Warmed-over flavor can be prevented by the addition of preservatives to processed meat. Many of the preservatives are antioxidants, ranging from tocopherols (related to vitamin E) to plum juice to industrial additives such as butylated hydroxytoluene (BHT), butylated hydroxyanisole (BHA) and propyl gallate.[1] Other preservatives such as sodium pyrophosphate and sodium hexametaphosphate may work by binding iron and preventing it from catalyzing the chemical reactions which lead to warmed-over flavor; as these compounds are generally more soluble in water than the fat-soluble antioxidant preservatives, they may be more readily used to prevent oxidative decomposition in meat.[2] Nitrites, a curing agent for meat, may prevent the development of warmed-over flavor by preventing the release of iron during cooking
