Alike in case of other spirits, specific sensory properties of plum brandies, which are associated with aromatic compounds pattern, depend not only on a fruit quality but also on technol. used for raw material processing. In this study, novel approach based on the non-target screening of (semi)volatile compounds by gas chromatog. coupled to high-resolution mass spectrometry (GC-HRMS) was employed. The potential of this approach to distinguish plum brandies of different origin was investigated. To involve as many compounds as possible for assessment, three different sample handling strategies prior to instrumental anal. were tested: (i) no pre-treatment direct sample injection, (ii) liquid-liquid extraction by Et acetate, (iii) extraction of volatiles by head-space solid-phase microextraction (HS-SPME). The latter approach was selected for obtaining GC-HRMS volatiles fingerprints of a unique set of 41 plum brandy samples produced by the distilleries from Czech Republic and from Bulgaria. Multivariate statistical data anal. enabled construction of chemometric models for unbiased authentication of plum brandies, moreover, distinguishing between premium plum brandies and other ones from the Czech Republic was achieved. In addition, volatile compounds such as p-cymene, Me eugenol and furfural were identified among the most significant ‘markers’ responsible for reliable classification of the samples. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1COA of Formula: C10H20O2).
Octyl acetate (cas: 112-14-1) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
