How to tell if eggs are fresh: some home tricks to check the freshness of the product we are about to consume.
Eggs are a very healthy food that should be consumed quite frequently to bring all of its benefits to our body.
Although eggs can last for a while, it is best to buy them fresh and consume them as soon as possible to make the most of their properties.
Treatments to keep eggs fresh
The freshest and most quality eggs are obviously those that can be bought directly from the farms. Although eggs are easy to find at the supermarket, they are usually not as fresh as they seem. Industries subject them to some treatments to prolong their freshness and keep them on the market longer.
For example, some eggs are partially frozen and stored in a cold environment for weeks before the company takes them to the store or supermarket to be sold.
Some tricks to tell if the eggs breast fresh
Although “old” eggs can still be eaten, they don't taste the same as fresh eggs. And when we prepare them, they are not as perfect as we hope. But how to tell if the eggs are really fresh?
In the United States and other parts of the world, the egg industry prints a series of numbers from 000 to 365 on the egg carton. This is the Julian date or Julian day and indicates when the eggs are cleaned and packed in the cardboard egg cup.
For example, if the number 000 is printed on the carton, it means that the eggs are from January 1st, if there is the number 213, it means that they were packed on August 2nd.
This date is accompanied by another number indicating the expiry date, that is the time limit within which the eggs can be sold to the consumer. For example, if an egg carton has the number 015 February 28, it means that the eggs are January 15 and can be sold until February 28, which is a month and a half later.
Who would want to buy six week old eggs when they could have fresh eggs? Certainly none.
Evidence of egg buoyancy
Often we do not have the cardboard packaging available to check the freshness of the eggs through the date. There is, however, an alternative that can help us understand how fresh the egg we are about to eat is.
The test consists in putting an egg in a cup of water, being careful not to break it. If the egg is fresh, it will sink and arrange itself lengthwise in the lower part of the cup.
The older the egg, the more it will float in the water. This is because, with the passage of time, the egg loses water through the pores of its shell. Which causes a decrease in its weight and an increase in the air inside.
Why is it so important to consume fresh eggs?
As with any other food, the fresher the eggs, the more nutritious and flavorful they will be. However, when it comes to buying eggs, many people can get confused because they may seem like it, when in fact they have been subjected to cold storage techniques.
The results are seen at home when they are prepared. They don't have the same taste or color as fresh eggs. Fresh eggs always have a more pleasant taste. Furthermore, the color of the yolk is darker and the egg white easily separates from the yolk without the two parts being mixed.
The egg contains carbonic acid dissolved in the egg white and yolk. Over time, the acid escapes in the form of gas through the pores of the shell, causing an increase in pH and a series of effects such as:
- Loss of egg consistency
- The yolk moves from the center of the egg.
- It increases the repulsion force between the proteins of the egg white which loses color over time.
Is it recommended to wash the eggs?
Under no circumstances is it recommended to wash the eggs because there is a risk of weakening or damaging the shell that acts as a protective barrier and prevents the entry of microorganisms.
If the eggs are washed, the cuticle that adheres to the shell weakens and prevents bacteria from entering the egg. Consequently, washing the eggs and then consuming them could increase the risk of being affected by some microorganism.
