Hello my dear readers! Do you have unused raw eggs after the holidays? I stay quite often. After a while, I begin to doubt their freshness, and then the old tried and tested method of verification comes to my aid. Today I will tell you how to check the freshness of eggs in water.
I often buy homemade chicken eggs on the market, so it’s hard for me to control their shelf life. When they were laid chicken and how much they were stored before the sale is unknown to me. Housewives usually collect a batch and only then take it out for sale.
Comes to the aid of ordinary water and basic knowledge of physics. It is a pity to throw away the good, so you should tinker a little. Checking the freshness of raw chicken and quail eggs with water is very easy!
How to check the freshness of eggs in water in a proven way
We collect cold water in a bowl or glass.
If the egg has sunk to the bottom and "lay down" on its side, then you can be congratulated. You are dealing with the freshest, almost just demolished chicken specimen. In the photo - a glass on the left. If the test object falls to the bottom, but slightly lifts the blunt end up, then its age is about seven days. In the photo - on the right.
If the test subject drops to the bottom with a sharp end, and the blunt will look up, then he will be two to three weeks old. It should be used for cooking in the first place.
The freshness of quail eggs in the water is checked in the same way as the freshness of chicken!
Here in the picture check quail.
That's all! We learned to identify fresh eggs, dropping them into the water.
- Pour water with a bowl or clear glass.
- Dip a copy into the water.
- Watching his behavior: the egg on the bottom on the side is the freshest, slightly raised the blunt end - fresh, a week ago, stands perpendicular to the bottom with a blunt end up - two - three weeks old, has surfaced - is unfit for food!
I suggest you watch another video on how to check eggs for freshness.
On a note. Some housewives dissolve salt in the water before plunging the eggs in, explaining that the result will be more accurate. However, this is nothing more than a myth, and therefore it is pointless to spend a product without good.
Visual assessment of protein and yolk quality
Another way to check the freshness of a purchased product at home is to break it into a deep plate. It is advisable to use this method in cases where a raw egg is required during the cooking process.
The product in the bowl should be carefully considered. Fresh protein is transparent, with a jelly-like consistency. In this case, its lower layer will be thick, and the upper one - more liquid. In a long-stored product, this bundle is almost imperceptible.
The yolks of fresh eggs are bright, fluffy and bulging, and if the product is not fresh, they become flat.
Quality criteria for boiled eggs
Egg freshness can be determined not only when it is raw, but also after cooking. First of all it is worth paying attention to how the shell is removed. The harder this process goes, the less the "age" of the egg.
The second sign is smell. At all stages of freshness, eggs smell like sulfur, but if it is almost imperceptible to a recently torn-down product, then “amber” increases with time.
Peel the egg and evaluate the outgoing smell, it will need to be cut. Bad signs are watery, as well as the presence of mucus.
Attention! Often you can see on the edges of the yolk greenish, gray or bluish edging. This sign does not always indicate the deterioration of the product, the “bezel” may appear in cases when a fresh egg is simply digested.
Shelf life of eggs
Eggs can be stored in the refrigerator for 24 to 28 days after they have been torn down. At the same time, in the first week, the product is considered dietary, and later it is considered to be dining.
It is important to remember that even at the “dietary” stage, eggs are considered allergenic foods, and these properties only increase with time. For this reason, persons prone to similar reactions, as well as children and the elderly, should use this product only if its “age” does not exceed 7 days.
How to check the freshness of eggs at home?
At home, you can use the quick way, requiring plain or salted water. The popularity of this method due to the fact that nothing will have to be broken, and everything will remain safe and sound for future use. We list what is required in order to check eggs for freshness:
- An ordinary glass of water with a capacity of a quarter liter, filled with cold tap water,
- The product itself that needs to be tested,
- Information on how to check the freshness of eggs in water.
Dropping the product in a container with water, it will fall to the bottom and acquire a horizontal position. Does it determine that it is fresh or rotten? It is worth remembering forever - fresh!
When checking you ask the question, how does this method determine the deterioration of the egg? The fact is that the shell is tightly attached to the membrane, and if the product is fresh, it is characterized by the absence of air inside.
The expiration process of chicken eggs
This happens due to the penetration of air through the pores of the shell, which contributes to the detachment of the membrane from it, thereby inflating the air bag. A similar process occurs gradually during storage. Significantly reduces shelf life Product storage is improper and the temperature is high, causing bacteria to develop. If, dropping an egg in salted water, it floats on the surface, it is worth noting that it has already deteriorated.
Such a homely way will also help to know the degree of freshness, providing an additional reference point. This will give the hostess to understand the fresh product, or not, and where to let it go.
How to determine the freshness of eggs?
In the first week of their existence, they are considered dietary, and can be used in the preparation of dishes that are demanding to the shelf life. If the eggs take a horizontal position in the water, then there is no doubt that they are fresh. This product can be used for the preparation of any dishes.
Term from the week can be determined by looking at the same vertical position. However, this time the blunt end floats a little to the surface, but at the same time the sharp still touches the bottom. Such a term suggests that the product is only suitable for boiling it hard, or making an omelet. If a term is two weeks, scrambled eggs with an attractive appearance should not be expected, because the protein will fall flat on the pan, like a pancake.
Provided that the sharp end will not touch the bottom, remaining in the center with a blunt end on the surface, it is worth talking about a two-week shelf life. The egg is usable and cooked hard-boiled in ten minutes. You can also add it to salads. But there is a plus in this state of affairs: cleaning will occur much faster and will not be difficult.
If the egg test for freshness has ended up with a fully horizontal position, this indicates their corruption. They have already begun the process of decomposition, which indicates the impossibility to use this product in food.
Now the reader is aware of how to check the egg for freshness in water. To extend the periodshelf life It is recommended to do without washing before putting the product in the refrigerator, and to check for freshness just before use. After all, the egg shells are covered with pores, which maintain the shelf life, therefore, as soon as they come into contact with water, the protective sheath is washed off. Air penetrates faster, increasing the air sac, and the product deteriorates.
How to check a boiled egg for freshness
If the egg has already cooked, then you can check it by cleaning:
- Good, young is hard to clean. The shell is very tight to the shell, and when cleared together part of the cooked protein.
- If it is not the freshest, it will be very easy to clean.. She literally moves away from the protein along with the shell.
- If the egg is already rotten, a sharp, unpleasant odor will immediately appear when cleaning.which is impossible to confuse.
Buyers in stores are trying to take chicken eggs of the first category or selective, because they are larger. In terms of their usefulness, this is not entirely true.
After all, the largest carry old chickens, which are already becoming obsolete. Young animals carry more and more eggs, but they are noticeably smaller.
While the large eggs of the old hens contain more cholesterol, which is the main cause of heart and vascular diseases, and also leads to obesity.
Eggs of small sizes of the second and third categories are much cheaper.
Choosing eggs in the store, note:
- The surface of the shell should be smooth and without cracks.
- Choose eggs of young chickens - they are more useful.
- When you come home, use a glass of water to determine their freshness.
How to check the freshness of quail and other eggs?
Goose, duck, quail, chicken eggs have a limited shelf life, which is largely dependent on temperature.
The freshness of eggs depends entirely on the shelf life that must be observed. If they were stored in stores for too long, they are sold at a low price.
They may not be rotten or spoiled, but they definitely have a completely different structure.
The processes that occur in the egg do not stop, but only slow down when they are placed in the cold.
Waterfowl eggs are rarely used for food. More often they are left for reproduction of number.
The shelf life is determined by the storage conditions of the product. The cooler and richer the moisture environment - the longer the eggs retain freshness.
In order to save the raw egg, but without the shell, the remainder of the cooking. It must be placed in a clean container in a refrigerator.
From above, be sure to cover with a damp cloth or tightly close the lid. Unsealed eggs dry quickly. The yolk in this form can be stored in the refrigerator for one or two days. Protein - up to four to five days.
We check the quality of eggs with an ovoskop
Ovoskop is a device used since the most ancient times and is used to date to check the quality of eggs. This simple device is a flashlight with a directional beam of light.
You can check the eggs with an ovoscope at home. It is easy to make at home:
- This will require an ordinary flashlight or lamp.
- Place the flashlight in a light-tight box so that the light comes from above.
- At the top of the box you need to make a hole that will be smaller than the egg.
- Put the egg on this hole and carefully examine it.
A good quality young egg has a smooth surface and a smooth color without spots and blemishes.. Inside the eggs, which have been violated storage conditions, sometimes you can even see how the chicken is born.
This is noticeable from the bloody clots inside the shell and specific outlines. A rotten egg will have an unpleasant dull shade when it is x-rayed.
