Butylated hydroxyanisole (BHA) is a food additive commonly used as an antioxidant to prevent the spoilage of fats and oils and extend the shelf life of various processed foods. BHA is produced through a chemical synthesis process in which aniline, a benzene derivative, is reacted with isobutylene, resulting in the formation of tert-butyl 4-methoxyphenol. The compound is then converted to Butylated hydroxyanisole through a hydroxylation reaction using sodium hydroxide or other alkali agents. BHA appears as a white or yellowish crystalline powder and is added to food products in specific concentrations to prevent oxidation and maintain their quality. It is commonly found in packaged goods like Frosted Flakes, Stove Top Stuffing, Honey Bunches of Oats, Wheat Thins, Farmer John Breakfast Sausage Links, and Rice Krispies.
