Opis (eng)

Pomegranate peel (P) proved a broad range of biological activities and health-promoting effects. Considering the great therapeutic potential of a P extract, this study aims to establish an encapsulation process, using biocompatible carriers to obtain preserved encapsulates with highly potent bioactive components. Microencapsulation method was performed by freeze drying technique. The content of total phenols, flavonoids, flavonols, flavan-3-ols and total and monomeric anthocyanins were determined spectrophotometrically in pure freeze-dried extract PPE (FPE), and its encapsulates, with whey protein (FPE+WP), maltodextrin (FPE+MD) and polydextrose (FPE+PD). Among encapsulates, the FPE+WP showed the highest content of all investigated components, except FPE+PD which demonstrated the highest flavonoids content. FPE+WP showed the highest antioxidant activity by DPPH (IC50=13.81μg/ml), while FPE+MD by ABTS (IC50=3.15 μg/ml) and OH (IC50=18.88 μg/ml) tests. Samples exhibited high antimicrobial potential. All obtained wild pomegranate peel encapsulates proved good multifunctional properties with potential as food and pharmaceuticals.
