Production and Characterization of Antimicrobial Carboxymethyl Cellulose (CMC) Films Containing Essentiol Oils of Satureja khuzistanica, Zataria multiflora, Allium sativum and Bunium persicum

The aim of this study was to evaluate antimicrobial effects of Zataria multiflora Boiss. Satureja khuzistanica Jamzad, Bunium persicum (Boiss.) B. Fedtsch. and Allium sativum L. essential oils and the use of the most effective one in packaging and evaluation of the film properties. The antimicrobial activity against P. aeruginosa, S. aureus, E.coli, B. cereus, S. enteritidis was studied using the disk diffusion method and MIC and MBC was determined. Then CMC films produced with the addition of Zataria multiflora Boiss. And Satureja khuzistanica essential oils (۱.۶%, ۲.۴%, and ۳.۲%). The addition of essential oils caused to reduce the moisture content to ۱۶.۲۵% and ۱۷.۹۱%, solubility to ۶۹.۰۱% and ۶۴.۷۸%, the color difference to ۲۱.۵۰ and ۱۲.۸۶ and tensile strength to ۵۴.۱۲ and ۲۹.۲۶ ­Mpa, respectively. An increase in concentration of Satureja khuzistanica essential oil made the film more resistant to water diffusion by ۱.۰۵×۱۰-۱۳(g/s m Pa) compared to Zataria multiflora. Regarding the possibility of producing the degradable film with antimicrobial essential oils, it is desirable to use these materials to increase food shelf life.
