If you have boiled and peeled an egg and then refrigerated it overnight, several things can happen:
Cooling and solidification: As the boiled egg is placed in the refrigerator, it cools down rapidly. The proteins in the egg white will solidify, giving it a firmer texture compared to when it was freshly boiled.
Loss of moisture: Eggs have a natural protective coating called the cuticle or bloom, which helps retain moisture and keep the egg fresh. When you peel the egg, this protective coating is removed, making the egg more susceptible to moisture loss. If not stored properly, the egg may dry out slightly in the refrigerator.
Odor absorption: Eggs have a porous shell, and when they are peeled, the exposed inner surface can absorb odors from other foods in the refrigerator. To avoid this, it's best to store the peeled eggs in a covered container.
Flavors can meld: The peeled boiled egg may also absorb flavors from other foods in the refrigerator if it is not stored in an airtight container. This could alter the taste of the egg slightly.
Safety concerns: When storing boiled eggs in the refrigerator, it's essential to maintain proper food safety practices. Cooked eggs should be kept in the refrigerator at 40°F (4°C) or below to prevent the growth of harmful bacteria.
Overall, if you store the peeled boiled egg correctly in an airtight container and at the appropriate temperature, it should remain safe to eat and relatively fresh for a day or two. However, as time goes on, the texture and flavor may change, and the egg could become less enjoyable to eat. It's always a good idea to consume refrigerated boiled eggs within a few days for the best taste and quality.
