o perform the floating water test, fill a bowl with enough water to completely submerge an egg. Gently place the egg in the water and observe its behavior. If the egg sinks to the bottom and lays flat on its side, it is very fresh. If it stands upright on the bottom, it is still safe to eat but should be used soon. If the egg floats to the surface, it is no longer fresh and should be discarded.
Why the Floating Water Test Works
The floating water test works because of the air cell inside the egg. As an egg ages, moisture and carbon dioxide escape through the porous shell, and air enters to replace them, increasing the size of the air cell. This makes the egg less dense and more buoyant. A fresh egg has a small air cell and will sink, while an older egg with a larger air cell will float.
Common Misconceptions About Egg Freshness
One common misconception is that a floating egg is always bad. While a floating egg is generally past its prime, it doesn’t necessarily mean it’s spoiled. However, it’s best to err on the side of caution and discard floating eggs. Another misconception is that eggs should always be refrigerated. While refrigeration extends shelf life, in many countries, eggs are stored at room temperature without issue due to different handling practices.
Additional Tips for Storing Eggs
To maximize the freshness of your eggs, store them in the refrigerator in their original carton. The carton helps protect the eggs from absorbing strong odors and flavors from other foods. Keep them in the coldest part of the fridge, not in the door, where temperatures fluctuate. Additionally, try to use eggs within three weeks of purchase for optimal freshness.
