Tocopherols in dog food
Tocopherols (part of the vitamin E family of compounds) are powerful antioxidants and are the most commonly used natural preservative in dog food. As antioxidants, tochopherols are able to slow down the spoilage of food by inhibiting the oxidisation that turns fats rancid. Their use is extremely widespread in the UK as it provides a convenient, healthy alternative to potentially harmful chemical preservatives.
