Abstract
U ovom radu ispitivala se je mogućnost pripreme bioaktivnoh dodataka hrani na bazi citrus vlakna/ksantana i fenola aronije. Dobiveni kompleksi su se međusobno razlikovali u količini dodanog vlakna dok je količina soka aronije bila konstantna. Na kompleksima su utvrđeni adsorbirani fenoli, proantocijanidini i antocijani. Također su određeni parametri boje i antioksidacijska aktivnost. Najveća adsorpcija ukupnih fenola, proantocijanidina i antocijana na kompleks citrus vlakna/ksantan je postignuta primjenom najmanje količine odnosno 1 % adsorbensa prilikom kompleksiranja. Ujedno je i navedeni kompleks imao najveću antioksidacijsku aktivnost. Kompleksiranja citrus vlakna/ksantan sa sokom aronije dolazi do promjene u strukturi kompleksa u odnosu na čista vlakna što je potvrđeno snimanjem IR spektra.
Abstract (english)
The aim of this study was to investigate possibility of preparation of bioactive food additives based on citrus fibre/xanthan and chokeberry phenolics. Obtained complexes differ in amount of used fibre while amount of chokeberry juice was constant. Complexes were evaluated for adsorption of phenolics, proanthocyanidins and anthocyanins. Also, colour parameters and antioxidant activity of the complexes were determined. The highest adsorption of phenols, proantocyanidins and anthocyanins on citrus fibre/xanthan was achieved when fibre was used in the lowest amount for complexation. The same complex had the highest antioxidant activity. Complexation of citrus fibre/xanthan with chokeberry juice caused change in complex structure in comparison to pure fibres what was proven by recording of IR spectra.
