“…In addition, the generated •OH radicals for the G-SF/PVA BNM at different time intervals were detected by a DMPO-trapping ESR technique. As displayed in Figure 5d, the ESR spectra possessed a 1:2:2:1 quartet pattern, and the intensity of the peaks was enhanced with the increasing reaction, which confirmed the formation of the •OH radicals [38,39]. To evaluate the antibacterial activity of the G-SF/PVA BNM, typical pathogenic bacteria, Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus), were employed to examine the photoactive membranes.…”

Antibacterial materials that prevent bacterial infections and mitigate bacterial virulence have attracted great scientific interest. In recent decades, bactericidal polymers have been presented as promising candidates to combat bacterial pathogens. However, the preparation of such materials has proven to be extremely challenging. Herein, photoactive silk fibroin/polyvinyl alcohol blended nanofibrous membranes grafted with 3,3’,4,4’-benzophenone tetracarboxylic dianhydride (G-SF/PVA BNM) were fabricated by an electrospinning technique. The premise of this work is that the G-SF/PVA BNM can store photoactive activity under light irradiation and release reactive oxygen species for killing bacteria under dark conditions. The results showed that the resultant G-SF/PVA BNM exhibited the integrated properties of an ultrathin fiber diameter (298 nm), good mechanical properties, robust photoactive activity and photo-store capacity, and great photoinduced antibacterial activity against E. coli and S. aureus (99.999% bacterial reduction with 120 min). The successful construction of blended nanofibrous membranes gives a new possibility to the design of highly efficient antibacterial materials for public health protection.

“…Even after 5 cycling runs, the CWPO efficiency remained at over 95%, showing the extraordinary stability of Fe-PAN. In previous research studies, 19,29,43,58 there was more or less a loss of activity of the catalysts after each cycle. The reasons for this could be the leakage of active species, the change in the membrane structure, or the deposition of intermediates and byproducts.…”

“…As one of the edible film materials, chitosan is a common active packaging material (Gomes et al, 2018) with the advantages of safety, non-toxicity, good film-forming property, and bacteriostasis (Yi et al, 2020). The antibacterial activity and film-forming properties of chitosan make it an attractive biopolymer for food packaging and preservation.…”

Due to the easy spoilage of meat products and the improper preservation and transportation technology, the loss rate of meat is relatively high. Most of the fresh‐keeping films are made by adding natural antioxidants and various film‐forming methods. This study expounds the latest progress in the application of antibacterial and antioxidant packaging materials in meat products. With the addition of antibacterial and antioxidant active substances to the packaging, challenges regarding the stability, safety, compatibility and regulations of active substances emerge. This research status in the direction of prospects and challenges about antibacterial and antioxidant packaging materials for meat.
