ZnO nanoparticles stabilized oregano essential oil Pickering emulsion for functional cellulose nanofibrils packaging films with antimicrobial and antioxidant activity.
Int J Biol Macromol. 2021 Nov 01; 190:433-440.IJ

Abstract

The growth and reproduction of microorganisms can cause food spoilage in the process of food transportation and storage. Active packaging is a good way to inhibit food spoilage and prolong the shelf lives of foods. In this study, O/W Pickering emulsion with ZnO nanoparticles as solid particles and oregano essential oil as the oil phase was prepared and used to functionalize cellulose nanofibrils (CNFs) film, and excellent antimicrobial and antioxidant activity was obtained. When the concentration of ZnO nanoparticles was 1.5 wt% and the mass fraction of the oil phase was 20%, the Pickering emulsion with a particle size of 26.85 μm exhibited strong standing stability. The Pickering emulsion was blended with the film-forming matrix CNFs to prepare active packaging films by casting. The Pickering emulsion evenly dispersed in the film to form microcapsules which encapsulated oregano essential oil entirely. The antimicrobial activity against Listeria monocytogenes was 89.61%, the DPPH radical scavenging rate was 58.52%, while the barrier properties of the developed films against oxygen, water vapor and visible light were improved. The active CNFs film prepared by Pickering emulsion could inhibit the growth of microorganism and prolong the shelf lives of foods.
