Eggs are often sold at room temperature at supermarkets.However, after purchasing eggs, isn't it basically stored in a refrigerator instead of room temperature?In supermarkets, the flow of refrigerated storage is common after buying at room temperature, but I am worried about what the difference is.

This time, I will tell you why eggs are sold at room temperature, appropriate storage methods, and how long the expiration date will be.

■ Reasons for eggs are sold at room temperature. The reason why eggs are sold at room temperature is to prevent condensation.It is important that eggs do not change as much as possible.

Here, what happens if the eggs are stored at room temperature, and if they are sold in refrigerated?I will answer the question.

As I have already mentioned, eggs are sold at room temperature to prevent condensation.Condensation is, for example, if you put a cold plastic bottle out in a hot season, for example, you will get water droplets around it.That is the state of condensation.

In other words, condensation causes water droplets on the egg surface.So why shouldn't the surface of the egg be attached to the surface of the egg?In fact, the eggs have a lot of small holes that people cannot see.

Then, if a water drops on the surface of the egg due to condensation, germs will enter from the small hole.Therefore, it is sold at room temperature to prevent the temperature change as much as possible.

卵が、常温ではなく、もし冷蔵で売られていた場合はどうなるのか、気になりますよね。実は、卵が冷蔵で売られていた場合は、卵の劣化が早まる可能性があります。

This is because if the eggs are sold in the refrigerator, the storage temperature will change multiple times.Eggs are born from chickens, packed in packs, and are purchased after being displayed in supermarkets.

In other words, if the eggs are sold at room temperature, there is no major temperature change from the birth of the eggs to the purchase and put in the refrigerator.However, if the eggs are sold in refrigerated instead of room temperature, the temperature changes once displayed, and the temperature changes to the room temperature after purchasing it, and the temperature changes.The number of times will increase.

As the number of times the temperature changes increases, the possibility of condensation increases and may deteriorate.

■ Which egg is better for eggs at room temperature or refrigerated?

When storing eggs, it is important not to change the temperature as much as possible to prevent condensation.So, is the preservation at home suitable for preservation at room temperature or refrigerated?

Here, we will tell you how to preserve the eggs and the precautions when saving.

卵の保存方法は、結論をいうと、常温でも冷蔵でもどちらでもOKです。ただし、卵の表面に結露が生じないように、温度変化には十分に気をつける必要があります。

For example, if you buy eggs sold in refrigerated in supermarkets at room temperature after buying them, the temperature changes will increase accordingly.Therefore, if the eggs are sold in refrigerated, it is important to store them quickly after buying them.

In addition, there is no major temperature change, such as frequently returning eggs from refrigerated storage to room temperature, or keeping refrigerated from room temperature.

I mentioned that the preservation of the eggs is good at room temperature or refrigerated, but there is one precaution.It is food poisoning by Salmonella.

Salmonella is well known as a bacterium that causes food poisoning.It is said that Salmonella may be attached to the egg shell, but the eggs that are currently sold are often well -washed, so they are rarely attached.

That said, it doesn't mean that Salmonella's bacteria are not 100%.Therefore, it is important to take measures to prevent bacteria from proliferating and take measures against food poisoning, considering that Salmonella is attached to the egg.

Specifically, it is important to store eggs and cook heat at 10 ° C or less.

If you are not sure how to save the eggs, make sure to store it refrigerated.In fact, the Ministry of Health, Labor and Welfare's website recommends that the eggs after purchasing should be refrigerated.

The main reason why egg refrigerated is recommended is that, as mentioned above, there is a risk of food poisoning.Especially in the spring, summer, and autumn seasons, it often costs more than 10 ° C at room temperature.

Saving eggs in the refrigerator (10 ° C or less) can prevent the growth of Salmonella.However, even if you put it in a refrigerator instead of room temperature, if Salmonella is attached, the bacteria will not disappear completely.Therefore, it is important to cook, such as when you eat eggs, especially if you are at a high risk of food poisoning, such as children and the elderly.

■ Estimated expiration date when storing eggs at room temperature

Eggs can be stored at room temperature.So, I'm curious how the shelf life is when storing at room temperature.The expiration date when storing eggs at room temperature varies depending on the season.

Here, let's look at how long the eggs can be stored when storing the eggs by each season.

If the eggs are stored at room temperature in spring or autumn, basically three weeks should be a guide for the expiration date.By the way, the last three weeks are not after purchasing eggs, but after eggs are spawned.

The average temperature in spring and autumn is 20-23 ° C.Therefore, it can be stored relatively long at room temperature compared to summer.However, considering food poisoning by Salmonella, it would be nice to be able to store it in an environment of 10 ° C or less, such as in a refrigerator.

If you want to store eggs at room temperature in the hot summer season, eat at most two weeks.The two weeks here are the time since the eggs were spawned.

In addition, the temperature in summer is mostly over 30 ° C.Therefore, it is necessary to pay more attention to food poisoning rather than storing at room temperature in spring or autumn.If you want to store at room temperature in summer, do not eat eggs raw, but eat it through fire.

If you want to store eggs at room temperature in relatively cold season, such as in winter, use it for about one and a half to two months after spawning.In winter, the temperature is often less than 10 ° C, so it can be stored relatively long at room temperature.

In general, the expiration date of the eggs is two weeks from the date of packing throughout the year.The expiration date of the last two weeks is assumed that it is stored at room temperature, but even so, it is worried about food poisoning in hot weather such as summer.Therefore, instead of storing eggs at room temperature, make good use of the refrigerator to maximize the risk of food poisoning.

■ Proper way to preserve eggs

The basics of eggs after purchasing are to store refrigerated.If the eggs are stored at room temperature, as mentioned above, the risk of food poisoning will increase.

From now on, I will tell you about the appropriate storage methods to make the egg fresh longer.

卵を購入したら、できるだけ早く冷蔵庫へ。サルモネラ菌の増殖を防ぐため、どれだけ早く冷蔵庫に入れられるかがポイントになります。

I mentioned that it is important to eliminate the temperature difference as much as possible to maintain the freshness of the eggs, but now many supermarkets sell eggs by refrigeration.Then, after purchasing the egg, the temperature difference when it changes from refrigerated storage to room temperature is large.If you can't help buying it at a supermarket to getting home, try to return it quickly to refrigeration.

In addition, even if the eggs are sold at room temperature, it is safer to save them in the refrigerator that can stably create an environment of 10 ° C or less.

It is important to eat eggs within the displayed expiration date.As I mentioned above, the expiration date of the eggs is basically set for two weeks after packing.

In addition, the expiration date of the eggs is set as a period that can be eaten raw, but depending on the preserved environment, there is no need to worry about food poisoning.

Therefore, it is important to use the eggs within the expiration date, of course, but if the deadline is close, try to cook, such as boiling or baking.

When storing eggs refrigerated, make sure that the temperature in the refrigerator is 10 ° C or less.If the eggs have Salmonella bacteria, if they are not preserved at 10 ° C or less, bacteria may explode.

Even if the egg is put in the refrigerator, if the temperature inside is set to 10 ° C or higher, it will be the same environment as storing at room temperature.To reduce the risk of food poisoning, check again to see if the temperature in the refrigerator is 10 ° C or less.

■ Precautions when saving eggs [room temperature / refrigerated]

卵のベストな保存方法を解説卵は常温で売られているけど自宅では冷蔵でいい？適切な保存方法を解説！

Eggs can be stored at room temperature and refrigerated.However, I told you that refrigerated storage is recommended in consideration of food poisoning.However, in fact, it is necessary to pay attention not only to the environment but also to other detailed precautions to save eggs properly.

Here, I will tell you in detail about the six precautions when saving eggs.

卵を冷蔵保存するときは、冷蔵庫のドアポケットに置くことが多いのではないでしょうか。冷蔵庫の設計自体、ドアポケットに卵フォルダーがあることも多いでしょう。

However, storing eggs in the door pocket is not a recommended storage method.This is because the door pocket is easily transmitted by opening and closing the refrigerator, and the temperature changes drastically.

While storing the eggs in the door pocket and repeating the refrigerator, repeating the refrigerator, the vibration may crack the eggs.In addition, the door pocket is a place where the temperature changes drastically compared to the back of the refrigerator.As mentioned above, the eggs are very vulnerable to temperature changes, so be sure to store them in the back of the refrigerator as much as possible.

Whether you store eggs at room temperature or in a refrigerator, replace them with an egg -only folder is not recommended.You might think, "Why can't you recommend it, but you can't recommend it!?", But the reason is that the eggs become naked.

Normally, eggs are put in a pack at the time of purchase, making it difficult to crack even if there is some vibration.Egg packs also have a role in reducing the possibility of germs into the inside.Therefore, even though it is an egg -only folder, it is not an appropriate storage method to remove the egg from the pack.

When storing the eggs, make sure you turn the eggs downward.

As a major premise, egg yolks float when the eggs become older after spawning.Therefore, it is important to keep the egg yolk as possible as much as possible when the egg yolks float over time.

And those who do not have eggs have a place where the air of temperament is accumulated.In other words, saving the eggs on the egg down will reduce the possibility of touching the shell even if the egg yolk floats.

Don't wash the eggs before storing them.If the surface of the egg is dirty, you will want to wash the eggs, but if you wash the eggs, it will be easier for germs to enter.

On the surface of the egg, there is a thin membrane called the bacteria that prevent various bacteria from entering.If you wash the eggs, the layer will flow.Therefore, save the eggs as they are purchased.

I guess there is only one experience of "I broke the eggs ...".Or, if you break the eggs too much, you'll want to save them in their split state.

However, please refrain from storing the egg with the cracked state.Because once the egg is divided, the contents will be exposed.Because the contents are exposed, of course, it is not possible to guard the germs with the shell, making it easier to enter.

The risk of food poisoning will increase, so use up the eggs that have been broken once as soon as possible.

Storing eggs is basically not possible.If the egg with a shell is stored, the contents may expand and break.

On the other hand, even if the egg is broken once and stored, as mentioned above, it will be easier for various bacteria to enter.Also, even if the eggs are properly frozen and stored and thawed, the egg yolk will not return from the frozen state.

Even if the eggs can be frozen and stored, it will be difficult to handle.Eggs should be stored at room temperature or if possible if possible.

■ How to distinguish fresh eggs

So far, we have talked about the appropriate storage method of eggs.It turns out that the purchased eggs are basically important to store refrigerated, and the expiration date is set for two weeks after packing.

From now on, I will tell you how to distinguish the fresh egg when purchasing an egg at a supermarket.

卵を購入する際は、賞味期限だけでなく、排卵日付も見るようにしましょう。排卵日付は、その名前のとおり排卵された日を表しているため、日付が遅い方が新鮮な卵だと分かりますね。

The ovulation date is listed on the surface of the egg pack or a sticker on each egg.When buying eggs, please be careful not only on the expiration date, but also on the ovulation date together.

卵は、表面がツルツルしているよりも、ザラザラしている方が新鮮な証拠です。上記で、卵の表面にはクチクラ層という、雑菌が入り込むのを防いでくれる膜があることをお伝えしました。

If there is a well -laid -up layer, the surface of the egg is rough, but the slippery egg has almost no membrane.At first glance, it seems that smooth eggs are fresher, but look at the eggs in the pack and choose something rough.

Fresh eggs are characterized by sinking when floating in water.There is a small hole on the surface of the egg, so it takes time to save, and if the eggs of the egg come off from the hole, it floats in the water.

How long will it be stored, will the moisture escape from the eggs? It depends on the preserved environment such as room temperature and refrigerated, and there is no clear answer.However, it is not possible to prevent the moisture gradually removing in both the room temperature and refrigerated method, so I want to eat as soon as possible.

It is difficult to do this when purchasing this way, because it is necessary to put out the egg from the pack, but please try it once at home.

■ How to distinguish the worse eggs

We have introduced how to distinguish the freshness of eggs.So, on the contrary to freshness, do you know what it looks like if the egg gets worse?

Here, I will tell you how to distinguish when the egg gets worse.

If the yolk collapses together when the egg is broken, the eggs may be worse.Eggs lose their original hardness as time goes older.

If you are worried that the old eggs are getting worse, let's divide into a flat plate.If the yolk collapses or the white is too wide, it is evidence that the egg is old.

If you check this state when you break the egg, instead of eating it raw, heat cooking, such as omelet, to prevent food poisoning firmly.

As mentioned that fresh eggs sink when immersed in water, the worse eggs float on the water.

The eggs will come off as the eggs go through as the storage time goes on, but instead of the air.In other words, the older the eggs become older and worse, the more air in the eggs.As a result, the eggs that contain a lot of air float in water.

Shake the egg up and down, and when the sound is leaking from inside, the freshness of the egg is reduced.

The worse eggs said that air would enter inside and float when soaked in water.For the same reason, if air enters inside the egg, the gap will increase.Because of the large gap, when the egg is shaken, the contents hitting the shell and sounding.

With this way of distinguishing, you can identify the freshness without breaking the eggs.If you hear a sound from an egg, boil it through the fire, such as boiling.

After buying an egg, you may have noticed that the eggs were cracked ...?

In such a situation, the cracked eggs may be worse.Bacteria are easier to get into the cracks of the shell.

Also, if you do not know how much time has passed since the cracks entered, many germs may be growing inside.Therefore, if you notice the cracks of the eggs, first put them in the refrigerator instead of the room temperature and heat them sufficiently.

■ Eggs should be stored refrigerated instead of room temperature and eat deliciously!

This time, we talked about why eggs are sold at room temperature and how to save eggs properly.If the eggs are stored at room temperature at home, what is the expiration date?You can understand that the answer is different for each season.

How often should an air purifier be attached?
