Novel postharvest technologies for prolonging fruit shelf life in Japan
Abstract:
In order to prolong the shelf life of highly perishable fruits and vegetables, new technologies should be introduced during storage and transportation. Temperature control is surely important for keeping freshness and quality higher. In addition, both humidity and microbial controls are also playing important role for avoiding the wilting, discoloration, microbial growth, etc. The nano-sized mist is generated by Lenard effect with high speed impact of water droplet to metal mesh. The peak diameter of mist is approximately 80 nm, which is roughly several times smaller than that of the normal mist for humidity control of fresh produces generated by ultrasonication. The nano-sized mist has the advantage for preventing over-wetting which results in the collapse of cardboard even with high relative humidity environment, whereas no considerable effects on the physiological responses of fresh produces were found.Infrared/Ultaviolet treatment was applied to the decontamination process of microbes infecting the surface of fresh produces. A 1-1.5 logs reduction of surface microbe of fruits was obtained by infrared or ultraviolet treatment individually. In addition, another 1-2 logs reduction were enhanced by their combination without negative effects on surface color, hardness, and respiration.
