Abstract: Nano-TiO2 was modified on its surface by chemical liquid deposition with SiO2 and the dispersion properties were studied. Its inhibitory capacity against mould during storage of citrus was studied by the method of Oxford-cup test and the antibacterial mechanism was discussed. The results showed that attached silicon dioxide can reduce the product size and improve stability and dispersity of nano-TiO2 in water. The composite material doped with SiO2 has outstanding antibacterial activities and has less influence on antibacterial activity.

Key words: nano-TiO2, citrus, mould, antibacterial activity
