Abstract
- This study aims to prepare binary edible films made from carboxymethyl cellulose (CMC) and chitosan biguanidine hydrochloride (CBg) activated with frankincense oil (FO). The interactions between CMC, CBg and FO were confirmed by FTIR. XRD showed that the addition of FO led to decreasing the crystallinity of CMC/CBg films. The water vapour permeability was reduced upon increasing the FO content. The presence of FO made the films brighter and didn't change their transparency as detected from the color measurements. The films exhibited better mechanical properties in the presence of FO as detected from the improved values of both tensile strength and elongation at break. The prepared films exhibited excellent antibacterial activity especially at high content of FO (5%). CMC/CBg/FO films might be used potentially in the production of edible films due to their excellent physical and antibacterial properties. • Novel edible films from carboxymethyl cellulose (CMC), chitosan biguanidine (CBg) and frankincense oil (FO) were prepared. • Films exhibited a reduced water vapor permeability. • FO did not affect the color or the transparency of the films. • Films mechanical and antibacterial properties were improved with increasing the FO percent. • CMC/CBg/FO can be used as antibacterial edible films with excellent physical properties.
