Physical, barrier and antioxidant properties of a novel plasticized edible film from quince seed mucilage.
In this study, we investigated the potential of quince seed mucilage (QSM) as a new source for preparation of edible films and determined the physical, mechanical, barrier, antioxidant, microstructural and thermal properties. QSM films were prepared by incorporation of three levels of glycerol (25-50%, w/w). As glycerol concentration increased, water vapor permeability (WVP), oxygen permeability (O2P), elongation at break (EB), water solubility and moisture content of QSM films increased while, tensile strength (TS), density and surface hydrophobicity decreased significantly. The measurement of color values showed that by the increasing of the glycerol concentration in polymer matrix, the b and L values increased while ΔE value decreased. Microscopic views indicated smooth and uniform surface morphology without obvious cracks, breaks, or openings on the surfaces after the incorporation of glycerol as a plasticizer. The results of the present study suggest that QSM as a new antioxidant edible film with interesting specifications can potentially be used for packaging of a wide range of food products.
