Knowledge about eggs: how to store?

The big head of the egg is up, only for 10 days

Big head of egg

According to Li Wendong, a national senior Chinese cookery chef, since the proportion of egg yolk is smaller than that of protein, the head of the egg is selected to face upwards, and the head is faced down and stored upright. Even if the protein is thinned, yellowing and skinning will not occur quickly. This will not only prevent microorganisms from invading the egg yolk, but also help ensure the quality of the eggs.

2. Note isolation

Fresh eggs are alive, and they need to breathe through the pores on the shells, so they have the ability to absorb odors. If mixed with garlic, leeks and other foods with bad odor during storage, then the eggs will have odor, affecting the effect of eating.

3 do not seal storage

Wang Nan, senior food inspector of the country, believes that some people think that the eggs are dirty and seal them in a plastic box. This is not correct. Because the eggs need to be "breathed" during storage, the moisture will evaporate outwards, and will be stored in a plastic box. The inside of the box will be airtight and the environment inside will be wet. This will cause the protective film outside the shell to dissolve and lose its protective effect, accelerating the deterioration of the eggs. .

4. Do not wash before storage

Eggs cannot be washed with water. The protective film outside the eggshell is water-soluble, and washing will destroy the protective film. You can buy clean eggs at ordinary times, or buy ordinary eggs in the freezer to store them separately to avoid cross-contamination.

5. Summer daily temperature preservation for about 10 days

Public dietitian Li Shipeng said in his microblogging that eggs can be preserved for 40 days at a temperature of 2 to 5°C, about 15 days in winter, and preserved for about 10 days at room temperature in summer. Eggs exceed the shelf life, freshness and nutrient content are affected. Remind everyone: Do not buy too much eggs at a time, eat enough for a week.
