Keywords: superparamagnetic nanomaterial, iron oxide nanoparticles, enzyme immobilization, β-glucosidase, debittering olives

The aim of this study is to develop stable superparamagnetic iron oxide nanoparticles (SPIONs) for the immobilization of β-glucosidase. The goal is to figure out the possibility of applying immobilization techniques in the debittering of olives. In the present study, SPIONs with a size of ~9 nm were synthesized by co-precipitation, and immobilization was carried out by the formation of covalent bonds between β-glucosidase and SPIONs. The properties of the free enzymes immobilized with SPIONs were compared by using commercial β-glucosidase as a standard. The immobilized enzymes were characterized by using techniques including X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and transmission electron microscopy (TEM). The results showed that SPIONs are an effective and suitable material for the immobilization of β-glucosidase as well as a potential nanomaterial for the elimination of olive bitterness originating from oleuropein.
