Butylated hydroxyanisole

Antioxidant, the antioxidant effect of 3-bha added in food is 1.5-2 times stronger than that of 2-bha, but the mixture of the two has a certain synergistic effect. Therefore, the effect of the mixture containing high proportion of 3-bha is almost similar to that of pure 3-bha. BHA can react with peroxide produced in the process of oil oxidation to cut off the chain reaction of oil automatic oxidation and prevent oil from further oxidation. When BHA is mixed with other antioxidants and synergist citric acid, its antioxidant effect is more significant. In addition to antioxidant activity, BHA also has strong antibacterial activity and anti mildew effect. As a food additive, it is used as an antioxidant in oil, lard, salted fish and shellfish products, dried fish and shellfish products, pretzels, fried potato slices, instant noodles, fried snacks, etc. It is also used as feed additive and gasoline additive. 3-tert-butyl-4-hydroxyanisole (2-bha) is also used as a biochemical reagent.
