What Happens as Eggs Age?
Eggs don’t instantly spoil after their expiration date, but their quality gradually declines.
As eggs get older:
-
They lose moisture and carbon dioxide
-
The egg whites become thinner
-
The yolks become more fragile
Older eggs may still be safe to eat, but fresh eggs taste better and perform better in cooking and baking—especially for dishes like omelets, poached eggs, or meringues.
How to Store Eggs Properly
After choosing fresh eggs, proper storage helps maintain their quality.
Follow these tips:
-
Keep eggs in their original carton to prevent odor absorption.
-
Store them in the coldest part of the refrigerator, not in the door where temperatures fluctuate.
-
Use eggs within three to five weeks of purchase for the best taste and texture.
How to Tell If an Egg Is Bad
If you’re unsure whether an egg is still fresh, you can try these simple tests.
The Float Test
Fill a bowl with water and gently place the egg inside.
-
Fresh eggs sink and lie flat at the bottom.
-
Slightly older eggs stand upright but remain submerged.
-
Bad eggs float, because air has built up inside the shell.
The Crack Test
Crack the egg into a separate bowl.
-
Fresh eggs have firm yolks and thick whites.
-
Older eggs have flatter yolks and runnier whites.
If the egg smells unpleasant or looks unusual, it’s best to throw it away.
