Abstract
In this research by using of Zedo gum (ZG) and carboxymethyl cellulose (CMC) as well as Lemon and Ferulago extracts (LVE/FAE) new active packaging was designed. Biodegradable films with five various proportions of ZG to CMC was made applying casting process. Incorporation of LVE or FAE into CMC/ZG composite films significantly reduced moisture content (MC) and water vapor permeability (WVP). The tensile strength increased from 6.92 (MPa) for CMC/ZG film to 11.51 MPa for CMC/ZG/2.5 μL LVE and FAE film; as well as elongation at break decreased from 24.21% for CMC/ZG film to 6.10% for CMC/ZG/2.5 μL LVE and FAE film. In conclusion the 20:80 proportion of ZG/CMC along with 2.5 μL LVE and FAE can be used as a best ratio for mechanical properties, moisture content and permeability compare to the CMC/ZG film with individual FAE or LVE and can be a good source for making edible films.
