Abstract
tThe present work introduces the structure and physicomechanical properties of a novel blend film madefrom binary solutions of gum tragacanth (GT) and locust bean gum (LBG) at different mixing ratios.Apparent viscosities and surface tensions of individual and blend gum solutions were also investigated.The viscosity data indicated that there was a distinct synergism between the two gums at all mixingratios. FTIR spectra showed the existence of noncovalent intermolecular interactions between gums.The surface tensions of binary solutions were significantly lower than those of individual gums which isadvantageous for coating applications. All films had homogenous and smooth surface morphology andtheir transparency, water vapour barrier and mechanical properties were improved by incorporating LBGin blend. The results of this study suggest that GT–LBG blend film, owing to its desirable properties, hasthe potential to be used as a new degradable food packaging material.
