用二溴化乙烯(下称EDB)熏蒸处理柑桔类水果,以消灭地中海果蝇(Ceratitis capitata)和其他果蝇,这是根据几个进口这类水果的国家所制定的植物检疫法规定进行的一种处理方法,它对防治虫害的发生有显著的效果,但偶尔也发现熏蒸处理会损伤果实的表皮。美国农业部则采用了另一种处理方法,即将鲜果置于低温下贮藏,进行冷冻处理。要求柑桔类水果的果肉温度一般在进行冷冻处理后的2～4天内达到贮存规定,然后将果实在0℃下贮存10天或在2.2℃下贮存16天。然而,柑桔类水果,特别是葡萄和柠檬容易冻伤,冷冻处理会引起果实
Fumigation of citrus fruits with ethylene dibromide (EDB) to eliminate Ceratitis capitata and other fruit flies is regulated by the phytosanitary laws enacted by several countries importing such fruits A method of treatment, which has a significant effect on pest control, but occasionally found that fumigation will damage the fruit’s epidermis. The United States Department of Agriculture has adopted another approach, that is, fresh fruits placed in low temperature storage, freezing treatment. It is required that the temperature of the flesh of the citrus fruits is generally within 2 to 4 days after the freezing treatment is reached and then the fruits are stored at 0 ° C for 10 days or at 2.2 ° C for 16 days. However, citrus fruits, particularly grapes and lemons, are susceptible to frostbite, which can cause fruit
