N2 - To exploring a nano-packaging materials for using as coating or edible films, tapioca starch/gelatin/nanorod ZnO (ZnOsingle bondN) bionanocomposites were prepared via solution casting technique. The effects of nanofiller addition on the mechanical, physicochemical, and crystalline structures, as well as the barrier properties of bionanocomposite films were investigated. X-ray diffraction analysis showed that the bionanocomposite film incorporated with ZnOsingle bondN at a concentration of 3.5% w/w exhibited high intensity peaks compared with control samples. Results of UV–vis spectra analysis showed that incorporation of ZnOsingle bondN into the films can absorb the whole UV light. Tensile strength of the films was increased from 14 to 18 MPa whereas elongation at breaks decreased from 18 to 8 percent and oxygen permeability decreased from 151.03 to 91.52 cm3 μm/(m2–day) by incorporation of 3.5% ZnOsingle bondN into biopolymer matrix. In summary combined starch/gelatin films supported by ZnOsingle bondN showed better properties compared to starch or gelatin alone. Thus, the bionanocomposite films can be used in food, medicine, and pharmaceutical packaging.
