Abstract
Pripadnici životinjskog carstva malih dimenzija, iznimno važni za ljudski život na Zemlji, su pčele. Medonosne pčele u Bosni i Hercegovini i Republici Hrvatskoj su Apis mellifica, Apis cerana i Apis mellifera. Pčelinji proizvodi su med, pčelinji otrov, polen, matična mliječ, vosak. Senzorska svojstva meda čine boja, okus i miris. Hlapljivi spojevi su nositelji mirisa prehrambenih proizvoda, pa tako i meda. Kako je miris jedna od komponenti arome, hlapljivi spojevi se često nazivaju i „spojevima arome“. U ovom radu hlapljivi spojeva meda iz vlastitog obiteljskog poljoprivrednog gospodarstva OPG-a Trupina (Bosna i Hercegovina) izolirani su ultrazvučnom ekstrakcijom (USE), ekstrakcijom tekuće-tekuće (LLE) i mikroekstrakcijom vršnih para na krutoj fazi (HS-SPME). Dobiveni ekstrakti su analizirani plinskom kromatografijom-masenom spektrometrijom. Glavni sastojci u ultrazvučnim ekstraktima su ravnolančani ugljikovodici dokosan (C 22 H 46 ) i trikosan (C 23 H 48 ). Monoterpenski eter (Z)-anetol je glavni spoj u vršnim parama meda iz 2019. god., a glavni sastojci vršnih para meda iz 2018. god. su benzaldehid i cis-linalol oksid. Ekstrakcijom tekuće-tekuće izoliran je mali broj spojeva, a i uspješnost identifikacije nije zadovoljavajuća te metoda nije prikladna za izolaciju hlapljivih spojeva iz meda.
Abstract (english)
Important members of animal kingdom living on the Earth which contribute to the better quality of human life are bees. Honey bees in Bosnia and Herzegovina and Republic of Croatia are Apis mellifera, Apis cerana and Apis mellifica. Product of bee keeping are venom, pollen, royal jelly, wax and honey. The honey sensory properties are color, taste and aroma. The volatile compounds are the main aroma compounds of foods andhoney, too. The methods used for the extraction of volatile compounds of meadow honey originating from family apiary Trupina (Bosnia and Herzegovina) are ultrasonic extration (USE), liquid-liquid extraction (LLE) and headspace solid-phase microextraction (HS-SPME). Analysis of all samples was carried out by gas chromatography-mass spectrometry (GC/MS). The main compounds in USE extracts are straight chain hydrocarbons docosane (C 22 H 46 ) and tricosane (C 23 H 48 ). Monoterpene ether (Z)-anethol is the major constituent of honey headspace, sample from 2019. The main constituents of honey headspace, sample from 2018., are benzaldehyde and cis-linalool oxide. Small number of compounds is isolated by liquid-liquid extraction and extraction efficiency wasn't satisfactory, too. So, liquid-liquid extraction is not appropriate method for the isolation of honey volatiles.
