Tocopherols And TBHQ As Preservatives

Tocopherols are a group of compounds related to vitamin E. TBHQ (tert-Butylhydroquinone) is a synthetic antioxidant. They are often used together to prevent fats and oils in foods from spoiling.

Tocopherols and TBHQ are added to foods as antioxidants to prevent rancidity and extend shelf life. They are commonly found in products with high fat content, such as baked goods, vegetable oils, and snack foods.

In the US, tocopherols are generally recognized as safe (GRAS) when used as preservatives. TBHQ is also permitted as a food additive by the FDA. Regulatory bodies like the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated these substances. While generally considered safe at permitted levels, some studies have explored potential effects at very high doses, though evidence is mixed and not conclusive for typical dietary intake.
