摘要: 本文选择5种纳米级金属氧化物,针对5种常见的食品污染菌,分别采用杯碟法和试管双倍稀释法进行抑菌效果研究,检测出几种纳米金属氧化物对各种细菌的抑菌圈直径,并检测出抑菌性能最好的纳米ZnO对各种细菌的MIC值。探讨了纳米氧化锌抗菌机理及在食品抗菌包装领域的应用前景。
关键词: 纳米金属氧化物, 食品污染菌, MIC
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
