Comparing E321 - Butylated hydroxytoluene vs E324 - Ethoxyquin

Overview

E321 - Butylated hydroxytoluene

Butylated hydroxytoluene (BHT), also known as E321, is a synthetic antioxidant added to foods to keep fats and oils from turning rancid. It helps protect flavor and aroma, and it can extend shelf life in products that contain fat or oil. It is permitted for use in many countries under strict limits.

  2. Is bht bad for you?

    Major regulators (FDA, EFSA, JECFA) consider BHT safe at permitted levels, with an acceptable daily intake around 0.25–0.3 mg/kg body weight/day. High doses in animal studies have caused liver/thyroid effects, but evidence of harm at normal food-use levels in humans is limited.

  3. What is bht in cereal?

    It’s an antioxidant preservative used to keep the cereal’s fats from going rancid; in some products it’s applied to the packaging liner rather than the cereal itself to help preserve freshness.

  4. What is bha and bht?

    BHA (E320, butylated hydroxyanisole) and BHT (E321, butylated hydroxytoluene) are synthetic antioxidants used to slow the oxidation of fats and oils in foods, helping preserve flavor and shelf life.

  5. What is bht and why you should avoid it?

    BHT is a synthetic antioxidant used to prevent rancidity and preserve freshness. It’s considered safe at regulated levels, but some people choose to avoid it due to its synthetic origin or concerns from high-dose animal studies.
