Novel bacterial cellulose (BC) based monolayer and multilayer films, incorporating 5 wt.% Scrophulariastriata Boiss. extract (SE) were obtained. The effect of lamination and -cyclodextrin (-CD) inclusioncomplexation of SE on morphological, physical, antioxidant and release properties of films were investi-gated. FT-IR results reflected that some new interactions have occurred between BC and -CD. The XRDanalyses showed a decrease in diffraction intensities of BC by addition of free SE. SEM results indicatedthat the intrinsic compactness of the BC film was preserved by addition of SE/-CD complex. Laminationand SE/-CD addition enhanced the mechanical properties. SE loaded films exhibited a good antioxidantactivity. Release studies indicated that the release rate and diffusion coefficient (D) of SE in 95% ethanolsimulant were significantly decreased by lamination and complexation of SE with -CD. Results suggestthat SE loaded BC films may be used as controlled release antioxidant food active packaging.
