Oranges are one of the fruits we eat most often, because the pulp of oranges is thick and juicy, and the juice is also rich.
And oranges are not expensive, cheap and good. So some people will buy a lot to eat at home, but sometimes we can't finish it if we buy too much, and we are afraid it will go bad if we keep it.
Why don't oranges rot after a long time?
In fact, oranges last longer than other fruits because they are wrapped in a leather bag.
Experiments show that the longest shelf life of navel orange can reach a long time, and it can also reach 3-5 months in our daily life.
But oranges should not be exposed to the sun or frozen, because the weather in the south is not cold, so it is best to keep them in the refrigerator.
It's cold in the north, so it's not suitable for outdoor. But oranges had better be fresh, so they will taste and taste good.
First, how to keep oranges fresh?
We can buy some baking soda and dissolve it in water. Wash the oranges one by one with soda water, and then take them out to dry naturally. In this way, soda water will form a protective film on the outside of the orange, and then put it into a plastic bag after the orange dries.
Finally, we just need to seal the opening of the plastic bag and don't let air into the bag, so the storage time of oranges will be much longer.
Generally, it is no problem to put it on for three months. When one day we want to eat, we can take it out. And this method is very simple, you can try it.
Preservation conditions of oranges
Under normal circumstances, the temperature of refrigeration in the refrigerator is around 4℃, and at this temperature, the respiration of oranges is relatively weak.
Therefore, the consumption of nutrients is relatively small, so oranges will not be frostbitten, and the humidity of the refrigerator is relatively humid, which can prevent oranges from losing too much water and making their taste worse.
Tips for citrus preservation
The optimum storage temperature of citrus is 5℃- 10℃. When we store oranges, we'd better leave a distance for each orange and put it in a ventilated and cool place.
But if you leave it in the refrigerator for a long time, if you find signs of mildew, you should throw away the moldy oranges as soon as possible, otherwise it will easily pollute other oranges.
