Abstract
U ovom radu analiziran je kemijski sastav hlapljivih spojeva craft piva „Mrka“. Tijekom proizvodnje craft piva „Mrka“ dodani su začini poput metvice, cimeta, muškatnog oraščića i čokolade radi poboljšanja mirisa i okusa piva. Hlapljivi spojevi izolirani su dvjema različitim metodama: mikroekstrakcijom vršnih para na krutoj fazi (HS-SPME) s dva različita vlakna te kontinuiranom ekstrakcijom tekuće-tekuće s organskim otapalom te su analizirani spregnutom tehnikom plinska kromatografija–spektrometrija masa (GC-MS) u cilju usporedbe sličnosti i razlika dobivenih rezultata. SPME metodom identificirano je 37 različitih spojeva dok je kontinuiranom ekstrakcijom tekuće-tekuće identificirano njih 23. Identificirani spojevi mogu se svrstati u sljedeće kemijske skupine: alkoholi, esteri, alkaloidi, terpenski spojevi i ketoni.
Abstract (english)
In this paper, the chemical composition of volatile compounds of craft beer "Mrka" is analyzed. During the production of craft beer "Mrka", spices such as mint, cinnamon, nutmeg and chocolate were added to improve the smell and taste of beer. The volatile compounds were isolated by two different methods: solid phase peak extraction microextraction (HS-SPME) with two different fibers and continuous liquid- liquid extraction with an organic solvent, and were analyzed by the gas chromatography–mass spectrometry (GC-MS) conjugation technique for comparison. similarities and differences in the results obtained. 37 different compounds were identified by the SPME method, while 23 were identified by the continuous liquid-liquid extraction method. The identified compounds can be classified into the following chemical groups: alcohols, esters, alkaloids, terpene compounds and ketones.
