Mixed tocopherols are found in soya beans and contain d-alpha-tocopherol (commonly known as vitamin E), beta-tocopherol, gamma-tocopherol and delta-tocopherol, hence the name "mixed tocopherols".
Many foods contain lipids, and when lipids oxidize, they give rise to a characteristic rancid smell and taste. Oxidation of lipids can also decrease their nutritional quality and safety. It is therefore important to prevent or at least slow down this oxidation process to ensure healthy food products with a long shelf life that taste and smell good. Mixed tocopherols are strong antioxidants and are used in foods to slow down the oxidation of lipids.
