Titanium dioxide (TiO2) shows antibacterial effects when exposed to near ultra violet (UV) light. In this study,TiO2 photocatalytic continuous reactor was designed and applied to food-borne pathogens such as Vibrio parahaemolyticusATCC 17802, Salmonella choleraesuis ATCC 14028, and Listeria monocytogenes ATCC 15313. TiO2 films were prepared byconventional sol-gel dip-coating method using titanium tetra iso-propoxide (TTIP). The antibacterial activity of photocatalyticreactor with various flow rates and UV-A illumination time showed effective bactericidal activity. As the UV-A illuminationtime increased, survival rates of those bacteria decreased. After 60 min of UV-A illumination, the survival rates of V.parahaemolyticus and S. choleraesuis were less than 0.1%. However, that of L. monocytogenes was about 5% at that timepoint. These results present an effective way to exclude pathogenic bacteria from aqueous foods.
