Origin
Delta-Tocopherol is synthesized from the starting substance Tocopherol through a chemical process. In this process, it is also possible that E 309 can be produced with the help of genetically modified organisms.
Usage
The use of E 309 as an antioxidant has no approval restrictions and the same conditions apply as for E 306, E 307, and E 308. However, unlike E 306, E 309 is not approved for Bio products. Delta-Tocopherol is used in the following foods: Oils and margarines, fats, infant formula, chewing gum, dressing, and desserts.
Risks
The use of E 309 is considered completely harmless. At very high dosages of Tocopherol, certain negative symptoms such as metabolic disorders can occur. However, as an antioxidant, E 309 is never added to food in corresponding high doses. This warning applies primarily for additional Tocopherol intake through dietary supplements.
