Butylated Hydroxytoluene (BHT)
CAS Number: 128-37-0
Butylated hydroxytoluene (BHT, E321) is a synthetic phenolic antioxidant used in edible oils, animal fats, chewing gum, and packaging materials to prevent lipid oxidation and rancidity. It exhibits excellent stability at elevated temperatures, making it effective in deep-frying oils and baked snack goods. Maximum permitted levels are typically 200 mg/kg in fats and oils (EU). Available as white crystalline flakes or powder.
