As part of the research, chitin materials were obtained using the electrospinning method. For this purpose, chitin solutions were prepared in phosphoric acid and lithium chloride in an am-ide solvent. The coagulation of chitin materials was performed in alkaline water baths and in distilled water. As a result of the method, microspheres and microfibers of chitin were ob-tained. The morphological structure of the obtained materials was analyzed using a scanning electron microscope (SEM) and an optical microscope. The obtained microspheres were characterized by a similar diameter value, amounting to 195 μm. In contrast, chitin microfi-bers from 90 to 150 μm. The obtained materials were subjected to mid-infrared and Raman spectrophotometric tests in order to determine the influence of the solvents used on the chemical structure of native and regenerated chitin. Infrared spectroscopy studies confirmed no changes in the chemical structure of regenerated chitin. Raman spectroscopy studies confirmed no degradation of regenerated chitin. In the spectra obtained, differences were observed in the form of changes in the shape of the bands for oscillators be associated in in-termolecular interactions, which is caused by changes in the supermolecular structure.
