1. Avoid rinsing eggs with water when storing them. Some people think that the eggs they buy are too dirty, so they rinse them with water first and then store them. This is incorrect and will damage the nutritional value of eggs and even cause them to go bad. There is a layer of "white frost" on the outside of the egg shell, which seals the pores on the egg shell, which not only prevents bacteria from entering the egg, but also prevents the evaporation of water in the egg, keeping the egg liquid fresh and tender. After the eggs are rinsed with water, the "white frost" will fall off, bacteria will invade, and the water will evaporate, causing the eggs to deteriorate. Therefore, do not rinse eggs that need to be preserved. When preparing to use them, of course, you must clean the eggshells before cooking them.
2. Do not store fresh eggs in the refrigerator. Many people are accustomed to storing purchased eggs in the egg rack of the refrigerator, thinking that this can prevent the eggs from deteriorating. In fact, this can only be counterproductive. Putting fresh eggs on the refrigerator shelf is unhygienic and will damage the eggs and other foods in the refrigerator. This is because there are bacteria such as Bacillus subtilis, Pseudomonas aeruginosa, and Escherichia coli on egg shells. These bacteria can grow and reproduce at low temperatures, and the temperature in the refrigerator storage room is usually around 4°C, which cannot inhibit the growth and reproduction of microorganisms. This is not only unfavorable for the storage of eggs and may cause the eggs to spoil, but will also cause contamination to other foods in the refrigerator. The correct method is to put the fresh eggs into a dry and clean food bag, and then store them on the egg rack of the refrigerator, which is safer.
