Effect of selected bioactive substances and nanoparticles on the immunoreactivity of edible packages containing chitosan, by the ELISA method

The aim of this study was evaluated the effect selected bioactive substances and nanoparticles on immunoreactivity edible packages based chitosan using ELISA. analysed protein tropomyosin. results confirmed presence tropomyosin (3.77 ± 0.79–5.75 0.01 µg/g) in control samples. This demonstrated that form grape (0.61 0.34–0.43 0.16 µg/g), blueberry (0.58 0.32–0.39 0.27 parsley extracts (2.09 1.28–0.79 0.40 reduces (p < 0.05) elder pollen had no significant > immunoreactivity. ZnO TiO2 also reduction 0.05). exception silver nanoparticles, where increased with increasing concentration extract (1.29 0.01–5.47 0.25 µg/g). inhibitory used ELISA showed need to consider immunoreactive when interpreting results.
