Abstract
<p>Nanoparticles are smaller than 100nm. Size of particle depends upon the method that is used for synthesis of nanoparticles. Magnetic nanoparticles consist of iron, cobalt and nickel and their chemical compounds. Their safety or toxicity is major concern for use in food. Magnetite, hematite and meghemite are types of magnetic nanoparticles. Magnetite (Fe3O4) common among the magnetic iron oxide nanoparticle that is used in food industry. Magnetite is getting popular due to its super paramagnetic properties and lack of toxicity to humans. Different methods are used to synthesize magnetic nanoparticles. Upon contact with air these particles loses magnetism and mono-dispersibility. To overcome this problem these nanoparticles are coated with natural or synthetic polymers, metals, organic and inorganic substances to create stable and hydrophilic nanostructures. Due to easy separation with magnet these magnetic nanoparticles are used as an affinity probe to remove bacteria from different food samples and have food related applications e.g, protein purification, enzyme immobilization and food analysis. These magnetic nanoparticles also used for removal of heavy metals and used in medical field.</p>
