tert-Butylhydroquinone (TBHQ, tertiary butylhydroquinone) is an aromatic organic compound which is a type of phenol. It is a derivative of hydroquinone, substituted with tert-butyl group.
TBHQ is a highly effective preservative for unsaturated vegetable oils and many edible animal fats. It does not cause discoloration even in the presence of iron, and does not change flavor or odor of the material to which it is added. It can be combined with other preservatives such as butylated hydroxyanisole (BHA). As food additive, its E number is E319, where it is used as a preservative. It is added to a wide range of foods, with highest limit (1000 mg/kg) permitted for frozen fish and fish products. Its primary advantage is enhancing storage life.
