Benzoic acid has a pronounced property of inhibiting the growth and development of mold, some types of bacteria and yeast, manifests itself as an antimicrobial agent. Naturally found in cranberries and cranberries, the industrial method for producing E210 is the oxidation of toluene using catalysts.
The harm of E210 Benzoic acid

It is dangerous to health, can cause rashes and provoke asthma attacks. The substance is well absorbed into the body, is excreted through the kidneys in the urine.
