Abstract

The physicochemical and antimicrobial properties of kefiran-waterborne polyurethane blend film incorporated with Rosmarinus officinalis essential oil with concentrations of 2, 4, 6, 8 and 10 %v/v were investigated. By increasing the concentration of the essential oil, the scanning electron microscopy images showed inhomogeneous and pores in the films structures, while thickness of the resulting films did not show a significant difference (p > 0. 05), but significant decrease and increase were obtained for tensile strength and elongation at break, respectively (p < 0. 05). The water vapor permeability of films was increased up to 6% of essential oil but with further increase, it was significantly decreased (p < 0. 05). The results of inhibition zone test showed that the antimicrobial inhibitory properties of Rosmarinus officinalis essential oil against Staphylococcus aureus were greater than Escherichia coli. Decrease of 2, 1. 7 and 1. 85 logarithmic units was respectively observed in total count of microorganisms, E. coli and S. aureus on Ostrich meat during 12 days of storage in the refrigerator. The produced antimicrobial film has the potential to be applied in the packaging of different food.
