摘　　要：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<0.05),PU/MNPs nanofiber showed intense antibacterial activity against different microbes.Notably,PU/0.5 wt%MNPs exhibit advantages as antimicrobial packaging materials by maintaining the quality and freshness of the Karish cheese and extending its shelf life to 40 days while also boosting its gumminess(5.9,N),hardness(7.93,N),cohesiveness(0.6),and adhesiveness(1.14,mg).Iron content is quantified using inductively coupled plasma mass spectrometry(ICP-MS)to determine whether the developed materials are safe for food.These findings showed that PU/MNPs could be a valid alternative for controlling Karish cheese storage.Further research into the effectiveness of this method with various smear cheeses is possible.
