Sažetak
Herbal brandy Travarica is a strong alcoholic beverage which is traditionally produced in southern parts of Croatia. Herbal brandies are special brandies, flavored with plant extracts. Grape brandies, various macerates, percolates, infusions and other forms of herbal extracts are most often used for the production of herbal brandies. Biologically active compounds of medicinal and aromatic herbs are essential oils, flavonoids, tannins, saponins, slippery secretion and bitter matters which are extracted into alcoholic base on ambient temperature. Komovica brandy is mostly used as an alcoholic base. The goal of this work was to compare aromatic profile od four different herbal brandy specimens. The volatile compounds were isolated by headspace solid-phase microextraction (HS-SPME) and analyzed by gas chromatography-mass spectrometry (GC-MS). When comparing the obtained results, a different aromatic profile of specimens was found. Dominant compound identified in all the specimens is ethyl decanoate. The sample of brandy, produced by "Vinoplod" showed a more complex composition in relation to other tested samples.
