“…With regard to electrospinning, numerous studies have reported that the low viscosities of pure zein solutions cause them to exhibit poor electrospinnability . Although in our previous studies we have shown that electrostatic interaction between ASKG and zein leads to the formation of core–shell nanoparticles, further research is needed for fabrication of their nanofibers. As shown in Figure a, the low viscosity of the Z@A solution leads to the formation of spindle fibers.…”

“…Zein contains numerous active functional groups, particularly sulfhydryl groups, that can interact with ethylene. As reported in our previous studies, , the active functional groups of zein can be used to enhance the ethylene removal efficiency. However, the pure zein nanofibers are difficult to fabricate via electrospinning owing to the low viscosity of zein solutions leading to poor spinnability …”

“…The viscosities of the precursor solutions gradually increased with the incorporation of CS, and the electrostatic co-assembly between zein, ASKG, and CS led to the formation of core–shell (zein as the shell and ASKG and CS as the core) bead-free nanofibers with a smooth cylindrical shape. In our previous studies, we found that the porous structure of a paper towel provides favorable mechanical support to nanofibers, and thus, the electrospun Z@A-CS nanofibers were deposited onto a paper towel as shown in Figure b. Thus, the core–shell structure and smooth morphology of the electrospun fibers exhibit high potential for the development of bio-based ethylene scavenger films for fruit preservation.…”

Ethylene scavengers exhibit considerably high potential for their application in prolonging the shelf-life of fruits, but their application has been hindered owing to food safety and environmental issues. Thus, in this study, we fabricated a bio-based nanofiber film composed of zein, Artemisia sphaerocephala Krasch. gum (ASKG), and chitosan (CS) via electrospinning. The addition of ASKG and CS increased the viscosity and surface tension of zein precursor solutions and consequently enhanced their spinnability. Electrostatic co-assembly between the protein and polysaccharides led to the formation core–shell nanofibers (Z@A-CS nanofibers), which effectively enhanced their ethylene removal efficiency, mechanical properties, and hydrophobicity. Furthermore, bananas incubated with the Z@A-CS nanofiber films for 10 days exhibited a lower browning rate, higher hardness, and prolonged shelf-life compared to those incubated without a film. Based on these results, we deduce that the strong interactions between the numerous active functional groups of zein and ethylene and the large specific surface area of the nanofibers led to the development of highly efficient, environmentally friendly, and economical ethylene scavenger films, which exhibit a high potential in fruit preservation.

Ethylene scavenging‐active packaging is getting more interest to reduce postharvest losses of ethylene‐sensitive produce to overcome the limitations of traditional postharvest technologies. The aim of this study is to monitor behaviour of ethylene‐sensitive products to different ethylene scavenging systems combined with modified atmosphere packaging (MAP). Banana (Musa paradisicum L. var. Anamur) and kiwi (Actinidia deliciosa L. var. Hayward) were packaged with low‐density polyethylene (LDPE) bags containing ethylene scavenging sachet and ethylene scavenging‐active LDPE bags. Only passive MAP was used for bananas stored at 13°C for 12 d. Both passive and active MAP (5% O2, 5% CO2) were used for kiwi stored at 4°C for 30 d. LDPE bags with no ethylene absorber and unpackaged produces were the control groups. O2, CO2 and ethylene concentrations, mass loss, texture, colour, TSS %, titratable acidity and sensory analysis were performed during storage. O2% in the control LDPE bags decreased below 2% on 6th d, while LDPE bags containing sachet and active LDPE bags remained above critical O2 level for bananas during the entire storage. The lowest ethylene concentration was 0.45 μl L−1 in both active systems on 12th d. Equilibrium atmosphere was maintained in active and passive MAP after 5th d for kiwifruit. The lowest ethylene concentrations were determined as 0.47 μl L−1 and 0.50 μl L−1 in the sachet included LDPE and active LDPE, respectively under passive MAP at the end of the storage. In conclusion, bananas packaged with both active systems were acceptable for 9 d considering physicochemical and sensory properties. The kiwifruit was acceptable for 30 d using both ethylene absorbing systems under passive MAP.
