Widely used as an antioxidant in animal feed, particularly in poultry and fish farming, to prevent oxidation of fats and fat-soluble vitamins, thereby preserving nutritional value and extending shelf life. Commonly added to fishmeal to maintain quality during storage and transport. Also used in the rubber industry to protect against oxidative degradation and improve durability. Limited use in some fruit coatings to prevent oxidation, though this application is restricted in many countries due to safety concerns.
