Abstract

Abstract The evaluation of the physicochemical and antimicrobial properties of kefiran/waterborne polyurethane blend (K/WPU) film incorporated with Zataria multiflora (ZM) and Rosmarinus officinalis essential oils (RO) with concentration 5, 10, 15 and 20% (v/v) for ostrich meat packaging were the goals of this study. The band shift of the Fourier transform infrared spectra implied that intermolecular hydrogen bonding between the EOs and K/WPU film. By increasing the EOs concentration on the films thickness, elongation at break and yellowness index were increased while water vapor permeability, tensile strength, lightness and whiteness index significantly decreased (P
