Abstract:
ε-Polylysine (PL), as a promising antibacterial agent, is witnessing increasing interest concerning its improved pragmatic performance. This work aims to investigate the interactions between PL and glutenin to produce complex coacervates, thus creating functional edible coatings for strawberry preservation. When the mass ratio (glutenin: PL) reached 5, stable complex coacervation was established with a network-like and porous microstructure. Electrostatic interactions and hydrogen bonding were predominant in the interactions between PL and glutenin by molecular docking and molecular dynamics. Furthermore, the efficient antibacterial effects of complex coacervation were demonstrated through the results of the inhibition zone and bactericidal kinetics. Edible coating derived from complex coacervation reduced the water vapor permeability by 17.24 % and the oxygen permeability coefficient by 7.92 %. Strawberry preservation experiments confirmed that the complex coacervation coating could effectively lengthen the shelf-life. This study offers a novel path for the development of edible coating in fruit preservation.
