Are Eggs Bad If They Sink Or Float

Are Eggs Bad If They Sink Or Float?

Eggs are a staple in many kitchens, and they can be used in a variety of dishes. However, one question that often arises is whether or not an egg is bad if it sinks or floats in water. The answer to this question is not as straightforward as one might think.

When an egg is fresh, it will typically sink to the bottom of a glass of water. This is because the air cell inside the egg is small, and the egg is denser than water. As an egg ages, the air cell will gradually get larger, and the egg will become less dense. This is because the egg's contents are slowly evaporating through the shell.

As the air cell gets larger, the egg will eventually reach a point where it is less dense than water. This is when the egg will start to float. A floating egg does not necessarily mean that the egg is bad, but it does indicate that the egg is not as fresh as it once was. However, the freshness of a not-so-fresh egg can be determined by cracking it open. If the yolk is still firm and the white is still thick, the egg is safe to eat.

There are a few exceptions to this rule. For example, some eggs may float even if they are fresh. This can happen if the egg has a very large air cell. Additionally, some eggs may sink even if they are not fresh. This can happen if the egg has a thick shell or if the egg has been boiled. It is safe to eat both kinds of egg.

So, to answer the original question, an egg is not necessarily bad if it sinks or floats in water. The best way to determine the freshness of an egg is to crack it open and examine the yolk and white.

Here are some additional tips for checking the freshness of eggs:

The float test: This is the most common way to check the freshness of an egg. Simply place the egg in a glass of water. If the egg sinks to the bottom and lays flat on its side, it is fresh. If the egg stands upright in the bottom of the glass, it is not as fresh but still safe to eat. If the egg floats, it is not fresh and should be discarded.
The smell test: Crack the egg open into a bowl. If the egg has a fresh, slightly eggy smell, it is safe to eat. If the egg has a sour or sulfurous smell, it is not fresh and should be discarded.
The yolk test: The yolk of a fresh egg will be firm and round. As an egg ages, the yolk will become flatter and less firm. If the yolk is very flat and runny, the egg is not fresh and should be discarded.

By following these simple tips, you can ensure that you are only eating fresh eggs.
