Abstract
Novi trendovi na području sigurnosti hrane povećali su fokus na elemente i spojeve u tragovima koji mogu utjecati na ljudsko zdravlje, u koje se ubrajaju i biogeni amini. Biogeni amini su biološki aktivni dušični spojevi male molekulske mase. U vinu mogu nastati iz prekursora, djelovanjem mikroorganizama u bilo kojoj fazi proizvodnje. Cilj ovoga rada bio je ispitati utjecaj vremena odležavanja na kvascima na sadržaj biogenih amina u pjenušcu kultivara Syrah. Kvantitativno određivanje biogenih amina provedeno je pomoću RP-HPLC (Reversed Phase High Performance Liquid Chromatography), te je utvrđeno da je vrijeme odležavanja na kvascima ima značajan utjecaj na sadržaj biogenih amina u pjenušcu kultivara Syrah. Uzorci s kraćim vremenom odležavanja na kvascima sadržavali su niži udio biogenih amina (5,41 mgL-1 u odnosu na 7,24 mgL-1)
Abstract (english)
New trends in food safety have increased the focus on trace elements and compounds that can affect human health, including biogenic amines. Biogenic amines are biologically active, low molecular weight nitrogen compounds. In wine, they can arise from precursors by the action of microorganisms at any stage of production. The aim of this study was to investigate the influence of yeast aging time on the biogenic amine content of Syrah sparkling wine. Quantification was performed using RP-HPLC (Reversed Phase High Performance Liquid Chromatography) and it was found that yeast aging time significantly influence on biogenic amine content in Syrah cultivars sparkling wine. Samples with shorter yeast aging time contained a lower proportion of biogenic amines (5.41 mgL-1 versus 7.24 mgL-1)
