What is Food Additive E 306 ?
E306, also known as Tocopherol-Rich Extract , is a natural antioxidant. It is extracted from vegetable oils rich in vitamin E, but it can also be produced synthetically. Tocopherols are a group of organic compounds known for their antioxidant properties, helping protect cells against damage caused by free radicals.
E306 is derived from vegetable oils, particularly from soybean, corn, and sunflower oils. It is widely used in the food industry to extend the shelf life of products by preventing the oxidation of fats and oils, which can cause rancidity.
E306 plays a crucial role in maintaining the quality and safety of processed foods. Oxidation is a chemical reaction that occurs when foods are exposed to oxygen, leading to the deterioration of fats and oils. This process not only affects the taste and smell of foods but can also lead to the formation of harmful compounds.
By incorporating food additive E306 into food products, manufacturers can slow down the oxidation process, ensuring that foods remain fresh and edible for longer periods.

Contraindications and Risks
There are no concerns that tocopherols are genotoxic or carcinogenic. There is insufficient data to address toxicity related to reproduction and development. However, some concerns have been raised regarding the widespread use of E306:
- Allergies: Since E306 is often derived from soy and other common allergens, people with allergies to these substances should be cautious.
- Overconsumption: Although vitamin E is beneficial, excessive consumption can lead to health problems. High doses of vitamin E supplements have been linked to an increased risk of bleeding due to its blood-thinning properties. However, the amounts used in food products are usually too small to pose such risks.
- Environmental Impact: The production of E306, like other food additives derived from vegetable oils, can contribute to environmental concerns related to large-scale agriculture.
In conclusion, E306 is a valuable food additive that extends the shelf life of various products while also providing significant health benefits due to its high vitamin E content. Although it is generally considered safe, consumers should be aware of potential allergic reactions and its environmental impact.
