Fabrication and application of functional active packaging material based on carbohydrate biopolymers formulated with Lemon verbena/Ferulago angulata extracts for the preservation of raw chicken meat

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 mu l 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 mu l LVE and FAE film. In conclusion, the 20:80 proportion of ZG/CMC along with 2.5 mu l 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.
