Abstract :
The active films composed of polyvinyl alcohol/Alyssum homolocarpum seeds gum (PVA-AHSG) in corporating lysozyme (LY) are developed and characterized. The LY affects the thickness, solubility, and water vapor permeability, mechanical, microstructural, and optical properties of PVA-AHSG films and also the antimicrobial activities of obtained films are evaluated. The LY content increased the thickness of composite films. The LY addition led to an increase in water solubility, moisture contents, and contact angle, and decreased density. The control films without LY had the lower opacity and acted as a weak barrier against the water vapor. The LY reduced elongation at break and slightly increased tensile strength and elastic modulus. The electron micrographs showed that the control films had a smoother structure, and the addition of LY formed films with a rough surface. Fourier Transform-Infrared Spectra indicated some interactions between PVA and AHSG chains and LY. Functional activities were found against Gram-positive Listeria monocytogenes and Staphylococcus aureus.
