fats and oils from becoming rancid, thus maintaining freshness and extending shelf life. It is commonly found in products containing fats and oils, such as baked goods, cereals, snack foods, and processed meats.

In the US, propyl gallate is permitted as a food additive. Regulatory bodies like JECFA and EFSA have evaluated propyl gallate. Some studies have raised questions about potential health effects, but evidence is mixed and often based on high doses not typically consumed. At the levels used in food, it is generally considered safe by regulatory agencies.
