Propyl Gallate Preservative

Propyl gallate is a synthetic antioxidant. It is made by combining gallic acid with propanol. It is used to prevent oils and fats in foods from becoming rancid.

Manufacturers add propyl gallate to foods to act as a preservative, specifically to prevent fats and oils from spoiling. It is often found in baked goods like cakes, pastries, and muffins, as well as in snack foods and processed meats.

Propyl gallate is generally recognized as safe (GRAS) by the FDA when used as a food additive. Regulatory bodies like JECFA and EFSA have evaluated propyl gallate, and it is permitted for use in many countries. Some studies have raised questions about potential allergic reactions or other health effects, but the evidence at typical consumption levels is mixed and not considered a significant concern by major regulatory agencies.
