Butylated hydroxytoluene (BHT) is a food additive which is used as a preservative, and when it appears on food labels, it indicates that the manufacturer is concerned about the potential for the food to go rancid. BHT is also used as a preservative in a number of other things, ranging from cosmetics to jet fuel. The substance was developed in the late 1940s, and approved for use in the 1950s.This substance is an antioxidant, preventing oxidation damage to fats. When foods which are high in fat are not treated with preservatives, the fats can go rancid very quickly, causing the fats to taste bad, and potentially creating health risks for consumers. By using preservatives like BHT, manufacturers can ensure that their foods are shelf-stable longer, and that their flavors will be retained. Essentially, BHT intercepts free radicals, preventing them from attacking the fats.
