Butylhydroxyanisole (BHA), also known as tert butyl-4-hydroxyanisole, has the chemical formula C11H16O2 and two isomers: 3-BHA and 2-BHA, generally referring to a mixture of the two.
Butyl hydroxyanisole, as a fat soluble antioxidant, is suitable for oily and fat rich foods. Due to its good thermal stability, it can be used under frying or roasting conditions. In addition, butyl hydroxyanisole has a strong antioxidant effect on animal fats, while its antioxidant effect on unsaturated plant fats is poor. Butyl hydroxyanisole can stabilize the pigment of raw beef and inhibit the oxidation of ester compounds.
