E309 - Delta-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. E309 is an antioxidant for polyunsaturated fatty acids as well as a vitamin. Reported to be the most effective antioxidant of all the tocopherols in 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
