Ide nanoparticles (MgONPs) have also been explored to create nanocomposites for active meals packaging materials [51]. Within the study, the authors have synthesized nanocomposite films of MgONP and carboxymethyl chitosan. The incorporation of MgONP inside the chitosan-derivative matrix enhanced the thermal stability, UV-barrier property, and water insolubility, generating films suitable for water-rich meals items. The films showed excellent antimicrobial activity against L. monocytogenes and S. baltica [51]. Recently, silver nanoparticle-embedded nanocomposites, wherein a chitosan/PVA blend was applied as the polymer matrix, have been synthesized in [52]. The S 24795 Purity chitosan was employed as the stabilizing agent with the silver nanoparticles. The nanocomposite matrices ready by way of electrospinning showed antimicrobial activity against L. monocytogenes and E. coli. The films have been also evaluated for their potential to boost the shelf life of meat items. The study final results suggested that the composite films protracted the shelf life on the meat items by one particular week. In a further study, the silver-loaded nano-titania was then made use of because the filler material for the synthesis of fish gelatin and chitosan materials [53]. The interactions inside the nano-composite films had been improved by the silver-loaded nano-titania. The nano-composite films have been anticipated to perform properly as active packaging components. The use of natural polymer-based nanoparticles permits for the improvement of your properties in the chitosan films without having compromising the biodegradability of your films. This is since 6-trans-12-epi-Leukotriene B4 Endogenous Metabolite organic polymers are inherently biodegradable. Chitosan is readily compostable, and, consequently, their disposal will not be dangerous to nature [54]. The degradation of chitin and chitosan highlights their chance for recycling. One not too long ago explored organic polymer-based nanoparticulate matter incorporates cellulose nanocrystals (CNCs) (Figure 20). The development of chitosan and CNCs have already been proposed as active pads for meat packaging applications [55]. The inclusion of CNCs improved the pristine films’ mechanical properties, thermal stability, and oxygen barrier properties. Interestingly, the moisture retention potential from the films remained unhindered. The nanocomposites showedInt. J. Mol. Sci. 2021, 22,21 ofInt. J. Mol. Sci. 2021, 22, x FOR PEER REVIEWwide antimicrobial activity against Gram-positive and Gram-negative bacteria and 22 of 27 fungi (Candida albicans). Most importantly, the packages were able to prolong the shelf life in the meat merchandise under refrigeration by impeding the spoilage from the meats.Figure 20.
