E306 = Vitamin E
E306 is an additive approved by the EU (European Union). It is used as a natural antioxidant in food and drink products.
The common name for E306 is tocopherol-rich extract, otherwise known as Vitamin E.
The antioxidant E306 is obtained by extraction from vegetable oils, such as wheat and rice germ, and can help prevent oxidation of Vitamin A. Its application to food products is limited by its strong flavour.
Vitamin E is important in fertility and reproduction, as well as being involved in the formation of red blood cells. It also acts to protect cell membranes from oxidation. Excessive doses of vitamin E may cause side effects, such as blurred vision and headaches.
Examples of food and drink products that may include E306:
- animal and vegetable oils
- animal and vegetable fats
- salad dressings
