The α-diketones glyoxal, methylglyoxal, and diacetyl were determined in selected beer and wine using a procedure involving the use of C 18 solid phase extraction columns to remove interferences and derivatization of the compounds with ophenylenediamine to form quinoxalines, which are separated by HPLC and detected using UV spectrophotometric detection.

The determination was easier to implement in the case of wine as the typical concentrations of the compounds were about ten times higher, with methylglyoxal being the more abundant compound found.
