Characterization of volatile compounds of "Drenja", an alcoholic beverage obtained from the fruits of cornelian cherry

Abstract

In this study, volatile compounds were analyzed in five samples of home-made spirit beverage made by the distillation of fermented fruits of cornelian cherry (Cornus mas L.). The major volatile compounds, besides ethanol, identified and quantified were: methanol, acetaldehyde, I-propanol, ethyl acetate, 2-methyl-1-propanol, 1-butanol, amyl alcohols, 1-hexanol and 2-phenyl-ethanol, The minor volatiles were submitted to liquid liquid extraction with dichloromethane and analyzed by gas chromatography and gas chromatography/ /mass spectrometry (GC/MS). A total of 84 compounds were identified. The most abundant compounds were straight-chain free fatty acids, ethyl esters of C(6)-C(18) acids, limonene, 2-phenylethanol and 4-ethylphenol. Most of the compounds found in the "Drenja" spirits investigated in this study arc similar to those present in other alcoholic beverages.

U radu su analizirane isparljive komponente u pet uzoraka alkoholnih pića, domaće izrade, dobijenih destilacijom fermentisanih plodova drenjine (Cornus mas L.). Glavna isparljiva jedinjenja, koja su određena i kvantifikovana, su: metanol, 1-propanol, etil-acetat, 2-metil-1-propanol, 1-butanol, izoamil-alkoholi, 1-heksanol i 2-feniletanol. Manje zastupljena isparljiva jedinjenja su ekstrahovana dihlormetanom i analizirana kombinacijom gasne hromatografije i masene spektrometrije (GC/MS). Identifikovana su ukupno 84 jedinjenja. Najzastupljenija jedinjenja bila su etil estri masnih kiselina sa C6-C18, slobodne masne kiseline, limonen, 2-feniletanol i 4-etilfenol. Većina jedinjenja nađena u 'drenji' su slična onima koja su prisutna i u drugim alkoholnim pićima.
