The “dirty” egg has a natural barrier. In fact, the surface of the egg is naturally covered with a layer of antibacterial material, which makes it difficult for outside microorganisms to invade and therefore does not deteriorate easily. Although many people think that eggs have a dirty shell and may be covered in feces, weeds and dirt, these are the natural barriers of eggs. Natural! Screen! The barrier! So, there is no need to refrigerate the “dirty” eggs you buy in the market. Just keep them in a dry, ventilated, cool and light-free place. However, the boxes of eggs bought in supermarkets have been washed and disinfected manually, and although the dirt has been washed off, the outer layer of the “protective film” has also been removed. Therefore, such eggs must be refrigerated. Diligent friends will be placed one by one into the grid of eggs, some people are too lazy or can not be placed, the whole bag to the refrigerator a put …… but you know what, eggs in the refrigerator “posture” is also a matter of concern, put the wrong can not be good! The correct way to put eggs large head up, small head down, and not! not! horizontal! put! Experts say that the gas chamber of the egg is at the big end, so if the big head is put down, the gas chamber will be compressed by the egg liquid, resulting in poor shell respiration and affecting the freshness of the egg. So the small head of the egg is placed downward, which can extend the freshness of the egg. In addition, we should note that ginger, garlic, onions, onions and seafood should not be put together with eggs because there are many small pores in the eggshell, and the strong smell of these foods will burrow into the pores and accelerate the deterioration of fresh eggs, and the eggs will stink after a little time.

Myths about eggs 1, boiled eggs cooled and then peeled We will wait until the eggs naturally cooled and then peeled (for the simple reason that immediately peeled will be hot), but this is not only very difficult to peel and the egg white will remain on the shell, in fact, the boiled eggs into cold water, it will not appear this phenomenon. Teach you a shell boiled eggs tips: take a paper towel to wrap the boiled eggs, and then roll the eggs on the table, and then peel the shell is super good peel! 2, the longer the eggs are cooked the better In fact, the longer the eggs are cooked, the more difficult it will be to absorb the protein in the yolk, the same way when frying eggs oh.
