Abstract
U ovom završnom radu odreĊivane su koncentracije umjetnog bojila (quinoline yellow) u raznim prehrambenim proizvodima spektrofotometrijskom UV/VIS metodom. Spektrofotometrijsko mjerenje je provedeno u destiliranoj vodi pri pH vrijednosti 7. OdreĊivanje koncentracije QY provodilo se sa dvije metode (pomoću krivulje umjeravanje i metodom standardnog dodatka) u 2 tipa uzoraka (pićima, bombonima, tabletama). Usporedbom ovih dviju metoda vidimo da su veoma male razlike u dobivenim rezultatima, a što se uzoraka tiĉe najveće koncentracije su pronaĊene u Cedeviti grejp (81,374 mg/L) i Lizi (169,606mg/L).
Abstract (english)
In this final work, quinoline yellow concentrations were determined in various food products by spectrophotometric UV / VIS method. Spectrophotometric measurement was carried out in distilled water at pH 7. Determination of QY concentration was performed using two methods (using the calibration curve and the standard addition method) in 2 types of samples (beverages, candies, tablets). Comparison of these two methods shows that very little differences in the results obtained, and the highest concentration of the samples, were found in cedeviti Grapefruit (81.374 mg / L) and Lysis (169.606 mg / L).
