title: Fluorometric determination of biacetyl.
abstract: The fluorometric determination of biacetyl is described. 3,4-Diaminoanisole reacts with biacetyl in alkaline ethanol-water solution to give strongly fluorescing 2,3-dimethyl-6-methoxy-quinoxaline. Variables such as solvent composition, quenching by acetic and sulphuric acid, heating time and interference by other carbonyl compounds present are discussed. The method may be suitable for the determination of biacetyl in foodstuffs.
