Abstract
U radu je istražena primjena 2D-korelacijske spektroskopije za detekciju umjetnih bojila u voćnim sokovima crnog ribiza. Spektrofotometrijski su snimani uzorci soka, bojila i soka sa dodatkom bojila u području pH vrijednosti od 3,5 do 5,0 s rezolucijom od 1 nm u području valnih duljina od 400 do 700 nm. Dobiveni spektri su filtrirani Savitzky-Golayevom metodom, derivirani i korišteni za izradu sinkronih i asinkronih korelacijskih mapa. Usporedbom dobivenih korelacijskih mapa u području valnih duljina većih od 530 nm mogu se jasno detektirati spektalne promjene uzrokovane dodatkom umjetnog bojila u sok.
Abstract (english)
This work explores the application of 2D-correlation spectroscopy for the detection of color additives in fruit juices of black currant. The samples of juice, azo-dyes and juice with azo-dyeswere spectroscopically examined in the pH range from 3.5 to 5.0, with a resolution of 1 nm in the wavelength range from 400 to 700 nm. Collected spectra were smoothed by the Savitzky-Golay method, numerically derived and employed for calculation of synchronous and asynchronous correlation maps. Spectral changes caused by the addition of azo-dyes to the juice can be clearly detected by comparing the obtained correlation maps in the wavelength range greater than 530 nm.
