Abstract:

All apparatus was designed to deliver low-dose UV-C light to the surface of fruit on a processing line and tested for its control of postharvest decay. It consisted of a row of UV-C emitting lamps mounted on a frame above a conveyer belt that transported the fruit. The dosage of the UV-C light delivered to the fruit surface Was regulated by varying the speed of the conveyor belt. Postharvest decay after 28 days storage of 'Empire' apples was reduced 52% relative to the untreated checks when the fruit were conveyed at 6.2 m · min-1 (1.38 kJ · m-2 dose) under the UV-C apparatus; Factors affecting the practical application of UV-C irradiation of fruit for controlling postharvest decay are discussed.
