1, refrigerator storage: If there are many boiled eggs that can't be eaten in a short time, they can be stored in the refrigerator, but be careful to separate them from other foods. If possible, you can also pump the air clean and store them in vacuum.

2, salt water preservation: if there is no refrigerator at home, you can put eggs in high-concentration salt water, one can isolate the air, and the other is that many fungi are not easy to survive in salt water.
