Abstract
Gin je jako, u pravilu bezbojno alkoholno piće dobiveno aromatiziranjem etilnog alkohola poljoprivrednog podrijetla bobicama borovice i drugim biljkama. Minimalni udio alkohola u ginu je 37,5% vol. Cilj ovog rada bio je utvrditi i usporediti profil hlapljivih spojeva četiri različita uzorka gina. Hlapljivi spojevi izolirani su mikroekstrakcijom vršnih para na čvrstoj fazi (HS-SPME), koristeći dva vlakna različite polarnosti, a identificirani vezanom tehnikom plinska kromatografija-spektrometrija masa (GC- MS). Identificirano je ukupno 37 hlapljivih spojeva iz skupina terpena, terpenoida, estera i fenilpropana. 14 spojeva je pronađeno u svim uzorcima, od kojih je 13 već prije identificirano u eteričnom ulju borovice (Juniperus communis). Etil-acetat koji je identificiran u svim uzorcima predstavlja sastavni dio destiliranih pića koji nastaje za vrijeme alkoholne fermentacije esterifikacijom etanola i octene kiseline. Razlike u aromatskim profilima uzoraka posljedica su različite recepture i proizvodnih procesa
Abstract (english)
Gin is a generally colourless spirit produced by flavouring ethyl alcohol of agricultural origin with juniper berries and other plant material. The minimum alcohol content in gin is 37.5% ABV (alcohol by volume). The aim of this study was to determine and compare the volatile compound profile of four different gin samples. The volatile compounds were isolated by headspace-solid phase microextraction (HS-SPME), using two fibers of different polarity, and identified by gas chromatography-mass spectrometry (GC- MS) technique. A total of 37 volatile compounds from the group of terpenes, terpenoids, esters and phenylpropanes were identified. 14 compounds were found in all samples, of which 13 had previously been identified in the essential oil of juniper berries (Juniperus communis). Ethyl acetate identified in all samples is commonly found in distilled spirits as a product formed during alcoholic fermentation by esterification of ethanol and acetic acid. Differences in the aromatic profiles of the samples are due to different recipes and production processes.
