Abstract

Abstract: In this research, cinnamon essential oil (CEO) loaded Pickering emulsion was incorporated into chitosan (CS)/gelatin (GEL) complex films. These antimicrobial functionalizations of biobased packaging films containing different contents (5, 7.5, and 10 mL) of CEO-loaded Pickering emulsion were evaluated on the microstructure, physicochemical, mechanical, barrier and antimicrobial properties. CEO-loaded Pickering emulsion was herein prepared with zein nanoparticles as a stabilizer showed an average size of 113.37 nm and exhibited excellent physical stability. Fourier transform infrared spectroscopy (FTIR) and wide-angle X-ray scattering (WAXS) analyses revealed that the CEO-loaded Pickering emulsion showed compatibility with CS/GEL matrix. Not only mechanical properties but also barrier properties of the prepared films were significantly improved ( P < 0.05 ) by incorporating CEO-loaded Pickering emulsion. Furthermore, incorporating CEO-loaded Pickering emulsion with CS/GEL led to the formation of high antimicrobial against Pseudomonad paralactis MN10 and Lactobacillus sakei VMR17 with slow-release behavior of CEO. These results suggested that Pickering emulsion is a promising antimicrobial agent delivery system for biopolymer based active packaging, notably for the conception of novel active packaging biobased polymers.

Mechanical and barrier properties of prepared films were enhanced. The antimicrobial activities and control release behavior of films were shown.
