| Abstract | ||
| In order to improve the physical and mechanical properties,reduce permeability to water vapor, antimicrobial properties and increase hydrophobicity, Salvia officinalis essential oils was combined with the chitosan-tragacanth-clay film. The combination of nanocomposite with three levels of S. officinalis essential oil (1, 1.5 and 2%) in order to choose the best coverage for using in the maintenance of rainbow trout were studied. The best properties of film (Mechanical and antibacterial properties and water absorption)were showed in1.5 % S. officinalis essential oil in combination with nanocomposite. Samples coated with this bionanocomposite, showed the lowest amount of total bacterial loadand phsycrotrophic bacteria when compared to the control during 16 days storage period (p<0.05). According to the results, the combination of chitosan-tragacanth-clay withS.officinalisessential oil, can improve the physical and mechanical properties of chitosan in the film, moreover it can improve its ability to seafood preservation like trout. | ||
