摘要：The comparative effect of gamma irradiation doses (0.5 kGy), UV-C-30 min and hot water 55°C-10 min on fungal load and aflatoxin production was evaluated on mango (black chaunsa). Thirteen fungal species were isolated from the surface of mango fruits ( Mangifera Indica L.), among these the frequency of Aspergilus niger , Aspergillus flavus and Cladosporium cladosporoides was higher. Fungal load can be controlled best by using gamma rays at 0.5 KGy dose level followed by UV-C irradiation treatment while maximum load was found in control group. It appeared that non thermal techniques (gamma irradiation and UV-C) are comparatively better over control and conventionally used hot water treatment. Regarding the production of aflatoxins by these isolates, gamma irradiation treated samples showed less production of aflatoxin. Based on these results gamma irradiation and UV-C treatment possess the potential to replace conventionally used hot water treatment in mango.
