The main aim of this study was to characterize the physical, optical and antimicrobial properties of chitosan-gelatin blend films enriched with cinnamon, nutmeg and thyme essential oils. Microstructure determined by scanning electron microscopy showed that active films had heterogeneous surface. The presence of new bands and changes in the FTIR spectra confirmed intermolecular interactions between the chitosan-gelatin matrix and essential oils. The active films proved as effective barriers against UV light and inhibited the growth of four major food bacterial pathogens, showing potential as environmentally friendly antimicrobial packaging material.

Abstract
The main aim of this study was to characterize the physical, optical and antimicrobial properties of chitosan-gelatin blend films enriched with cinnamon, nutmeg and thyme essential oils. Microstructure determined by scanning electron microscopy showed that active films had heterogeneous surface. The presence of new bands and changes in the FTIR spectra confirmed intermolecular interactions between the chitosan-gelatin matrix and essential oils. The active films proved as effective barriers against UV light and inhibited the growth of four major food bacterial pathogens, showing potential as environmentally friendly antimicrobial packaging material.
