How to preserve oranges

　　1. Pack it in a fresh-keeping bag and keep it out of contact with air for a longer time. But be sure not to keep it fresh in the refrigerator, as this will speed up rot.

　　2. Find some baking soda (not too much), dissolve it in water, wash the oranges one by one with soda water, take out the oranges and let them dry naturally, so that the soda water forms a protective film on the outside of the oranges, and then put them in a plastic bag.

　　Finally, seal the bag. It must be sealed. Never allow air to enter the bag. In this way, the storage of oranges will be extended for a long time. There is no problem in keeping them for three months.
