Benzoesäure in der Lebensmittelkonservierung

Benzoic acid and its salts (E210–E213) are widely used preservatives that inhibit mold, yeast, and bacteria in juices, soft drinks, pickled and acidic foods, and cosmetics. Beyond preservation, the compound serves as a precursor for plasticizers, alkyd resins, caprolactam, dyes, and pharmaceuticals, with regulatory limits ensuring safe use.
