The biodegradable blends of chitosan and starch with different component ratios were prepared by casting method. Obtained thin films were UV-irradiated (λ = 254 nm) and changes in chemical structure were monitored using FTIR and UV-Vis spectroscopies. It was found that the chitosanstarch blends were more susceptible to UV irradiation comparing to pure starch specimen. FTIR spectra of blends suggest partial interactions between chitosan and starch macrochains.
