The possibility of usage of printed films with nanosized ZnO particles for detection of freshness/spoilage of packaged products was analyzed. The influence of model amines which emerge in meat and fish during storage on intensity of photoluminescence of nano-ZnO films was investigated. The luminescence is quenched more intensively with the increase of concentration of the amines, which enables determination of the stage of spoilage of packaged food. The processes that occur in ZnO nanoparticles contacting with amines were explained on absorption spectra.
