REVIEW ON TiO2-BASED PHOTOCATALYST FOR FOOD PACKAGING APPLICATION: REMOVAL OF ETHYLENE AND ANTIBACTERIAL

Abstract

TiO2-based photocatalysts have been widely applied in various fields such as the energy crisis, environment remediation, medical, building, and so on. Recently the applications of TiO2- based photocatalysts have developed for the food industry as smart materials to store foods and increase the shelf line of foods. In this review, we evaluate the recent application of TiO2-based photocatalyst for the decomposition of ethylene gas to inhibit fruit ripening as well as antibacterial. The photocatalytic performances under varying conditions for the removal of ethylene and antibacterial were discussed. The mechanism for ethylene degradation, antibacterial, and potential application of TiO2-based photocatalyst in food packaging have been suggested.
