“…The results of mechanical tests for each group of specimens are shown in Table 2. The test results indicated that the CZP composite membranes maintained the maximal tensile strength and elongation, possibly because ZnO can impart a better tensile strength and toughness to composite membranes [58]. In chitosan/cellulose membranes, the tensile strength was increased significantly with the increase of added membrane solution, while the elongation was not changed.…”

In this study, chitosan and sugarcane cellulose were used as film-forming materials, while the inorganic agent zinc oxide (ZnO) and natural compound phenyllactic acid (PA) were used as the main bacteriostatic components to fabricate biodegradable antimicrobial composite membranes. The water absorption and antimicrobial properties were investigated by adjusting the concentration of PA. The scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) results demonstrated that the components of the composite membrane were successfully integrated. The addition of ZnO improved the mechanical and antimicrobial properties of the composite membrane, while the addition of PA with high crystallinity significantly reduced the water absorption and swelling. Moreover, the addition of 0.5% PA greatly improved the water absorption of the composite membrane. The results of antimicrobial experiments showed that PA improved the antimicrobial activity of the composite membrane against Staphylococcus aureus, Escherichia coli, Aspergillus niger and Penicillium rubens. Among them, 0.3% PA had the best antimicrobial effect against S. aureus, E. coli and A. niger, while 0.7% PA had the best antimicrobial effect against P. rubens.

“…The group composition of the RP was extracted using Fourier transform infrared (FTIR) spectroscopy (Suzhou Leiden Scientific Instruments Co., Ltd., Suzhou, China) with the tablet method. Each protein-powder sample was tested twice, and 32 scans with a resolution of 4 cm −1 were obtained over a wavenumber range of 500–4000 cm −1 ( Zhang et al, 2021 ).…”

“…Biodegradable polymer matrices have been an ecofriendly and widely applied alternative for preparing antibacterial films based on ZnO NPs (Râpă et al, 2021;Sun et al, 2020b). Recently, Zhang et al (2021a) ultrasonically dispersed ZnO NPs in PLA matrices to produce antimicrobial fibrous membranes by electrospinning. The results showed the best performance when the ZnO content was 0.5 wt% in PLA/ZnO films.…”

Inorganic nanoparticles (NPs) and natural antioxidant compounds are an emerging trend in the food industry. Incorporating these substances in biobased and biodegradable matrices as polysaccharides (e.g., starch, cellulose, and chitosan) and proteins has highlighted the potential in active food packaging applications due to more significant antimicrobial, antioxidant, UV blocking, oxygen scavenging, water vapor permeability effects, and low environmental impact.
