Abstract

Aroma vina rezultat je interakcija između kemijskog sastava vina sa osjećajem okusa i mirisa kod konzumenata vina. Glavni predstavnici primarne arome koji utječu na karakter i senzorske karakteristike vina su terpeni, C13-norizoprenoidi i C6-alkoholi. Uzorci mošta bijele sorte grožđa Pošip analizirani su metodom plinske kromatografije s masenom spektrometrijom uz mikroekstrakciju na čvrstoj fazi (SPME-GC/MS). Identificirano je 11 različitih spojeva, a primarnoj aromi 6 analiziranih uzoraka mošta najviše doprinose β-ionon (mirisa meda, ruže, ljiljana) i β-damaskenon koji je nositelj cvjetne arome te C6-spojevi su nosioci vegetativne arome te geraniol koji je nositelj slatke arome.

Abstract (english)

The aroma of wine is the result of interactions between the chemical composition of wine with a sense of taste and smell in the wine consumers. Main compounds of primary aroma that affect the character and sensory guality of wines are terpenes, C13-norisoprenoids and C6-alcohols. Must samples of white grape variety Pošip were analyzed using solid-phase microextraction method followed by gas chromatography-mass spectrometry (SPME-GC/MS). 11 diferent compounds were determined, the biggest contribution to the primary aroma from 6 analyzed must samples were β-ionone (honey, spice, rose, lilac aroma) and β-damascenone (almond, sweet aroma) also C6 compounds with vegetative aroma and geraniol with sweet aroma.
