Just boiled eggs can be rinsed with cold water 4 major disadvantages of rinsing eggs with cold water

Many people take cool water to rinse the eggs after boiling them, or soak them in cool water for a while to cool them down so they can be peeled. So can you rinse freshly boiled eggs in cool water?

Can you rinse freshly cooked eggs in cold water?

It is best not to rinse freshly cooked eggs in cold water. It is true that boiled eggs can be easily peeled with cold water, but it is likely that the shell of the boiled egg will be broken, and cold water contains certain bacteria that can easily invade the egg, resulting in a shorter storage time and easy deterioration of the egg.

The disadvantages of rinsing eggs with cold water

1. Re-contamination of eggs

Because the surface of clean eggs originally had a gelatinous film on the shell, but after boiling at high temperatures, this film has been completely destroyed. Without the protection of the film on the shell, bacteria can invade the egg through the small pores that are distributed throughout the shell.

2. Affects the quality of eggs

The large side of the egg head originally had a relatively large space for the air chamber, and when the egg is boiled, the air pressure inside the chamber rises as the temperature around the egg rises, and the air inside the chamber is squeezed out. If the cooked egg is immersed in cold water, the air pressure in the chamber will be negative and the cold water will easily enter the egg through the air holes in the shell, while the bacteria brought in by the cold water will easily grow and multiply inside, seriously affecting the quality of the egg.

3、Babies are prone to diarrhea after eating

Since cooked eggs are susceptible to secondary contamination by bacteria in cold water after being excited by cold water, such eggs for babies are equivalent to indirectly feeding raw water to babies, which can easily lead to diarrhea.

4, easy to spoil and not easy to save

If the cold water washed eggs at once did not eat, the cold water invasion of eggs, but also bacteria will be brought into the egg, so that direct contact with the protein, and nutrient-rich protein just for the growth and reproduction of bacteria to provide high-quality nutrients. At the right temperature, the bacteria will quickly break down the egg white, causing the egg to spoil.

Easy to peel eggs with cool water but not good

When you put a cooked egg into cool water, the temperature drops suddenly and the negative pressure (less than the external pressure) is formed in the hollow of the egg. The cool water will enter the egg through the shell hole due to the negative pressure and penetrate between the inner shell membrane and the egg white, making it easy to separate the inner shell membrane from the egg white, but the rinsed egg will have the above-mentioned bad effects.

How to peel hard-boiled eggs without using cold water

Boil eggs with a little salt beforehand. To avoid the bad effects of soaking eggs in raw cold water, boiled eggs can be placed in cool boiling water that has been boiled with salt beforehand. Eggs soaked in this cool water are easy to peel and less likely to break. If you are afraid of trouble, you can also not use cold water, although it is difficult to peel the skin, but resistant to preservation, not easy to break.

Nutritional content and effects of boiled eggs

Boiled eggs are rich in nutrients, including protein, cholesterol, unsaturated fatty acids and a variety of minerals such as calcium, iron and phosphorus, among which protein is the highest, cholesterol is the second highest, and unsaturated fatty acid content is low.

1、Strengthen and strengthen the body

Boiled eggs have the highest protein absorption rate of all the ways to eat eggs, and are currently the best way to supplement protein in food, which can play a role in strengthening the body.

2, education and brain

Eggs contain a lot of lecithin, which is an important substance for human brain development, and the lecithin in boiled eggs is less damaged and highly absorbed, especially for children and the elderly, to educate and strengthen the brain.

3, blood tonic effect

The content of iron in boiled eggs is not low, and is also very well absorbed. Iron is the main synthetic raw material for human hemoglobin, and eating a boiled egg every day can slightly improve the symptoms of iron deficiency anemia.

4、Lower cholesterol

Eggs contain a certain amount of cholesterol, it is not advisable to eat more, but if you eat one, the intake of cholesterol is not very high, and eggs also contain lecithin, which has a strong cholesterol-reducing effect on the protection of the liver is very effective.

Precautions for boiled eggs

1. Eggs should not be boiled for too long

Cooked at high temperature for too long, it is easy to damage the nutritional value of eggs, reducing the nutritional value of eggs, and boiled for too long eggs are not easy to digest, generally 5-8 minutes is appropriate, and the best cold water into the pot Oh!

2. Clean the eggs before boiling them

Eggs may carry salmonella in their shells, and in the process of boiling eggs, eggs may be accidentally broken, making them susceptible to bacterial contamination and causing discomfort after consumption.
