Comprehensive analysis of dipeptides in alcoholic beverages by tag-based separation and determination using liquid chromatography/electrospray ionization tandem mass spectrometry and quadrupole-time-of-flight mass spectrometry

► A separation method of AQC-derivatized dipeptide was developed by UHPLC using two sub-3μm core-shell type columns. ► Quantification and structural estimation of dipeptide using MS/MS and Q-TOFMS were examined. ► Dipeptide content in alcoholic beverages was quite differ among Japanese sake, beer, a...
