Physicochemical properties of Carum copticum essential oil loaded chitosan films containing organic nanoreinforcements.
The aim of this research was to prepare of bionanocomposite films based on chitosan (CH) incorporated with Carum copticum essential oil and reinforced with cellulose nanofibers (CNF) or lignocellulose nanofibers (LCNF). The FTIR analysis showed new interactions in bionanocomposites. AFM and SEM analyses showed an increased roughness for bionanocomposites but suggested good dispersion of CNF and LCNF in CH matrix. X-ray diffraction confirmed that the degree of crystallinity was increased by addition of CNF/LCNF. The results suggested that the CH-EO film had high antioxidant activity and was more effective against E. coli and B. cereus bacteria than CH-EOCNF and CH-EO-LCNF films, which shows the release controlling effect of nanofibers. Mechanical properties were improved with addition of EO and CNF/LCNF. Incorporation of EO and CNF/LCNF improved water vapor barrier properties of films. In general, uniform dispersion and improving effect of LCNF on properties of CH-EO films was more than CNF.
