摘　　要：为了探究以UVC-LEDs为光源的紫外辐照技术在芒果贮运保鲜中的应用性能,设计了一款便携式食品杀菌保鲜装置。使用该装置对“台农一号”芒果进行紫外线杀菌,并比较不同剂量紫外辐照对芒果感官特征的影响。结果表明,UV-C处理可以推迟芒果病斑出现的时间,其中,161 mJ/cm^(2)剂量的紫外线辐照可以将芒果保鲜期延长3~4 d。以UVC-LEDs为光源的便携式食品杀菌保鲜装置对芒果的保鲜效果较好,可为今后食品杀菌保鲜产品的应用开发提供依据。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 preservation device was designed based on UVC-LEDs.The device was used to sterilize“Tainong-1”mango under 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 lesions,and a dose of 161 mJ/cm^(2)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 sterilization and preservation products in the future.
