Fresh-keeping skills of eggs

1, refrigerator preservation

Before putting it in the refrigerator, we need to know that putting eggs in the refrigerator is not a simple matter. Because there are many pores on the surface of eggs, bacteria can easily get in, and many eggs are unclean. So before we put the eggs in the refrigerator, we should first clean the surface of the eggs, dry them with a wet cloth, and don't rinse them with water. Water can easily get into eggs.

2. Big head up

It is said that there seems to be an air bag or something in the egg. If you lift the big head, it will just hold against the airbag. On the one hand, eggs are not easy to go bad, on the other hand, the nutrition of eggs is not easy to lose. So, whether in the refrigerator or at room temperature, remember to put the eggs up.

3. Don't put it with greasy food.

Spicy cooking essences such as garlic and ginger have a strong taste, which can easily penetrate into the egg through the capillaries of the egg. After the odor, the taste of the egg is gone. Not only garlic and ginger, but also many foods with strong flavor should not be put with eggs. So this also confirms the importance of preserving eggs in an independent space in the previous step.
