Its primary use is as a fat-soluble antioxidant food additive. BHA is used to preserve fats and oils in food, cosmetics, and pharmaceuticals. It prevents rancidification by reacting with oxygen before oxygen has a chance to react with fats and oils, thus slowing the development of off-flavors, odors, and color changes caused by oxidation. Some foods in which BHA is used include: butter, meats, cereals, chewing gum, baked goods, snack foods, dehydrated potatoes, and beer.
