¿Cómo saber si tus huevos son frescos?
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.
Regulaciones locales para los huevos
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.
¿Cómo probar si un huevo es fresco?
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 cámara de aire de un huevo recién puesto no mide más de 3 mm. Si la cámara de aire de tu huevo es significativamente más grande que esto, la frescura será menor. Por supuesto, una temperatura y humedad de almacenamiento inadecuadas acelerarán la pérdida de peso de los huevos.
¿Cómo almacenar correctamente los huevos?
Los huevos se contaminan fácilmente con varias sustancias, ¿cómo podemos conservarlos correctamente para poder comerlos con seguridad?
1. No congelar
La congelación cambia la proteína, haciendo que la yema se endurezca y posiblemente agriete la cáscara.
2. no mezclar
Hay muchas bacterias patógenas y suciedad en la cáscara de los huevos almacenados. No los compre y póngalos directamente en el refrigerador, ya que esto provocará contaminación cruzada con otros alimentos.
3. Don't put it sideways
Al colocar un huevo, preste atención al extremo grande, es decir, el extremo con la cámara de aire, lo que puede prolongar el tiempo de almacenamiento y evitar que la yema se vuelva amarilla cuando está cerca de la cáscara.
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".
