Abstract

短波紫外線(UV-C)是指波長低於280nm 之紫外線，以低劑量UV-C 照射處理來減少園產品的採收後腐爛的發生，是近年來正在研究中的一種非化學性的處理技術。已知包括洋蔥、甘藷、柑桔、蘋果、桃子、甜椒、胡蘿蔔、番茄、葡萄、草莓等重要園藝作物都可以經由UV-C 照射處理而減少採收後腐爛，延長櫥架壽命。UV-C 照射處理的可能作用機制包括直接殺死病原菌、誘導植物體產生抗病性以及延緩果實的後熟。UV-C 照射處理的效果受到照射劑量、產品種類、發育成熟度、貯藏溫度及有無照光等多種因子的影響。UV-C 照射處理技術目前仍在試驗階段，仍有困難需要克服。但是由於UV-C 照射處理可增加採後園產品的抗菌能力，一方面可減少貯藏及運銷時腐爛的發生率，另一方面能取代或減少採後殺菌劑的使用，因此是一種值得做進一步研究之採後處理技術。 Shortwave ultraviolet radiation (UV-C) is the part of ultraviolet radiation with wavelength less than 280 nm. The application of low dosage UV-C irradiation to reduce postharvest decay of horticultural products has been a non-chemical postharvest technique developed during the past twenty years. So far, UV-C irradiation has been shown to be able to extend the postharvest life of a number of important horticultural products, including onions, sweetpotatoes, citrus fruits, apples, peaches, bell peppers, carrots, tomatoes, grapes and strawberries. The possible mechanisms of UV-C irradiation include direct germicidal effect, induced resistance in treated products and delay fruit ripening. The efficacy of UV-C irradiation is affected by a number of factors, including irradiation dosage, kind of products, development stages, storage temperature and presence of light. Currently, the UV-C irradiation technology is still under testing and there are obstacles to be overcome. However, since the UV-C treatment can enhance the disease resistance in harvested products; it has the potential of reducing the postharvest decay incidence during storage and marketing period as well as reducing the utilization of fungicides. Further studies in the development of UV-C irradiation technology should be encouraged.
