Butylated Hydroxyanisole (BHA)
CAS Number: 25013-16-5
Butylated hydroxyanisole (BHA, E320) is a synthetic lipid-soluble antioxidant used to retard rancidity and oxidative deterioration in fats, oils, and fat-containing foods. It is particularly effective in lard, butter, and fried snack foods, with carry-through stability into baked and fried products. Supplied as white to slightly yellow waxy solid with ≥98.5% purity; often used in combination with BHT for synergistic effect.
