Eggs deserve special attention because if you eat them when they're bad, you're actually making yourself sick. Therefore, it is important to ensure that they are in the best condition before consuming them. If you're wondering if eggs you've been eating in the fridge for a while are still edible, check out these tips below.

How do I know if an egg has gone bad?

There are a few ways to tell if an egg is still good or if it's best to throw it away. For example, if you shake it and hear the yolk on the inside of the eggshell pop, it's still good. Here are some other tests.

Put the eggs in the water:

The first thing you'll want to do is place the eggs in a container filled with water, preferably transparent, so that you can see the results more easily. Keep these points in mind:

If the egg sinks quickly and stays in a horizontal position, the egg is still fresh.

If you see it slowly sinking and staying at the bottom in a diagonal or upright position, then the egg is not fresh.

You can think of it this way: the greater the angle, the older the egg. Still, this egg is edible.

If the egg does not sink to the bottom of the water, but floats in the middle, it is a sign that it has gone bad and should not be eaten.

If you see an egg floating on the water, it means that it has gone completely bad.

Floating is caused by the gases produced when organic matter breaks down. Like we said, the egg has crossed the line that it shouldn't eat right now.

Boiled eggs: If you boil the egg, cut it in half, and see that the yolk is in the middle and there is a small space filled with air, the egg is still delicious.

Cracked eggs: Another easy way to tell if the eggs are okay by placing them on a plate.

If you see that the egg is not spreading too much and the yolk remains intact, then the egg is fresh.

On the other hand, if you see the white and yolk spreading all over the plate or the yolk spreading completely, then you should consider that the egg has gone bad.

Look for an expiration date to determine if the eggs have gone bad:

What to remember is when the hen lays its eggs. This is known as "Week 0". From the third week, eggs should not be sold.

Depending on the date on the label, the eggs expire in the 4th week.

Since then, they begin to lose their organ function and should be consumed with caution from week 6 onwards.

Some good advice on keeping eggs good is to store them in their original cartons and always keep them in a cool, dry place.

They can stay perfect for up to three weeks.

If you cook the eggs, keep the leftovers in an airtight container. If kept this way, they can be eaten for 3 to 4 days. However, it's a good idea to check their smell, etc.

Remember, when the food is hot, the food will be kept at a lower temperature. In this case, it is better to keep them for only 2 days.

Eating spoiled eggs will cause great harm to people's health, especially the elderly, children, pregnant women and other people with poor systems, eating may cause poisoning. Therefore, it is important to learn to tell if eggs have gone bad. Especially in the hot summer, eggs are more likely to spoil than in other seasons.

So, how can you tell if an egg is good or bad?

How to tell if eggs are good or bad.

1. Knock it open directly.

Crack the shell of the egg directly, if the yolk is loose, the egg white and egg white are mixed together, or there is a rancid smell, it means that the egg has gone bad.

If the yolk is nearly spherical and slightly raised, and the egg whites (or whites) are only gathered around it, the egg is fresh. If the yolk is a little deflated and the egg white is transparent, but still clumped, the egg may be a little stale, but it is still edible. If the yolk is flat and the egg white is thin (almost like water), the egg is spoiled.

This is the most straightforward way to judge.

2. Float test.

Place the eggs in a basin of cold water at a water level about twice the height of the eggs. If the egg lies flat on the bottom of the water, it is very fresh, and the fresh egg will sink to the bottom of the bowl, and it may be on the side against the bottom of the bowl; However, if it is tilted or upright in the water, it means that it has been stored for a long time; Slightly stale eggs (which have been left for about a week) will also sink to the bottom of the bowl, but there will be a slight fluctuation up and down. And if it floats on the water, it means that the egg has gone bad, don't eat it.

Principle: The longer the egg is placed, the more moisture and carbon dioxide are lost in the egg, and the larger the air chamber in the eggshell. When the air chamber becomes larger, it is easier for the egg to float on the water, and when it shakes, it will make a swaying sound.

3. Shake to listen to the sound.

Put the egg between your fingers and shake it in your ear, and the fresh egg will not make a sound. Rotten eggs have the sound of slag, and the big ones have the sound of hollowing. The cracked egg has a crackling sound. The sound of water is the eggs that have been left for too long.

Tips: Many people will subconsciously shake the eggs when buying eggs to judge whether they are loose yolk eggs, which is a more common method. However, this method is actually not very certain, because even fresh eggs will make a sound under strong shaking.

It is recommended to cooperate with other identification methods for insurance purposes.

4. Sunlight observation.

Holding the egg in both hands like a tube, facing sunlight or light perspective, if the egg is reddish, translucent, and the yolk outline is clear, it is fresh; If it looks dull, opaque, or stained, the egg has gone bad.

If you peel the egg and smell a pungent smell, it means that the egg has gone bad.

How to make boiled eggs:

1. Wash the fresh eggs, soak them in a pot of water for one minute, and then bring to a boil over low heat. This is to prevent the eggshell from bursting during the boiling process.

2. After the eggs are boiled over low heat, then switch to warm heat and continue to cook for 3-7 minutes according to personal taste.

3. Hard-boiled eggs do not need to be taken out immediately, and then taken out after 1 2 minutes, or put in cold boiled water or cold water to cool down for half a minute, so that they are easy to peel.

Crafting tips. 1. Soak in water.

Before boiling eggs, it is best to soak them in cold water for a while. At the beginning of cooking, the water must be submerged over the eggs, otherwise the boiled eggs will not only be unevenly cooked, which will affect the taste, but the yolk will also move out of the egg core and move to the eggshell. Soak the eggs in cold water for a while to reduce the air pressure inside the eggs; Then put it in a pot of cold water and boil so that the eggshell is not easy to break.

2. Firepower. If high heat is used when boiling eggs, it is easy to cause the air in the eggshell to expand sharply and cause the eggshell to burst; If you use low heat, it will prolong the time of boiling eggs, and it is not easy to grasp the age and tenderness of good eggs. Practice has proved that boiled eggs are most suitable over medium heat.

After the hard-boiled eggs deteriorate, the appearance will not change significantly, but after knocking the skin open, there will be a noticeable feeling, sometimes you will smell a pungent smell, sometimes you will feel particularly sticky, when eating, you will also feel some peculiar smell, if there are these conditions, it is recommended that you stop eating.

Summary. You can also put the eggs in a basin full of water, if the eggs sink in the water, they are fresh eggs, and the floating eggs are bad. This is because fresh eggs have a larger specific gravity than water, so they will sink when placed in water.

When the egg is broken, the protein inside will produce gases such as ammonia and hydrogen sulfide, and if there is gas in the eggshell, the specific gravity of the egg will be smaller than that of water, so it will float when placed in water.
