Effect of UVC-LEDs irradiation on storage period of mango
In order to explore the application performance of UV irradiation technology using UVC-LEDs as the light source in mango storage,transportation,and preservation,a portable food sterilization and preser-vation device was designed based on UVC-LEDs.The device was used to sterilize"Tainong-1"mango un-der UV irradiation,and the effects of different doses of UV irradiation on the sensory characteristics of mango were compared.The results showed that UV-C treatment can delay the appearance of mango le-sions,and a dose of 161 mJ/cm2 of ultraviolet radiation can prolong the storage period of mango by 3～4 days.The portable food sterilization and preservation device with UVC-LEDs as the light source has a good preservation effect on mango,which provides a basis for the application and development of food steri-lization and preservation products in the future.
