Compare E210 vs E544, Benzoic acid vs Calcium polyphosphate

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.

E544 - Calcium polyphosphate

Calcium polyphosphate (E544) is a member of the phosphate family used to stabilize texture, bind water, and control acidity in processed foods. It belongs to the broader “polyphosphates” group, which helps foods like processed cheese and cured meats hold together and stay moist.

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.
