Comparing E210 - Benzoic acid vs E263 - Calcium acetate

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.

E263 - Calcium acetate

Calcium acetate (E263) is a calcium salt of acetic acid used in foods to control acidity, help preserve freshness, and support texture. It is commonly found in bakery items and other processed foods where a mild acid and a source of calcium are useful. Safety reviews by regulators consider its approved uses to be acceptable.

Popular questions

  1. Is benzoic acid soluble in water?

    Only sparingly—about 3 g per liter at room temperature; its solubility increases in hot water and it dissolves readily in many organic solvents.

  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.

  1. What is calcium acetate used for?

    As a food additive (E263), it’s used as a preservative and stabilizer to inhibit mold growth, help maintain texture, and can aid in buffering acidity in foods.

  2. Is calcium acetate soluble in water?

    Yes—calcium acetate is highly soluble in water; it is poorly soluble in ethanol.

  3. What is the formula for calcium acetate?

    Ca(C2H3O2)2; the common commercial form is the monohydrate, Ca(C2H3O2)2·H2O.

  4. Calcium acetate 667 mg para que sirve?

    Como aditivo alimentario (E263), se usa como conservante y estabilizante para frenar mohos y ayudar a mantener la textura. En medicina, el comprimido/cápsula de 667 mg se usa como quelante de fosfato en enfermedad renal crónica.

  5. Calcium acetate para que sirve?

    Como aditivo alimentario (E263), sirve de conservante y estabilizante, ayudando a controlar la acidez y la textura de los alimentos. Fuera del ámbito alimentario, también se usa como quelante de fosfato en pacientes con enfermedad renal.
