E392 is a designation given to a mixture of tocopherols, which are a group of fat-soluble compounds that include four distinct forms alpha, beta, gamma, and delta tocopherol. These tocopherols are primarily extracted from natural sources, particularly from sunflower, soybean, and palm oils. E392 serves as a food preservative, helping to prevent the oxidation of food products, which can lead to spoilage and rancidity. By acting as an antioxidant, E392 helps to extend the shelf life of various food items, such as baked goods, snacks, and cooking oils.
