Abstract: Nano-titanium dioxide photocatalysis (TPC) technology has become a hot research topic as an emerging non-thermal technology. TPC technology has been widely used in non-thermal food processing due to its high antibacterial activity, chemical stability, non-toxicity, environmental friendliness, and low cost. TPC technology can be widely used for the sterilization of foods due to the production of active substances such as singlet oxygen, superoxide anion radicals and hydroxyl radicals during the catalytic process. This paper outlines the principle and bactericidal mechanism of TPC technology, reviews its application in food packaging, discusses possible strategies for improving the photocatalytic efficiency of nano-titanium dioxide, and evaluates the safety of TPC technology. Finally, future research and application directions are proposed. The purpose of this paper is to provide a theoretical basis and technical supports for the application and promotion of TPC technology in food research.

Key words: nano-titanium dioxide photocatalysis technology, photocatalytic mechanism, antibacterial mechanism, food packaging
