АbstractThe goal of research is the mechanism study of interaction of Fe 3 O 4 nanoparticles ("Magnetofood" food additive) with linoleic acid and sunflower oil which is represented by the "Two-layer coordination" model.The chemical composition of the surface layers and the chemical state of elements on the surface ofFe 3 O 4 nanoparticles coated with linoleic acid and unrefined sunflower oil was studied by X-ray photoelectron pectroscopy.It was established that on the spectra lack the C 1s absorption band at 290 eV which corresponds to carboxyl carbon (-COOH), that is, there is no Estern group.Thisallows for the conclusionabout the fat-binding and fatcontentingcapacity of the nanoparticles of"Magnetofood" food additive.
