NanoAbsorbant is a product partly composed of TiO2 photocatalyst and copper nano particles and is applied in agricultural products packaging. Its function includes oxidation of reeked ethylene from the fruits and vegetables in the package and as a result increasing their durability,increasing carbon dioxide gas concentration and as a result preserving fresh taste of the fruits,increasing humidity and as a result keeping the fruits and vegetables fresh and juicy and preventing the growth of bacteria and fungi. So it could be claimed that in packages which can exchange air with the ambient,NanoAbsorbant acts similar to Atmosphere Control method and this can be used in preserving the quality of agricultural products in packaging,transportation and export.
