Summary Furfural and Hydroxymethylfurfural can easily be determined in alcoholic beverages by means of reverse phase chromatography. A special sample preparation is not necessary. The aldehydes are detected by UV-spectrometry, the absolute detection limit in routine work is 4–7 mg/100 liters of pure ethanol (corresponding to 0.016–0.03 mg/l beverage) and can be extended down to 0.002–0.001 mg/l when injecting higher volumes for trace analysis. In the range of 0.25–3 mg/l linear relationship is obtained between peak hight and concentration. The complete assay procedure takes about 12 min. A series of Brazilian Cachaça samples and German commercial liquors were investigated with the here described method. |
