Is it bad for an egg to float up in the water?

Yes. If the raw egg floats in the water, it means that it is broken. Because the bad eggs are left for too long, on the one hand, the protein in it is rotten and will produce a lot of gas.

On the other hand, part of the water in the egg will evaporate from the small holes of the eggshell, and the gas will evaporate, and the weight of the egg will naturally become lighter, and the specific gravity will also decrease, so it will float on the surface of the water.

How to tell if raw eggs are good or bad.

1. First of all, we look at the appearance of the egg, if there is a layer of hoarfrost, and the surface of the egg is not very smooth when touched by hand, it is more black and astringent, which means that the egg is an old egg, not fresh.

2. Pinch the egg with your hand and shake it next to your ear, there is no sound of water is a fresh egg, on the contrary, there is a sound of water is a bad egg, and the louder the sound of water, the greater the degree of rot of the egg.

The eggs are not fresh anymore.

Fresh eggs lie on the bottom of the water, and those that are more than 3 weeks old float in the water.

According to industry insiders, after the hard-boiled eggs are peeled, the public will find that there is an air chamber at the end of the egg. Generally, the older the "age" of the egg, the larger the air chamber, the more air in the egg, and the greater the buoyancy, so the more stale the egg, the more it will float on the water.

However, the storage time of the eggs does not necessarily indicate the freshness of the eggs, for example, a fresh egg from the same farm outside the island accidentally bumped into the bottom of the bowl during the experiment, causing a slight crack, after the bumps in the vehicle and the high temperature, by the time the experiment was done in the afternoon, the egg that should have sunk to the bottom became able to stand. It is foreseeable that if it is left for another day, it may be suspended in the water.

That is to say, the "blind selection" of the "boiled women" in the market, when they see the eggs "standing" in the water, they should mutter, this kind of eggs may be intact, just a little longer eggs, but it may also be "egg age" is not long, the freshness is discounted.

If the egg is left in drier air for too long, for example, for more than a month, the liquid in the egg will evaporate, the weight will be reduced, the density will be reduced, and the egg will float. But that doesn't have to be broken. Criteria for eggs to go bad:

The egg white is severely thinned, the yolk is dehydrated and solid, the color turns black, and the smell becomes stinky. If it is only lightweight, the egg white concentration is not very thin, the smell is normal, and it is still edible, but it must be heated and cooked.

An egg that floats in water is bad, and if it just stands upright in the water and can't float completely, then the egg is not fresh and is about to spoil. We usually keep the egg refrigerated and do not let it come into contact with too much moisture, so that it is not easy to spoil. Eggs that can float in the water are not broken.

Eggs are a very nutritious food, and many people like to consume it for breakfast. Normally the eggs will sink to the bottom of the water, but sometimes we will encounter the situation of eggs floating on the water, what is going on? If the eggs in our house can float on the water, it means that the eggs have gone bad.

If the eggs in our house stand upright in the water but cannot float completely, it means that the eggs are not fresh and are about to spoil. When we usually store eggs, we can put them in the refrigerator and try to avoid letting them come into contact with too much water, so that the eggs are not easy to deteriorate.

In general, eggs sink to the bottom in water. If it floats on the water, the eggs are not fresh. It doesn't have to be broken. Eggs will float on the surface of the water even if they have a dry cough. You can open it and try it. If it's broken, don't eat it.

Hello friend, if the egg floats in the water, it is not necessarily bad, the egg should be able to float in the water, if it is a broken egg should not float in the water, it will sink.

Yes, even if it's not bad, it's not fresh anymore, so don't eat it!

The egg can float in the water because edible salt is added to the water, which causes the density of the water to increase, giving the egg an upward force, so it causes the egg to float in the salt water. When the egg is placed in salt water, the buoyancy force will be greater than the gravitational force, and the resulting force will go upward, causing the egg to float.

Eggs floating up are not necessarily bad, eggs are placed in drier air for a long time, such as more than 1 month, the liquid in the egg will evaporate, the weight is light, resulting in a smaller density, so it will float, but it is not necessarily broken, the bad standard is that the egg white is seriously thinned, the yolk is dehydrated and solid, the color becomes black, and the smell becomes smelly. However, if it is only light in weight, the egg white concentration is not very thin, and the smell is normal, it can still be eaten, but it must be heated.

If there is a layer of hoarfrost, and the surface of the egg is not very smooth when touched by hand, it is more black and astringent, which means that the egg is an old egg, not fresh.

Summary. Hello dear, I'm glad to answer for you, because the protein in the bad egg is destroyed, and a lot of gas is produced, and after the moisture and gas are discharged, the egg will float when it becomes lighter.

Dear to you, the scum is good, I am happy to answer for you, because the protein in the bad egg is destroyed, and a lot of gas is produced, and the moisture and gas are discharged for the first time, and the egg will become lighter, and the beam will tremble.

If you put the eggs in the water, the fresh eggs will easily sink to the bottom of the water, while the bad eggs will float back to the surface. This is because fresh eggs have less air in them and are heavier; If the egg is left for a long time, some of the moisture inside will run out of the small holes in the eggshell, and the bacteria on the outside will also run in from the small holes in the eggshell of the Yishizao stove and make the eggs spoil. At this time, the egg whites start to smell and produce a lot of gases, which will continue to evaporate.

Water and gas are scrambling to get out of the eggshell, and the weight of the egg is much lighter, so if you put the bad egg in the water, it will float.
