Abstract
The effects of nano titanium dioxide incorporation were investigated on the water vapor
permeability, oxygen permeability, and antimicrobial properties of bovine gelatin films. The nano TiO2 (TiO2-
N) was homogenized by sonication and incorporated into bovine gelatin solutions at different concentrations
(e.g. 1, 2, 3, and 5% w/w of dried gelatin). The permeability of the films to water vapor and oxygen was
significantly decreased by incorporating of low concentration TiO2-N to gelatin solutions. TiO2-N gelatin films
showed an excellent antimicrobial activity against Staphylococcus aureus and Escherichia coli. These
properties suggest that TiO2-N has the potential as filler in gelatin-based films for using as an active packaging
materials in pharmaceutical and food packaging industries.
