摘　　要：Hylobius abietis is a plant parasitic insect belonging to the order Coleoptera and which causes severe damages to coniferous forests in Northern and Eastern Europe.This current study is aimed to provide a new viewpoint into the waste of this insect by producing chitosan.Dry insect corpses consisted of 27.9%chitin and 86.2%of the chitin was converted into the chitosan.FT-IR spectra analyses confirmed the purity and the deacetylation degree of the produced chitosan(molecular weight of chitosan;7.3 kDa).This chitosan exhibited antimicrobial activity against 18 bacterial strains.Further,biodegradable chitosan composite films with β-carotene were produced.Antioxidant activity of chitosan films were found to be higher than chitosan gels;andβ-carotene incorporation further increased the antioxidative properties of the chitosan films.This study demonstrated that the waste of parasitic insect like H.abietis can be evaluated as a source for production of biodegradable and edible chitosan-based films for applications in food coating.
