Le benzoate de potassium, de formule chimique (C6H5COOK) est le sel de potassium de l'acide benzoïque, présenté sous forme de poudre cristalline blanche. L'acide benzoïque est un produit naturel présent dans certains fruits comme les canneberges ou airelles. Le benzoate de potassium est utilisé, entre autres, comme conservateur alimentaire et est référencé en Europe sous le code E212. Potassium benzoate (E212), the potassium salt of benzoic acid, is a food preservative that inhibits the growth of mold, yeast and some bacteria. It works best in low-pH products, below 4.5, where it exists as benzoic acid.

Acidic foods and beverages such as fruit juice (citric acid), sparkling drinks (carbonic acid), soft drinks (phosphoric acid), and pickles (vinegar) may be preserved with potassium benzoate. It is approved for use in most countries including Canada, the U.S., and the EU, where it is designated by the E number E212.

Potassium benzoate is also used in the whistle in many fireworks. One very common way to make potassium benzoate is by oxidizing toluene to benzoic acid followed by a neutralization with potassium hydroxide.[4] An way to synthesize potassium benzoate in the lab setting is by hydrolyzing methyl benzoate with potassium hydroxide. Potassium benzoate, the potassium salt of benzoic acid, is typically used by food manufacturers as a chemical preservative. It's sometimes used in place of a related preservative -- sodium benzoate -- to reduce the food's sodium content. Potassium benzoate helps fight food spoilage, and it can contribute to food's flavor, but like any food additive, it can cause allergic reactions in some people. Potassium benzoate -E212-, the potassium salt of benzoic acid, is a food preservative that inhibits the growth of mold, yeast and some bacteria. It works best in low-pH products, below 4.5, where it exists as benzoic acid. Acidic foods and beverages such as fruit juice -citric acid-, sparkling drinks -carbonic acid-, soft drinks -phosphoric acid-, pickles -vinegar-, and frogurt toppings may be preserved with potassium benzoate. It is approved for use in most countries including Canada, the U.S., and the EU, where it is designated by the E number E212. Potassium benzoate is also used in the whistle in many fireworks.
