E307 - Alpha-tocopherol (synthetic)


Group: Acids, Antioxidants, Mineral salts

Description:
Vitamin E, known as the anti-sterility vitamin - from the Greek tokos (child) and pherein (bear), is fat-soluble and is a mixture of alpha-, beta-, gamma- and delta- tocopherols. Although eight chemically similar substances have Vitamin E activity, alpha-tocopherol is the most active of these with 100%, followed by beta- (15-40%), gamma- (1-20% then delta (1%). Found in most foods, it is abundant in, amongst other things, whole grain cereals, corn and cottonseed oils, egg yolks, meat and milk. E307 is an antioxidant and is used in pork pies and sausages as well as a vitamin supplement. Has a greater antioxidant effect than gamma-tocopherol (E308) in animals but not in cells or non-biological matter. It also protects other nutrients, such as Vitamin A, from oxidation but is largely destroyed by freezing. Commercially it can be produced from cottonseed, maize, rice germ, soya been oil, wheat germ, or green leaves and may, therefore, come from Genetically Modified sources.

Animal origin: No
