This study investigated the feasibility of using Dracocephalum moldavica seed mucilage (DMSM) as anovel film-forming material. The chemical composition and functional group of the dried DMSM weredetermined. The DMSM films were prepared using three levels of glycerol (10–40%, w/w). The thermal,micro-structural, barrier, physical, and mechanical properties of the films and their antioxidant activitywere examined as a function of the glycerol concentration. As the concentration increased, the films’water vapour permeability, elongation at break (%EB), water solubility, and moisture content significantlyincreased. But the tensile strength, surface hydrophobicity, melting point, and glass transition point(Tg) decreased significantly. The films became slightly greenish or yellowish in colour but still lookedtransparent All the DMSM films displayed remarkable antioxidant activities. The electron micrographsshowed that the plasticized films had a uniform surface without any obvious cracks or pores. The resultsof the present study suggest that DMSM as a novel antioxidant edible film with interesting specificationscan be used to package several food products.
