THE DETERMINATION OF AROMA PROFILE OF FRESH GRAPE BOGMA
Abstract
In this study, Bogma as a traditional alcoholic beverage in Hatay province was produced from fresh grape in laboratory conditions based on the traditional methods. The final product was analyzed for volatile compounds and the aroma profile. For this purpose, fermentation and distillation were carried out using clay pots, copper made pots as traditional methods, respectively. Volatile compounds were determined by gas chromatography-mass spectrometry (GC-MS), whereas aroma active compounds were determined by gas chromatography-olfactometry (GC-O). According to the results; Bogma samples consisted of 40 to 50% (v/v) of ethanol, 5.8 and 16.8mg/100mL mA of total volatile substances and had a density of 0.9309 and 0.9488 g/cm3. Furfural was not present in the samples and there were 43 volatile compounds (12 esters, 18 terpenes, 4 higher alcohols, 1 aldehyde, 3 phenolic compounds, 1 primary alcohol, 1 ketone and 4 other unknown volatiles).Of the 43 compounds, 27 volatiles were identified in GC-MS that 18 were identified in both GC-MS and GC-O and 26 were identified as aroma active compounds. Of which, 8 were detected only at the sniffing port.
