Most components identified in samples (A) and (B) were also investigated in the analyzed grape oils (C)–(I), respectively. Trans-2-Hexenal and trans-2-heptenal representing flavour active compounds formed by enzymatic actions are known to provide fruity, green, leafy notes and were detected in the majority of grape oils, as well as components like hexanoic acid, trans-2-hexenal, heptanal and 2-heptanone with comparable amounts in both groups of oils (refined and unrefined).
