Sažetak
Wild plants have recently attracted attention due to the rich content of bioactive components and the potential positive effect on human health [1]. Among them, elderflower is recognizable for its intense and attractive flavor but also due to its rich phenolic acids and flavonoid content. [1]. Dietary fibers, besides health benefits, have the ability to interact with polyphenols. The aim of the present study was to prepare bioactive complexes based on apple or citrus fibers with elderflower polyphenols. Elderflower extract (water:ethanol 1:1) was mixed with 4% of apple or citrus fibers and then freeze-dried. Obtained powders were evaluated spectrophotometrically for total polyphenols content and antioxidant activity (FRAP, CUPRAC, ABTS and DPPH assays) as well as for individual polyphenols content by HPLC analysis. IR spectra were recorded to confirm complexation. Obtained results showed that bioactive complex with apple fibers possessed higher total polyphenols content (5.41 g/kg) than complex with citrus fibers (3.48 g/kg). Chlorogenic acid and rutin are polyphenols usually present in elderflower extracts and also identified and quantified in these complexes. The results of antioxidant activity followed the same trend as for total polyphenol content. These bioactive complexes can be applied for the enrichment of different food products with antioxidants.
