Comparing E210 - Benzoic acid vs E233 - Thiabendazole

Overview

E210 - Benzoic acid

Benzoic acid (E210) is a preservative used to help keep acidic foods and drinks safe and fresh by slowing the growth of yeasts, molds, and some bacteria. It occurs naturally in small amounts in some berries and fermented foods, and is also made for food use under strict purity standards.

E233 - Thiabendazole

Thiabendazole (E233) is a synthetic fungicide from the benzimidazole family. In food, it has been used mainly as a post‑harvest surface treatment to stop molds on fruit, rather than as an ingredient mixed into recipes. You’re most likely to encounter it on the peel of certain imported fruits rather than inside packaged foods.

  2. Is benzoic acid polar?

    It has a polar carboxyl group but a nonpolar aromatic ring, so overall it’s only weakly polar; its benzoate salt is much more polar and water‑soluble.

  3. Is benzoic acid a strong acid?

    No—it's a weak acid, with a pKa of about 4.2.

  4. What is the melting point of benzoic acid?

    About 122–123 °C (251–253 °F).

  5. Is benzoic acid bad for you?

    At approved food levels it’s considered safe, with an ADI of 0–5 mg/kg body weight/day; some people may experience irritation or hypersensitivity, and benzene formation in certain acidic drinks is monitored and kept very low.
