Fig. 6

The nodes represent the annotated ions with given sum formulae or molecule names. They are connected by edges representing the sum formula differences for the hops rich beer-type markers (a) and the biochemical reaction for the wheat grain markers (b), respectively. All nodes depicted are considered marker substances. Wheat grain markers are additionally characterized by UPLC-MS2 of wheat beer sample 41 with literature matching retention time order and MS2-spectra showing respective fragmentation and mass difference pattern (c)32,39.
