“…Samples packed with the BS/ZnO-N 3% film exhibited a reduction of 0.86 log CFU g À1 after 6 days of storage, whereas other packaging exhibited no inhibitory activity against L. monocytogenes. Similarly, Khalaf et al (2013) reported that pullulan edible films incorporated with ZnO-N had antimicrobial activities against L. monocytogenes in turkey deli meat during storage.…”

Summary Buckwheat starch (BS) films containing zinc oxide nanoparticles (ZnO‐N; 0%, 1.5%, 3% and 4.5%) were prepared, and their physical, optical and antimicrobial properties were examined. As ZnO‐N content increased from 0% to 4.5%, TS increased from 14.99 to 19.09 MPa and E decreased from 25.60% to 20.65%. In addition, L* and a* values decreased, whereas b*, ΔE and opacity increased. Regarding antimicrobial activity, the BS/ZnO‐N films had the reductions of 2.96–3.74 log CFU mL−1 against Listeria monocytogenes after 8 h based on viable cell count assay. The BS film containing 3% ZnO‐N, an optimal concentration chosen in this study, was applied to fresh‐cut mushroom packaging, and the film exhibited antimicrobial activity against L. monocytogenes, resulting in a reduction of 0.86 log CFU g−1 after 6 days of storage. Thus, these results indicate that the BS/ZnO‐N film can be used as a biodegradable packaging material.

“…Furthermore, storage temperature of nanocomposite materials plays an important role since it can limit their antimicrobial stability. Khalaf et al [30] investigated the inhibitory potency of pullulan-based films containing silver nanoparticles against S. aureus and L. monocytogenes during 7 weeks of storage at different temperatures: 4, 25, 37, and 55 • C. The authors concluded that in order to maintain sustained bactericidal activity, nanomaterials should be stored at temperatures below 25 • C, as temperatures higher than 25 • C significantly reduced their antimicrobial potency. Table 1 summarized the antimicrobial activity of various biopolymer-based materials containing AgNPs through different preparation methods routes, as well as the size and concentration of AgNPs used.…”

Packaging is an integral part of food products, allowing the preservation of their quality. It plays an important role, protecting the packed product from external conditions, maintaining food quality, and improving properties of the packaged food during storage. Nevertheless, commonly used packaging based on synthetic non-biodegradable polymers causes serious environmental pollution. Consequently, numerous recent studies have focused on the development of biodegradable packaging materials based on biopolymers. In addition, biopolymers may be classified as active packaging materials, since they have the ability to carry different active substances. This review presents the latest updates on the use of silver nanoparticles in packaging materials based on biopolymers. Silver nanoparticles have become an interesting component of biodegradable biopolymers, mainly due to their antimicrobial properties that allow the development of active food packaging materials to prolong the shelf life of food products. Furthermore, incorporation of silver nanoparticles into biopolymers may lead to the development of materials with improved physical-mechanical properties.

Nanotechnology is an innovative technology for improving food quality and safety. Aims: The aim of this study was to evaluate the efficacy of hydroxy propyl methyl cellulose (HPMC) films containing nanoparticles against three foodborne pathogens. Design of the Study: *This study was designed using two nanoparticles i.e. (Al2O3-NPs and SiO2-NPs), edible film (HPMC), and three foodborne pathogens i.e. Bacillus cereus, Staphylococcus aureus, and Salmonella Typhimurium. Both nanoparticles were evaluated against foodborne pathogens as well applied in chicken fillets. Place and Duration: All experiments were done in the Food Technology Department, Benha University, Egypt; Nanomaterial Laboratory, Beni-Suef University, Egypt; and Agricultural Research Center, Egypt and were done within three months. Methodology: The preparation of edible films, the antimicrobial activity, mode of antimicrobial action, challenge study, and scanning electron microscopy had been carried out in different laboratories. As well the mechanical properties of the HPMC films were evaluated. Results: The results obtained from this study showed that the nanoparticles (~80 nm) at 80 ppm were active against Bacillus cereus, Staphylococcus aureus, and Salmonella Typhimurium compared with 20 and 40 ppm. The HPMC films including Al2O3-NPs were active against B. cereus than S. aureus and S. typhimurium, while the SiO2-NPs were more effective against S. typhimurium and B. cereus compared with S. aureus. In challenge studies, HPMC films including Al2O3-NPs and SiO2-NPs at 80 ppm decreased the viability of the three-foodborne pathogens associated with chicken fillets stored at 4±1°C for 15 days, as compared with the control sample. HPMC films incorporated with nanoparticles inhibited the microbial population ~ 2-3 log10 CFU/cm2 over the chicken fillets during storage period. Conclusion: This work indicated that, HPMC films incorporated with Al2O3-NPs and SiO2-NPs (~80 nm) at 80 ppm could be reduce the microbiological loads of the refrigerated chicken fillets.
