The present work demonstrates the formulation of cellulose nanofiber (CNF) or magnetic (mgCNF) dispersed chitosan-based edible nanocoating with superior mechanical, thermal, optical, and texture properties. fabrication mgCNF is successfully achieved through a single-step coprecipitation route, where iron particles get adsorbed onto CNF. thermal stability improved considerably, ∼17% reduction in weight observed, whereas CNF degrades completely under identical conditions. TGA analysis shows that there an improvement for both CNF- mgCNF-reinforced CS nanocoatings, provides more heat dimensional than CNF-dispersed nanocoatings. Further, nanocoatings are stable even at temperature treatment such as food sterilization. mechanical property mgCNF-dispersed chitosan (CS) remarkable tensile strength (57.86 ± 14 MPa) Young's modulus (2348.52 276 comparison to neat (6.27 0.7 462.36 64 MPa, respectively).
