Abstract

A method for the determination of furanic compounds intraditional balsamic vinegars is proposed. It is based on ionexclusion chromatographic separation and diode-array detection of furans through an isocratic elution with 0.01N phosphoric acid and 16% acetonitrile. Preliminary trials on standard compounds stability in heat–acidic conditions are also performed. In all the 19 samples analyzed, 2-furoic acid, 5HMF, and furfural are found.No sample contains 4-hydroxy-2,5-dimethyl-3-(2H)-furanone(DHMF); 2-acetylfuran; or furfuryl alcohol. Three Unknown compounds are also detected. The last eluting of these compoundsis identified as 5-acethoxymethylfurfural, and, notwithstanding apartial hydrolysis in our chromatographic conditions, itsquantitation can be carried out.
