In this research using 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 were made by applying the casting process. The 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 the best ratio for mechanical properties, moisture content, and permeability compared to the CMC/ZG film with individual FAE or LVE and can be a good source for making edible films.
Novelty impact statement
- The most important novelty is related to using of Lemon verbena and Ferulago angulata extracts in the combination of Zedo gum and carboxymethyl cellulose.
- Producing active packaging with Lemon verbena and Ferulago angulata extracts in polymer matric.
- Increasing the shelf life of compounds such as raw chicken meat with active packaging.
