Description and Uses
Butylated hydroxytoluene (BHT) is a synthetic antioxidant. It scavenges peroxide, 2,2-diphenyl-1-picrylhydrazyl (DPPH; ), superoxide, and ABTS radicals in cell-free assays, as well as inhibits lipid peroxidation of linoleic acid in vitro when used at a concentration of 45 μg/ml. Butylated Hydroxytoluene (0.025-3.2 mM) reduces freeze-thaw-induced malondialdehyde (MDA) production and increases sperm viability in boar spermatozoa preparations. Formulations containing BHT have been used as antioxidant cosmetic and food additives.
Because they prevent rancidity, antioxidants are of great interest to the food industry. For example, butylated hydroxytoluene (BHT), butylated hydroxyanisole (BHA), and EDTA are frequently used to preserve various foods, such as cheese or fried products. Butylated hydroxytoluene is a powerful inhibitor of lipid peroxidation, yet large doses of it can induce oxidative DNA damage and cancer development in the rat forestomach.
