Comparing E319 - Tertiary-butylhydroquinone (tbhq) vs E324 - Ethoxyquin

Overview

E319 - Tertiary-butylhydroquinone (tbhq)

Tertiary-butylhydroquinone (TBHQ), also known as E319, is a synthetic antioxidant used to keep fats and oils from going rancid. It helps foods stay fresh longer by slowing oxidation, which protects flavor, aroma, and color. Regulators in many countries allow TBHQ in small, controlled amounts.

E324 - Ethoxyquin

Ethoxyquin (E324) is a powerful synthetic antioxidant. Today it is best known for stabilizing fats and oils in animal feed rather than in everyday human foods. Its regulatory status differs by region, and some uses have been paused while more data are reviewed.

Popular questions

  1. What is tbhq in food?

    TBHQ (E319) is a synthetic antioxidant added to fats and oils to slow oxidation, helping prevent rancidity, off-flavors, and color loss in foods.

  2. Is tbhq bad for you?

    At the low levels allowed in foods, it’s considered safe by regulators; adverse effects have been observed only at much higher doses in animal studies, with an ADI of 0–0.7 mg/kg body weight/day.

  3. Tbhq what is it?

    TBHQ (tert‑butylhydroquinone) is a phenolic antioxidant preservative used to stabilize fats and oils in processed foods.

  4. What foods contain tbhq?

    It’s commonly used in vegetable oils and fat-rich processed foods such as snacks (chips, crackers), instant noodles, microwave popcorn, baked goods, and some fast‑food frying oils.

  5. How much tbhq is harmful?

    The acceptable daily intake is 0–0.7 mg per kg body weight per day (about 50 mg/day for a 70‑kg adult); regulations typically cap TBHQ at 200 mg/kg (0.02%) of the fat or oil, and adverse effects are linked to doses far above these levels.

  1. How to fix e324 error edd?

    E324 is the food-additive code for ethoxyquin, a synthetic antioxidant; an “E324 error” on an EDD system isn’t related to this additive—contact that service’s support for troubleshooting.

  2. What does e324 mean on edd?

    In food labeling, E324 means ethoxyquin; if you’re seeing “E324” as an error on an EDD platform, it’s unrelated to the additive and refers to that system’s own code.

  3. What is error e324 on edd?

    E324 denotes ethoxyquin in food-additive terms, not an EDD error; any “E324 error” on EDD is a system-specific code unrelated to the additive.

  4. Ethoxyquin what level is safe?

    Limits vary by region: in the U.S., ethoxyquin is allowed in certain spices at up to 100 mg/kg (100 ppm), while it isn’t authorized as a food additive in the EU; always check your local regulations.

  5. Ethoxyquin what level is safe paprika?

    In the U.S., ethoxyquin may be used in paprika up to 100 mg/kg (100 ppm) as a color preservative; it is not permitted as a food additive in the EU.
