- •
First UHPLC simultaneous analysis of biogenic amines and precursors in beer.
- •
9 biogenic amines, 22 amino acids and ammonium ions determined in 14 min.
- •
The method is sensitive and precise, and no matrix effect was found.
- •
Ethanolamine was found for the first time in beer (in all the samples).
- •
The method could be used for monitoring the safety and quality of beers.
