improved physicochemical properties of tapioca starch / bovine gelatin biodegradable films with zinc oxide nanorod
نویسندگان
چکیده
the effects of zinc oxide nanorod (zno-n) incorporation on thephysicochemical properties of tapioca starch / bovin gelatin composite film such as water absorption capacity (wаc), water solubility and permeability to water vapour (wvp) were investigated. in this search, zno-n was homogenized by sonication and added into tapioca starch / bovine gelаtin dispersions аt different concentrations (e.g. 0.5, 2, and 3.5% w/w total solid). incorporation of 3.5% of nanoparticles to tapioca starch / bovine gelatin films decreased the permeability to water vapor by 18%. water absorption capacity and solubility of the films were decreased by increasing the zno-n contents. these properties suggest that zno-n has the potential as filler in starch /gelatin-based films for using in pharmaceutical and food packaging industries
