Using an on-line UV-C apparatus to treat harvested fruit for controlling postharvest decay.

An apparatus was designed to deliver low-dose UV-C light to the surface of fruits 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 fruits. The dosage of the UV-C light delivered to the fruit surface was regulated by varying the speed of the conveyor belt. Postharvest decay (caused primarily by Botrytis cinerea and Penicillium expansum) after 28 days' storage of Empire apples at 18 deg C was reduced by 52% relative to untreated controls when the fruits were conveyed at 6.2 m/min (1.38 kJ/m2 dose) under the UV-C apparatus. Factors affecting the practical application of UV-C irradiation of fruits for controlling postharvest decay are discussed.
