Abstract
Cilj ovog istraživanja je potenciometrijski odrediti sadržaj fluoridnih iona u bijelim vinima sorte pošip s različitih geografskih područja te usporediti i objasniti moguće razlike u koncentracijama fluorida za različite lokacije i sorte vina. Fluoridi u vinu su određeni metodom standardnog dodatka upotrebom fluorid-ionsko selektivne elektrode. Ispitana je koncentracija fluorida u 12 uzoraka vina sa otoka Pelješca, Korčule, Hvara i iz Konavla. Vinarija s najvećom koncentracijom fluorida (447,4 ± 48,98 µg L -1 ) je smještena na otoku Korčuli, a s najmanjom (264,8 ± 11,47 µg L -1 ) koncentracijom fluorida smještena je u središnjem dijelu otoka Pelješca. Uzrok različitih koncentracija može biti: geografsko područje, upotreba pesticida i umjetnih gnojiva te tehnološki procesi proizvodnje vina. Koncentracije fluorida uzoraka vina iz središnjeg dijela otoka Pelješca su vrlo slične. Uzorci vina proizvedenih u istoj vinariji na Hvaru značajno se razlikuju zbog upotrebe dvije različite sorte vinove loze (pošip vs. pošip selekcija).
Abstract (english)
The aim of this research is to potentiometrically determine the content of fluoride ions in white wines of the Pošip variety from different geographical areas, and to compare and explain possible differences in fluoride concentrations for different locations and wine varieties. Fluorides in wine were determined by the standard addition method using a fluoride-ion selective electrode. The concentration of fluoride in 12 wine samples from the islands of Pelješac, Korčula, Hvar and Konavle was tested. The winery with the highest fluoride concentration (447.4 ± 48.98 µg L -1 ) is located on the Korčula Island, and the winery with the lowest (264.8 ± 11.47 µg L -1 ) fluoride concentration is located in the central part of the Pelješac Island. The cause of different concentrations can be: geographical area, use of pesticides and artificial fertilizers, and technological processes of wine production. Fluoride concentrations of wine samples from the central part of the island of Pelješac are very similar. Samples of wines produced in the same winery on Hvar show significant differences due to the use of two different grape varieties (Pošip vs. Pošip Selection).
