Purpose and Function

Octyl Gallate (E311) is used in the food industry as an antioxidant. It helps to prevent the oxidation of fats and oils, extending the shelf life of food products and preventing rancidity. It is often used in combination with other antioxidants like BHA (E320) and BHT (E321). Common applications include:

  • Oils and fats: Added to cooking oils, margarine, and butter to prevent spoilage.
  • Snack foods: Used in fatty snacks like chips and nuts to delay the oxidation of fats.
  • Baked goods: Helps preserve freshness in pastries, cakes, and other baked products containing fats.
  • Processed meats: Used to prevent fat oxidation in products such as sausages and other meat products.
  • Cosmetics and pharmaceuticals: Besides food, it is also used in non-food products to stabilize fats and oils.

Octyl Gallate (E311) is effective at protecting products from spoilage, especially those containing fats and oils.


Potential Risks and Side Effects

Octyl Gallate (E311) is generally considered safe when used within regulated limits, but there are some considerations:

  • Allergic reactions: Some individuals may experience allergic reactions, such as skin rashes or gastrointestinal discomfort, although these cases are rare.
  • Possible toxicity: At very high doses, some studies have indicated potential adverse effects, though such levels are well above those found in regulated food products.
  • Regulatory approval: Octyl Gallate (E311) is approved for use in many countries, including the European Union, with strict usage limits to ensure safety.

While Octyl Gallate (E311) is effective as an antioxidant, its use is carefully regulated to ensure safety in food products.
