Hebei reader Ms. Zhao asked: two days ago, my friend sent me a box of oranges, which could not be eaten in a short time. Some people say that oranges should be put in the refrigerator, while others say that oranges are fruits from the South and should not be put in the refrigerator. Some even say that oranges stored in refrigerators can cause poisoning. Which statement is correct?

Wang rikui, an associate researcher at the Citrus Research Institute of the Chinese Academy of Agricultural Sciences, replied: Although oranges are fruits of the south, if they can’t be eaten in a short time, it’s better to refrigerate them. Kumquat, tangerine, sugar orange, navel orange and other citrus fruits can be stored in the refrigerator. The temperature of the refrigerator is usually about 4 ℃. Under this temperature, the respiration of oranges is weak, so the consumption of nutrients is small. Moreover, oranges will not be frostbitten, and harmful substances will not be produced to cause food poisoning. In addition, the high humidity in the refrigerator can prevent the orange from losing too much water and make the taste worse. Generally speaking,


oranges can be stored in refrigerators for 2-3 months in Sichuan and Chongqing, while oranges transported to the north can be stored for about 1 month due to inevitable bumps during transportation. If oranges are stored indoors, the temperature is too high and the air is dry, the oranges are not only easy to lose water, but also more likely to rot. in this case, it is better not to store them for more than 2 weeks. ▲
