What is Benzoic Acid?
Benzoic acid is a naturally occurring aromatic carboxylic acid found in cranberries, prunes, cinnamon, and many berries. It is used as a preservative against bacteria, yeast, and fungi at pH below 4.5. In the body, benzoic acid is conjugated with glycine to form hippuric acid, which is excreted in urine.
Why is Benzoic Acid used in food?
Inhibits microbial growth in acidic foods and beverages such as soft drinks, pickles, fruit juices, and condiments.
Is Benzoic Acid dangerous? Documented risks
When benzoic acid (or sodium benzoate) is combined with ascorbic acid (vitamin C) in beverages, it can form benzene, a known carcinogen classified as Group 1 by IARC. This reaction is promoted by heat and light. The FDA and EFSA monitor benzene levels in beverages and have set informal guidance limits. A 1999 Lancet publication and the subsequent 2007 'Southampton study' did not directly involve benzoic acid, but sodium benzoate was included in the tested mixture. Some individuals with aspirin sensitivity may react to benzoic acid. The ADI is 5 mg/kg body weight/day.

How to avoid Benzoic Acid: safer alternatives
Potassium sorbate (E202), rosemary extract, and natural fruit acids provide alternative preservation options.
Frequently asked questions about Benzoic Acid
Does benzoic acid turn into benzene?
When combined with vitamin C (ascorbic acid) in an acidic beverage, especially with heat or light, benzene can form. The FDA monitors beverage benzene levels.
Is benzoic acid the same as sodium benzoate?
Sodium benzoate (E211) is the sodium salt of benzoic acid, both function as preservatives.
Is benzoic acid safe?
At permitted levels it is considered safe, but the benzene formation concern with vitamin C is a real, documented chemical reaction that warrants awareness.
Is benzoic acid natural?
Yes, it occurs naturally in cranberries, cinnamon, and cloves, but the food additive version is synthetically produced.
