Fruit and vegetable products — Determination of benzoic acid content (benzoic acid contents greater than 200 mg per litre or per kilogram) — Molecular absorption spectrometric method

Produits dérivés des fruits et légumes — Détermination de la teneur en acide benzoïque (Teneurs supérieures à 200 mg par litre ou par kilogramme) — Méthode par spectrométrie d'absorption moléculaire

Abstract / scope

The method consists in extracting the acid from an acidified test portion using diethyl ether, nitrating followed by reduction and Mohler's reaction modified with hydroxylaminehydrochloride, measuring the absorbance of the red complex obtained with a suitable spectrometer. For determining lower concentrations, see ISO 5518.
