Comment tester si vos œufs sont frais ?

Eggs are high in protein and rich in nutrients. The most commonly used food in the cooking process, whether eggs need to be cleaned, is a concern of many people. Unwashed eggs can have many hazards.

Réglementations locales concernant les œufs

Many countries have clear regulations. The U.S. government stipulates that eggs sold in supermarkets must be washed; eggs are sold under refrigeration to extend the "fresh period" of eggs. This kind of regulation exists in many countries and has become a trend. Therefore, it is necessary to purchase an egg washing machine to operate the egg industry, as well as other supporting equipment, egg grader, and egg inkjet printers.

Comment tester si un œuf est frais ?

Type one： The bigger the spread and the more irregular the edges, the more stale the egg will be. Normally, there will be a thin film between the egg yolk and the egg white, which is called "yolk film" professionally. As the storage time becomes longer, the elasticity of the egg yolk film will become smaller and smaller, or even rupture.

And the egg yolk will melt together. The more intuitive result is that when an egg is knocked open, the yolk will spread out immediately, there is no feeling of being "wrapped", and it is very casual.

Type two: Look at the size of the air chamber, the larger the air chamber, the less fresh the eggs will be. Where is the air chamber? When peeling eggs, you often see a dent on the side of the big end of the egg, right? That is the "air chamber" of the egg. From the moment the egg is born, its weight begins to change, generally becoming lighter and lighter.

This is because there are pores in the eggshell, which will allow the moisture in the egg to evaporate continuously, and the weight of the egg will gradually decrease. Yes, the egg baby is still a breathing egg after leaving the mother chicken's body! But the longer it breathes, the less water it has and the less fresh it becomes.

La chambre à air d'un œuf fraîchement pondu ne dépasse pas 3 mm. Si la chambre à air de votre œuf est significativement plus grande que cela, la fraîcheur sera inférieure. Bien sûr, une température et une humidité de stockage inappropriées accéléreront la perte de poids des œufs.

Comment stocker correctement les œufs ?

Les œufs sont facilement contaminés par diverses substances, comment pouvons-nous bien les conserver pour pouvoir les manger en toute sécurité ?

1. Ne pas congeler

La congélation modifie la protéine, provoquant la solidification du jaune et pouvant éventuellement fissurer la coquille.

2. ne pas mélanger

Il y a de nombreuses bactéries pathogènes et de la saleté sur la coquille des œufs stockés. Ne les achetez pas et ne les mettez pas directement au réfrigérateur, ce qui provoquerait une contamination croisée avec d'autres aliments.

3. Don't put it sideways

Lors de la mise en place d'un œuf, faites attention à la grande extrémité, c'est-à-dire l'extrémité avec la chambre à air, ce qui peut prolonger le temps de stockage et empêcher le jaune d'œuf d'être jaune lorsqu'il est proche de la coquille.

Finally, it is important to note that eggs cannot be stored indefinitely. Generally speaking, eggs stored for 1 to 2 weeks are no problem to eat, and the longest should not exceed 1 month. Otherwise, not only will the nutrients be lost in large quantities, but they will also become "bad eggs".
