“…Friction between fibers increases with the thickness of the membrane, which makes thicker membranes more prone to fracture [ 41 ]. Zhu et al [ 42 ] reported an electrospun fiber membrane with good mechanical properties, including a tensile strength of 0.8 MPa and an elongation at break of 16%. Zhang et al [ 43 ] also reported an electrospun fiber membrane with a tensile strength of 0.89 MPa and an elongation at break of 8.99%.…”

Rapid social and industrial development has resulted in an increasing demand for fossil fuel energy, which increases particulate matter (PM) pollution. In this study, we employed a simple one-step electrospinning technique to fabricate polysulfone (PSF) fiber membranes for PM filtration. A 0.3 g/mL polymer solution with an N,N-dimethylformamide:tetrahydrofuran volume ratio of 3:1 yielded uniform and bead-free PSF fibers with a diameter of approximately 1.17 μm. The PSF fiber membrane exhibited excellent hydrophobicity and mechanical properties, including a tensile strength of 1.14 MPa and an elongation at break of 116.6%. Finally, the PM filtration performance of the PSF fiber membrane was evaluated. The filtration efficiencies of the membrane for PM2.5 and PM1.0 were approximately 99.6% and 99.2%, respectively. The pressure drops were 65.0 and 65.2 Pa, which were significantly lower than those of commercial air filters. Using this technique, PSF fiber membrane filters can be easily fabricated over a large area, which is promising for numerous air filtration systems.

“…On the other hand, the incorporation of nisin resulted in increased antibacterial activity against various microbial strains (Tajfiroozeh et al 2023). Zhu et al (2023) also explored the coaxial electrospinning technique to incorporate thymol into PEO/CH to form core-shell nanofibers. The crosslinker-genipin, a chemical agent enabling the bonding of polymer chains, was also encapsulated into the core layer for in-situ crosslinking with the CH during the electrospinning process.…”

“…The crosslinker-genipin, a chemical agent enabling the bonding of polymer chains, was also encapsulated into the core layer for in-situ crosslinking with the CH during the electrospinning process. These crosslinked core-shell nanofibers exhibited improved mechanical properties, thermal stability, and sustained release profiles, as well as antioxidant activity, besides effective growth inhibition of common food spoilage bacteria (Zhu et al 2023). Dede et al (2022) explored the emulsion electrospinning technique to prepare edible active food packaging materials encapsulating basil oil, which contains several allyl-phenol derivatives, one of which, estragole, has antibacterial activity against a wide variety of bacteria, yeast, and mold (Dede et al 2022).…”

In response to escalating concerns about environmental pollution from conventional plastic packaging, there is a growing interest in ecological and sustainable materials for food packaging. Consequently, biopolymer-based electrospun materials, particularly polysaccharides such as chitosan (CH), starch, and cellulose, have emerged as promising alternatives to synthetic ones due to their remarkable barrier properties and mechanical strength. Moreover, following the trend of employing polysaccharides as ecological and sustainable solutions for packaging materials, natural colorants have also been recognized as safer alternatives to synthetic dyes, addressing concerns about potential adverse effects on human health and the environment. These natural colorants add color to food packaging and enhance food freshness, possibly extending shelf life and promoting consumers' perception of food quality and safety. Therefore, this review summarizes recent advancements in fabricating and characterizing electrospun materials based on polysaccharides and natural colorants for sustainable food packaging. It explores various electrospinning techniques and highlights the incorporation of natural colorants, including bacterial pigments, for active and intelligent packaging applications. Moreover, it emphasizes the increasing role of the biobased industry in developing sustainable packaging materials with bioactive coloration. Lastly, the review addresses challenges, opportunities, and future research directions. Graphical Abstract

Cross-linkers are pivotal to meliorate the attributes of the biopolymers, which are exploited in the biomedical industries, and also those intended as packaging supplies. Genipin (GN) is an efficacious cross-linker. Moreover, being naturally procured, biodegradable and biocompatible makes it an auspicious candidate for the biomedical and food industries. Accordingly, we attempted to provide a comprehensive review on GN as an efficient cross-linker for biopolymers. Initially, we presented the chief botanical sources of GN. The GN extraction strategies, which adopted safe solvents, were then discussed while highlighting their realized yields. The proposed GN structures, its possible modes of action, and the factors affecting its interactions, such as pH, temperature, and GN concentration were also reviewed. Afterward, the GN applications that mainly involved cross-linking biopolymers and biopolymers containing materials were discussed. These included tissue engineering, wound dressings, drug delivery, and packaging applications. GN capability to activate biopolymers, such as chitosan and gelatin, into covalently reactive enzyme immobilizers was also discussed. Moreover, other important GN applications, such as exploiting it as a colorant for foods and textiles and incorporating it in altered biosensors, were discussed.
