Abstract: Tests of five kinds of nano-structural metal oxide’s antibacterial effects on five species of bacterium in contaminatied food were made by cup-dish measure and tube diploid dilute method. We have also measured the resistance diameter of five kinds of nano-structural materials against five kinds of bacteria. The results revealed that nano-ZnO was the most effective antibacte- rial agent. Then the MIC value (microbial inhibition concentration) to these 5 Species of bacterium were detected. We also discussed antibacterial mechanism of nano-ZnO and its further application in food antibacterial packaging field.

Key words: nano-structural metal oxide, food contamination bacteria, MIC
