【 摘 要 】

Antimicrobial food packaging was developed in response to the growing demand forlonger fresh food shelf life and protection against foodborne infections. Therefore,the current study was conducted to investigate the antimicrobial effect of homemadebiodegradable antimicrobial films incorporated with silver nanoparticles (Ag-NPs)against Staphylococcus aureus (S. aureus) experimentally inoculated in chickenbreast. Chicken breast slices (5 × 5 cm) were experimentally inoculated with a cocktailof three S. aureus strains at a concentration of about 6.6 log10 CFU/cm2 and wrappedin homemade biodegradable antimicrobial films. Following that, the residual bacterialcounts in wrapped chicken breast fillet slices were monitored for up to 10 days in arefrigerator (4 °C). It was found that at the end of the chilling period the films withbiosynthesized Ag-NPs(1mM), biosynthesized Ag-NPs(2mM), chemically synthesizedAg-NPs (1mM), and chemically synthesized Ag-NPs (2mM) reduce the S. aureuscounts by about 4.66, 5.24, 4.79, and 5.43 log10 CFU/cm2, respectively whencompared with control films. Biodegradable antimicrobial films also prolonged theshelf-life of samples by approximately 4 days when compared to control samples.
