Abstract
Voćne rakije spadaju u jaka alkoholna piće dobivena alkoholnom fermentacijom i destilacijom etilnog alkohola prirodnog podrijetla iz plodova voćki. Minimalni udio alkohola u voćnim rakijama je 37,5 % vol. Cilj ovog istraživanja bio je ustanoviti i usporediti profil hlapljivih spojeva tri različita uzorka voćne rakije. Hlapljivi spojevi izolirani su mikroekstrakcijom vršnih para na krutoj fazi (HS-SPME), koristeći svijetlo plavo i sivo vlakno i identificirani uz pomoć vezanog sustava plinska kromatografija- spektrometrija masa (GC-MS). Identificirano je ukupno 25 hlapljivih spojeva od kojih je 14 estera, 4 aldehida, 4 viša alkohola, 2 monoterpena, 1 seskviterpen. Najzastupljeniji hlapljivi spojevi su viši alkoholi 3-metilbutan-1-ol te etilni esteri etil-dekanoat i etil-oktanoat. Uočene su razlike u aromatskim profilima uzoraka ovisno o različitim recepturama i proizvodnim procesima.
Abstract (english)
Fruit brandies belong to strong alcoholic beverages obtained by alcoholic fermentation and distillation of ethyl alcohol of natural origin from the fruits of fruit trees. The minimum alcohol content in fruit brandy is 37,5% vol. The aim of this research was to establish and compare the profile of volatile compounds of three different samples of fruit brandy. Volatile compounds were isolated by headspace solid phase microextraction (HS-SPME), using a light blue and gray fiber and were identified by a hyphenated system gas chromatography-mass spectrometry (GC-MS). A total of 25 volatile compounds were identified, of which 14 were esters, 4 aldehydes, 4 higher alcohols, 2 monoterpenes, 1 sesquiterpene. The most common volatile compounds are higher alcohols 3-methylbutan-1-ol and ethyl esters ethyl decanoate and ethyl octanoate. Differences in the aromatic profiles of the samples were observed depending on different recipes and production processes.
