E306: Tocopherol-Rich Extract
Main role: fat oxidation control
Also listed as: mixed tocopherols, natural mixed tocopherols
What is E306 (Tocopherol-Rich Extract)?
Tocopherol-rich extract is a mixture of tocopherols used to slow oxidation in fats and oils. It is typically obtained from vegetable-oil processing streams. A mixed extract is different from an isolated alpha-, gamma-, or delta-tocopherol preparation.
What does it do in food?
Its main role is fat oxidation control. An antioxidant additive helps manage oxidation within the food, such as changes in fat, flavor, or color. That technical role is separate from claims that eating the ingredient will provide a particular health benefit.

Label names and ingredient questions
Look for E306, E 306, or the ingredient name. Related names and label terms include mixed tocopherols, natural mixed tocopherols. A family code can cover more than one specified form; check the full declaration when the distinction matters.
Mixed tocopherols on a food label usually signal an antioxidant role. Do not calculate a vitamin E supplement dose from that listing; the composition and added quantity are not shown.
Is E306 safe?
There is no meaningful personal risk estimate from an E number alone. Food-grade specifications, allowed uses, amount consumed, and individual circumstances all matter. The authorization record below gives the legal scope; it is not a claim that every possible use is appropriate.
A label identifies the ingredient but usually not its concentration. Calculating daily intake requires the amount in the food and the quantities eaten.
Authorization and conditions of use
The Great Britain food additive register lists E306 as Tocopherol-rich extract. This is an entry subject to its stated conditions, not unrestricted permission for every food. The record links to the applicable authorization terms. For an EU product, use the European Commission food additive database to check the relevant food category and limits. Other countries may use different names or rules.
