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.

E457 - Alpha-Cyclodextrine

Alpha-Cyclodextrine (E457) is a ring-shaped carbohydrate made from starch. In foods, it works mainly as a stabiliser and thickener, helping protect flavors and improve texture. You’ll usually see it on labels as “alpha-cyclodextrin” or “E457.”

Popular questions

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.
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.
Is benzoic acid a strong acid?
No—it's a weak acid, with a pKa of about 4.2.
What is the melting point of benzoic acid?
About 122–123 °C (251–253 °F).
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.
