cv. Unicorn) by ultraviolet light (UV-C) irradiation in MA storage. Hydroponic grown red maturity stage of cherry
tomatoes was collected from Gangwon province. Tomato fruits were inoculated with Botrytis cinerea (grey mould).
Afterwards, ultraviolet irradiation (254 nm, UV-C) of 7, 14, 21 and 28 kJ/m2 treated to tomato fruits. And treated
UV-C tomatoes were packed with MA condition (20,000 cc/m2. day.atm O2 permeability film) to store at 5˚C for 20
days with 85% relative humidity. The 28 kJ treatment which showed the best visual quality maintained around
3.30-6.60% of carbon dioxide concentration and 16.08-17.50% oxygen and 0.26-1.11 µL/L ethylene during the
storage. As storage periods progressed, the fresh weight loss was increased but did not exceed the maximum
permissible of fresh weight loss. The 28 kJ performed the highest firmness among the treatments. The UV-C
treatments demonstrated the less fungal incidence than control. The 28 kJ treatments exhibited the best visual quality,
firmness, titratable acidity and less fungal incidence among the treatments. So, ultraviolet (UV-C) irradiation reduced
postharvest fungal incidence of cherry tomato.
