Food additive E 210

What is benzoic acid?

Blueberries are rich in benzoic acid

Benzoic acid (E 210) is a natural preservative, an organic acid, found in small amounts especially in cloves, blueberries, raspberries, red currants, plums and also in milk, honey and berries (among other foods), which is extracted from the fruits of the rowan tree; and that can also be synthesized.

Chemical properties of benzoic acid

It is an organic acid with bactericidal and inhibitory action on the growth of fungi and yeasts.

However, on an industrial level it is used as a preservative mainly because it basically acts against fungi and yeasts and to a lesser extent against bacteria. To increase its antibacterial effectiveness, it is usually combined with sodium chloride, acetates and sulfites (E 200).

Uses of benzoic acid in the food industry

Its use is limited by its spicy and metallic taste that it leaves in food.

This flavor is softened in acidic foods, which is why the greatest application is in canned fruits and vegetables, juices and carbonated soft drinks.

What products contain benzoic acid?

  • This food preservative is used in: non-alcoholic draft beer, spirits, low-sugar jams, jams, jellies, olives, meat or fish jellies.
  • In combination with sorbic acid (E 200) it is used in: candied fruits, fermented and pickled or salted vegetables; canned fish, dried fish, other fish products, prawns, chewing gum, diet products, wine.
