What is Food Additive E308 ?
E308 is a food additive classified in the E300-E399 series, primarily associated with antioxidants. It is an important component in the food industry, especially for its role in preserving the quality and extending the shelf life of various products.
It is extracted from vegetable oils rich in vitamin E but can also be obtained synthetically.

E308 is predominantly used as an antioxidant in the food industry. Its main function is to prevent the oxidation of fats and oils, which can lead to rancidity, spoilage, and the development of unpleasant flavors.
By inhibiting oxidation, E308 helps maintain the freshness, flavor, and nutritional quality of food products, especially those with a high fat content, such as margarine, salad dressings, and snacks.
Beyond food, gamma-tocopherol is also used in the cosmetics industry, where it plays a similar role in preventing the degradation of fats and oils in skincare products.

Contraindications and Risks
There have been no significant health issues associated with the consumption of E308. In fact, tocopherols, including gamma-tocopherol, are essential for human health, contributing to the protection of cells against oxidative damage and supporting immune function.
While gamma-tocopherol is less potent than alpha-tocopherol in terms of vitamin E activity, it has unique antioxidant properties that are beneficial for health. Some studies suggest that gamma-tocopherol may be effective in neutralizing certain types of free radicals, which are involved in inflammatory processes and some chronic diseases.
In conclusion, E 308, or gamma-tocopherol, is an important food additive. It plays a crucial role in preserving the quality of foods, especially those rich in fats and oils. Beyond its role as a preservative, E308 contributes to human health as a form of vitamin E, offering protection against oxidative damage and supporting overall well-being.
With its proven safety and multiple benefits, E308 is a valuable component in the food industry.
