“…Most of them characterized fruity and floral flavor such as 3-methylbutanol, benzyl alcohol, 2-ethylhexanol, 1-octanol, 1-nonanol, hexanal, octanal, benzeneacetaldehyde, nonanal, 2-phenylpropenal, 2,4-nonadienal, decanal, 2-decenal, dodecanal, butylphenyl methylpropional, (E)-3-penten-2-one, 2-heptanone, 6-methyl-5-hepten-2-one, acetophenone, 2-nonanone, 4-methylacetophenone, 2-decanone, 2-undecanone, 2-dodecanone, and 2-pentadecanone. Most of these compounds were previously identified in several studies of honey, elderberry fruits, and flowers (Jørgensen et al 2000;Baroni et al 2006;Pontes et al 2007;Kaack 2008;Kaack and Christensen 2008; Fig. 3 The example of tentatively identified nonanal extracted by the use of HS-SPME from the BOnisiówka^nalewka liqueur and analyzed through the GC×GC-TOFMS system.…”
