Citrus fruits such as kumquat, orange, sugar orange and navel orange can be kept in the refrigerator. The temperature of the freezer is about 4℃. At this temperature, oranges have weak respiration, so they consume less nutrients, and oranges will not be frostbitten, nor will they produce harmful substances to cause food poisoning. In addition, the humidity in the refrigerator is high, which can prevent oranges from losing too much water and making their taste worse.
