Preparation of chitosan/zinc oxide/Melissa officinalis essential oil nano-composite film and evaluation of physical, mechanical and antimicrobial properties by response surface method

The use of biodegradable films for releasing antimicrobials into food packaging is an active packaging type in the food industry. In this study, an antibacterial film was produced based on the chitosan biopolymer, in which zinc oxide (ZnO) particles (0, 1 and 3% (W/V)) and Melissa essential oil (0, 0.25 and 0.5% (W/V)) were used for the enhancement of the biopolymer properties based on the central composite design (CCD).
