TBHQ is a highly effective antioxidant. In foods, it is used as a 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).It is added to a wide range of foods, with the highest limit (1 gram/kg) permitted for frozen fish and fish products. Its primary advantage is enhancing storage life.
