E308: Gamma-Tocopherol
Main role: fat oxidation control
Also listed as: γ-tocopherol, gamma tocopherol
What is E308 (Gamma-Tocopherol)?
Gamma-tocopherol E308 is a tocopherol used as an antioxidant in food systems containing fats. It is a different molecular form from alpha-tocopherol E307 and delta-tocopherol E309. A manufacturer may choose among these forms for their performance in a specific formulation.
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.
Food and formulation examples
- Edible fats
- Oil-based food preparations
- Antioxidant blends
These examples describe formulation roles, not a list of unrestricted legal uses. Availability and permitted applications differ by country and food category.
Label names and ingredient questions
Look for E308, E 308, or the ingredient name. Related names and label terms include γ-tocopherol, gamma tocopherol. A family code can cover more than one specified form; check the full declaration when the distinction matters.
The word tocopherol can refer to several forms. Keep gamma-tocopherol distinct from alpha-tocopherol when reading an antioxidant specification or comparing nutrient claims.
Is E308 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 E308 as Gamma-tocopherol. 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.
