How to tell if eggs are bad

How to judge whether eggs have gone bad is a question for many housewives. A widely circulated method on the Internet is to place eggs in water and judge whether the eggs have gone bad by whether they settle. So is this method scientific? Today we will specifically explore the credibility of this method and see how to judge whether eggs have gone bad.

How to tell if eggs are bad

1. How to judge whether eggs are spoiled

The popular method on the Internet is to put the eggs in water. If they float, then the eggs are spoiled. If they can settle to the bottom of the water, then they are fresh eggs. In fact, this method can indeed detect whether the eggs are spoiled, that is, the method of detecting spoilage by egg sedimentation is scientific and credible.

2. The principle of judging the deterioration of eggs in water

Because the eggshell is breathable, air can flow in and out. If the eggs are stored for a long time, more air will enter the eggs, and the eggs will become clearer, causing the eggs to float on the water or rise. If they are fresh, the eggs will sink into the water. When there is too much air in the eggs, the water in the eggs will overflow, and it is easy to produce microorganisms and enzymes, causing them to deteriorate.

3. Other ways to judge whether eggs are spoiled

Although the above method can determine whether eggs have gone bad, it is not recommended because if you put eggs in water to test the freshness of eggs, it is easy for bacteria in the water to enter the eggs, which will cause the eggs to go bad faster after being put into water and make them difficult to preserve. Therefore, when selecting eggs, you should still observe the appearance. Eggs with a rough appearance or even white spots are fresh eggs.
