In the last years, nanotechnology progress has impacted several fields of food science. In food analysis, new nanomaterials have been developed in order to extract minority food components. Recently, magnetic nanoparticles (MNPs) have been used as sorbents in methodologies several fields of food science. Nowadays, magnetic sorbents, especially nanostructured ones, are widely used in sample preparation techniques as well as for removal of pollutants from the environment. Application of magnetic sorbents considerably simplifies the sample pretreatment process without filtering and centrifugation as well as ease recycle and reuse of the sorbent. Magnetic sorbents such as NPs, nanocomposites are generally used for preconcentration purposes. However, sponges, foams, hydrogel, and beads are generally used for removal purposes. Synthesis of novel magnetic hybrid sorbents by using advanced nanostructured materials such as MOFs, LDHs, G/GO, CNTs, COFs, RAM, MIPs and aptamers are being developed to find more efficient sorbents and introduce different extraction mechanisms at the same
