Production and analysis of blackberry fruit wine

Kupinovo vino bogato je kalijem i organskim željezom, pa je interesantno zbog svog učinka na zdravlje ljudi. Zbog malog udjela natrija ono pozitivno utječe na sniženje krvnog tlaka, stoga se preporuča za prehranu ljudi u umjerenim, ali svakodnevnim količinama. Određena je prisutnost devet metala u kupinovom voćnom vinu čakovečkog vinogorja, proizvedenog 2007. godine. Metoda ionske kromatografije (IC) korištena je za određivanje natrija, kalija, kalcija i magnezija. Brza i precizna metoda induktivno spregnute plazme optičko emisijske spektrometrije (ICP OES) korištena je za određivanje željeza, bakra, cinka, nikla i mangana. Kemijskim metodama i postupcima određeni su osnovni parametri kakvoće analiziranog vina: ukupne i hlapive kiseline, ukupni sumpor, šećer i alkohol. U analiziranom kupinovom voćnom vinu koncentracije prisutnih metala, kao i osnovnih sastojaka u vinu su u skladu s literaturnim podacima.Blackberry fruit wine is rich on potassium and organic iron, so it became interesting due to its good effects on human health. It also contains small amounts of sodium which can decrease high blood pressure. So, it is recommended in human nutrition in mediated, but daily amounts. In the blackberry wine from Čakovec wine region, produced in 2007, content of nine metals was determined. Ion chromatography (IC) was used for determination of sodium, potassium, calcium and magnesium. Quick and precise method of inductively coupled plasma atomic emission spectroscopy (ICP OES) was used to determine iron, copper, zinc, nickel and manganese. The chemical methods and procedures were used to determine the basic parameters of analyzed wine: total and evaporative acids, total sulfur, sugar and alcohol. In the analyzed blackberry fruit wine concentrations of determined metals as well as basic parameters corresponded well to the values in literature
