E306: Tocopherol-rich extract

What is E306?

Tocopherol-rich extract (E306) is a natural mixture of tocopherols, the compounds that make up vitamin E. These fat-soluble molecules protect oils and fats from reacting with oxygen and turning rancid.

Origin and production

It is obtained from vegetable oils, typically soybean, sunflower or rapeseed oil, by concentrating the tocopherols from by-products of oil refining.

Why is it used?

Manufacturers add it as an antioxidant to protect fats in breakfast cereals, muesli, cereal bars, biscuits, snacks and oils, helping to extend shelf life and preserve flavour. It is often favoured because it comes from natural sources.

Vegan, vegetarian and halal

Tocopherol-rich extract is plant-derived and suitable for vegans and vegetarians. It does not usually raise halal or kosher concerns. If derived from soy, highly refined forms are generally exempt from EU allergen labelling.

Safety and regulation

Tocopherol-rich extract is authorised as a food additive in the EU and was re-evaluated by EFSA along with other tocopherols, without a safety concern at reported uses. It is permitted in many foods at levels consistent with good manufacturing practice.
