Can 100 ℃ boiling water cook eggs

100 ℃ boiling water can cook eggs, but the specific degree of ripeness depends on the soaking time. Egg whites begin to solidify at 60 ℃, while egg yolks denature at around 70 ℃. Continuous high temperatures can achieve a fully cooked effect. The main components of eggs are protein and water, and high temperatures can damage the protein structure and cause it to solidify. Put raw eggs into boiling water at 100 ℃, and the outer layer of protein will quickly solidify to form a protective layer, gradually transferring heat to the yolk. Short term soaking may result in soft boiled eggs, with solidified protein and semi liquid yolk; Continuous heating for 5-8 minutes can completely solidify the egg yolk. The difference in boiling point in different altitude areas will affect the actual effect, and the heating time needs to be extended in high-altitude areas.

In special circumstances, if refrigerated eggs are directly poured into boiling water, the eggshells may rupture due to excessive temperature differences. It is recommended to let it warm up at room temperature and simmer over low heat, or turn off the heat and cover it with a lid after the water boils, and let it simmer until fully cooked. Shell eggs have slow heat transfer when heated. If you want to achieve rapid maturation, you can break up the egg mixture and pour it into boiling water to make egg yolks. Eggs may be contaminated with Salmonella, so it is important to ensure that the center temperature reaches 70 ℃ or above for effective sterilization. Eggs are a good source of high-quality protein and lecithin, and it is recommended to pair them with whole grains and vegetables to balance nutrition. People with weak digestive function should choose fully cooked eggs, and fitness enthusiasts can consume soft boiled eggs appropriately to retain more vitamins. Avoid using metal utensils to store cooked eggs for a long time during cooking to prevent the reaction of iron sulfide from affecting the color. Overnight soft boiled eggs should be refrigerated and thoroughly heated before consumption. Elderly and children are recommended to consume fully cooked eggs cooked on the same day.
