Abstract
U ovom radu određivao se utjecaj različitih koncentracija pululana na zadržavanje vanilina u hidrogel inkapsulatima. Pripremljeni su hidrogelovi s alginatom i dodatkom 0,5 %, 1 %, 1,5 % ili 2 % pululana. U pripremljenim uzorcima određen je udio pululana i antioksidacijska aktivnost. Udio vanilina određen je tekućinskom kromatografijom a za određivanje antioksidacijske aktivnosti korištene DPPH, ABTS, CUPRAC, FRAP i Folin-Ciocalteu metode. Najveći udio vanilina utvrđen je u hidrogel inkapsulatima s dodatkom 0,5 % pululana, a samim time taj uzorak ima i najveću antioksidacijsku aktivnost. Najmanji udio vanilina određen je u hidrogelu s 1,5 % pululana.
Abstract (english)
In this work, the influence of different concentrations of pullulan on the retention of vanillin in hydrogel encapsulates was determined. Hydrogels with alginate and 0.5%, 1%, 1.5% or 2% pullulan were prepared. The vanillin content and antioxidant activity of prepared samples were evaluated. The amount of vanillin was determined by liquid chromatography, while the DPPH, ABTS, CUPRAC, FRAP and Folin-Ciocalteu methods were used to determine the antioxidant activity. When obtaining the results, it was observed that the largest amount of vanillin was retained with the addition of 0.5% pullulan, and thus that showed the highest antioxidant activity. Also, the lowest amount of vanillin was determined in the hydrogel with 1,5% pullulan.
