Abstract
Cilj istraživanja bio je odrediti koncentraciju fluorida u pivima različitih vrsta potencijometrijski. Određena je koncentracija fluorida, volumni udio alkohola te pH u 30 uzoraka svijetlih i 19 uzoraka tamnih piva. Koncentracija fluorida sadržanog u analiziranim uzorcima piva određivana je metodom standardnog dodatka pri pH vrijednosti 5,5. Masene koncentracije fluorida u svim uzorcima piva su manje od 149,07 µg/L a veće od 53,02 µg/L. Najveća masena koncentracija fluorida zabilježena je kod piva 5th element Beer Lela 179,90 µg fluorida/L uzorka iz Daruvarske pivovare. Najmanja masena koncentracija fluorida zabilježena je kod Bura Brew Optimist 48,61 µg fluorida/L iz Bura Brew Poreč pivovare. Pivo je kiseli prehrambeni proizvod i pH se kretao u području od 3,23 do 4,79. Udio alkohola kod svijetlih piva u rasponu od 0% do 6%, a kod tamnih piva su u rasponu od 2% do 7,5%. Sve analizirane pive imaju dozvoljenu koncentraciju fluorida koja u Hrvatskoj iznosi 1,5 mg/L što se slaže i sa vrijednostima preporučenim od strane Svjetske zdravstvene organizacije ( WHO).
Abstract (english)
The aim of the study was to potentiometrically determine the concentration of fluoride in beers of different types. Fluoride concentration, alcoholic strength by volume and pH were determined in 30 samples of light and 19 samples of dark beers. The concentration of fluoride contained in the analyzed beer samples was determined by the method of standard addition at pH 5.5. Mass concentrations of fluoride in all beer samples are less than 149.07 µg / L and higher than 53.02 µg / L. The highest mass concentration of fluoride was recorded in the beer 5th element Beer Lela 179.90 µg fluoride / L sample from Daruvar Brewery. The lowest mass concentration of fluoride was recorded at Bura Brew Optimist 48.61 µg of fluoride / L from Bura Brew Poreč brewery. Beer is an acidic food product and the pH ranged from 3.23 to 4.79. The alcohol content of light beers ranges from 0% to 6%, and dark beers range from 2% to 7.5%. All analyzed beers have a permitted concentration of fluoride in Croatia of 1.5 mg / L, which agrees with the values recommended by the World Health Organization (WHO).
