AB  - This study aimed to develop active, biodegradable materials for food packaging by incorporating sage extract (SE) within a zein-gelatin blend by electrospinning and solvent casting. The fabrication techniques, SE incorporation, and its content (5, 10% w/w) determined the materials’ properties. Electrospinning produced 0.36–0.53 mm thick, non-transparent fibrous mats (mean fiber diameter 1.12–1.36 µm). Solvent casting generated 0.34–0.41 mm thick, transparent continuous films. The analysis indicated the constituents’ compatibility, homogenous dispersion, and efficient SE incorporation without strong chemical interactions and phase separation. The solvent-cast films presented more ordered structures, higher mechanical resistance, elongation, and water vapor barrier performance than the electrospun mats. The SE-incorporating formulations showed phenolics’ delivery ability to food simulants influenced by structure, SE content, and media polarity. The electrospun mats expressed higher DPPH• radicals’ inhibition, while the solvent-cast films showed stronger Staphylococcus aureus and Escherichia coli growth inhibition, increased by SE incorporation. All formulations showed rapid complete bio-disintegration in compost (18–25 days). © 2023 Elsevier Ltd

AB  - In this study conditions for green crosslinking with citric acid of chitosan/PEO (polyethylene oxide) nanofibers were evaluated. The thermal in situ crosslinking enabled penetration of crosslinking agent into the matrix providing an improvement of antibacterial activity, thermal stability and mechanical properties of the prepared material. With an increase of temperature above 80 degrees C antibacterial activity against Staphylococcus aureus and Escherichia coil, inversely decreased. Moreover crosslinking provided prolonged controlled drug release with outstanding increase of mechanical properties observed by nanoindentation measurements. Results of the investigation indicated crosslinking as an important parameter for producing material with multifunctional characteristics suitable for drug delivery and tissue engineering.
