title: Development of bacterial cellulose based slow-release active films by incorporation of Scrophularia striata Boiss. extract.
abstract: Novel bacterial cellulose (BC) based monolayer and multilayer films, incorporating 5wt.% Scrophularia striata Boiss. extract (SE) were obtained. The effect of lamination and β-cyclodextrin (β-CD) inclusion complexation of SE on morphological, physical, antioxidant and release properties of films were investigated. FT-IR results reflected that some new interactions have occurred between BC and β-CD. The XRD analyses showed a decrease in diffraction intensities of BC by addition of free SE. SEM results indicated that the intrinsic compactness of the BC film was preserved by addition of SE/β-CD complex. Lamination and SE/β-CD addition enhanced the mechanical properties. SE loaded films exhibited a good antioxidant activity. Release studies indicated that the release rate and diffusion coefficient (D) of SE in 95% ethanol simulant were significantly decreased by lamination and complexation of SE with β-CD. Results suggest that SE loaded BC films may be used as controlled release antioxidant food active packaging.
