Abstract
U ovom završnom radu izvršena je analiza sastava i sadržaja hlapljivih spojeva kozjeg sira iz mišine. Izolacija hlapljivih spojeva provedena je mikroekstrakcijom vršnih para na krutoj fazi korištenjem dva vlakna različitog sastava (svjetlo-plavo i sivo) pri tri različite temperature (40, 50 i 60°C). Dobiveno je ukupno šest uzoraka koji su analizirani vezanim sustavom plinska kromatografija-spektrometrija masa na HP-5MS koloni. U svim uzorcima, bez obzira na vrstu vlakna, pronađene su sljedeće klase spojeva: karboksilne kiseline, esteri, ketoni i alkoholi, s tim da su karboksilne kiseline bile najzastupljenije u svim uzorcima. Različite temperature ekstrakcije nisu značajnije utjecale na kemijski sastav i sadržaj hlapljivih spojeva.
Abstract (english)
In this bachelor thesis, the composition and content of volatile compounds from the goat cheese in a sack were analyzed. Isolation of volatile compounds was performed by solid phase microextraction (HS- SPME) using two fibers of different composition (light blue and gray) at three different temperatures (40, 50 and 60°C). A total of six samples were obtained and analyzed by a coupled gas chromatography-mass spectrometry system on an HP-5MS column. In all samples, regardless of the type of fiber, the following classes of compounds were found carboxylic acids, esters, ketones and alcohols, with carboxylic acids being the most abundant in all samples. Different extraction temperatures did not significantly affect the chemical composition and content of volatile compounds.
