Ameliorating characteristics of magnetically sensitive TPU nanofibers-based food packaging film for long-life cheese preservation

The current study presents magnetic nanoparticles (MNPs) dispersed polyurethane (PU) nanofiber nanocoating with exceptional magnetic, thermal, hydrophobicity, and textural properties. X-ray photoelectron spectroscopy (XPS) was used to clarify the Fe3O4 MNPs synthesis, which had previously been accomplished using a single-step green method using molasses as a biowaste. The MNPs particles were then encapsulated in PU nanofibers with varying concentrations of 0.1, 0.3, and 0.5 wt%. SEM revealed a homogenous, smooth, and consistent fiber morphology with a diameter of 173.61 (size, nm), and the diameter rises with the addition of MNPs. With statistical significance (P
