Abstract

Graphical abstract: Highlights: TiO2 photocatalysis-based systems applied on postharvest of fruits are detailed. The photocatalytic degradation of ethylene postpones the fruit ripening. TiO2 photocatalysis is promising for applications in small and large scales. Abstract: Titanium dioxide (TiO2 ) is a photocatalytic material used to degrade ethylene, and it has been studied as an alternative postharvest technology. Although several studies have indicated the effective action of TiO2 photocatalysis for delaying the fruit ripening, photocatalytic systems need to be well-designed for this application. Fruit is susceptible to environmental conditions like temperature, relative humidity, atmosphere composition and exposure to UV-light. This fragility associated with its variable ethylene production rate over its maturation stage limits the photocatalysis parameters optimization. Thus, this review aims to detail the reaction mechanisms, set-up, advantages, and limitations of TiO2 photocatalytic systems based on polymers-TiO2 nanocomposites and reactors containing TiO2 immobilized into inorganic supports designed for fruit applications. It is expected that this review can elucidate the fundamental aspects that should be considered for the use of these systems.
