Popis: | In this study a specific taste-modulating flavor ingredient, N-lactoyl ethanolamine, was determined in two Beerenauslese wines using preparative LC, as a first isolation and concentration step, followed by LC-MS/MS on a triple quadrupole in accurate mass (AM) mode. The accurate masses of the analyte and three characteristic fragments were determined with mass accuracies between 8 and 20 ppm. N-lactoyl ethanolamine concentrations in the wines were 0.4 and 2.5 mg/L. |
