Magnetic separation of nanobiostructured systems for innovation of biocatalytic processes in food industry

Magnetic nanoparticles have been studied due to their attractive properties and because they can be manipulated using a magnetic field. Actually, they are utilized in many fields and applications such as catalysts for chemical reactions, in magnetic resonance imaging, in biomedicine, as sensors, in nanofluids, and in environmental remediation. Most applications are based on the possibility to develop magnetic separation carriers in several processes. Some catalysts (enzymes) applied in the food industry can be immobilized onto magnetic nanosupports to be recovered and reused in repeated cycles of catalysis. This chapter presents an analysis of methods for enzyme immobilization onto magnetic nanoparticles. It is hoped that the use of magnetic nanosupports will lead to the development of more efficient, economical, and environmentally friendly technological processes applied to the food industry.
