Development and Structural Characterization of PullulanLecithinZein Composite Nanofibers Loaded with Mountain Germander (Teucrium montanum) Polyphenolic Extract

In this study, the electrospinning technique was employed to encapsulate mountain ger- mander (MG) polyphenolic extract into pullulan/zein (PUL:ZE) delivery systems stabilized with sunflower lecithin. The rheological and physical properties of the pullulan (PUL), PUL:ZE, and zein (ZE) polymer solutions were evaluated to assess their electrospinnability potential. Fabricated nanofibers were then characterized for their morphology, physico- chemical, and thermal properties, as well as...
