Simple-thinking eggs, but this habit of housewives makes the eggs full of bacteria

Many people have the habit of soaking fresh boiled eggs immediately in water for easy peeling. This action will cause the egg to cool very quickly, while the eggshell and the white part will shrink due to cold, creating a gap for easy peeling.

However, according to Associate Professor Dr. Nguyen Thi Lam, former Deputy Director of National Nutrition Institute, this approach is completely lack of science because water contains a large amount of bacteria. After the eggs are boiled, the eggs are no longer effective against bacteria.

If you want to make the egg easy to peel, the best way to do it is to boil the egg and put some salt in it. Edible salt has antiseptic effect, both makes the protein freeze, and also makes the shell of the eggshell shrink, forming a gap between the eggshell and the egg so it is easy to peel.

Another lack of scientific habits of housewives before putting eggs in the refrigerator often wipes or cleanses eggs clean. This is not true because there is a small covering on the eggshell, which causes the egg to be shiny and touched to feel smooth. It works to close the vents of chicken eggs, prevent dirt, bacteria in the outside environment from entering the egg and only allow oxygen to enter the egg.

If the eggshell is washed, the membrane will disappear, the airborne bacteria will enter the egg easily, causing the egg to fail. In addition, do not put eggs together with things with essential oils such as ginger, onion, chili . because the smell of these types will penetrate into the egg through the air vents in the eggshell, causing the eggs to be metamorphosed, if For long periods of time will cause the egg to become cancerous.

When choosing eggs in the market, want to preserve eggs for a long time, you should choose new eggs with outer shell with thin white, heavy and slightly rough chalk, which is a new egg, on the contrary, poor quality eggs.

In addition, the buyer can hold the egg and look through the light bulb or use a rolled up book or newspaper, scrambling eggs under sunlight. If you see that the air chamber of the egg is small, the yolk is not moving, complete, round and in the middle of the white, while the transparent white is red orange and light pink, it is fresh, new. If you are an old egg, when you leave it for a long time when you look at it, you will see that it is red with many veins, mobile lines and the space of the large gas chamber.

When shaking the egg gently in the ear, if the sound is heard, it is a poor egg, for a long time. Or if you shake and see that the egg is moving strongly, it is a broken egg and the egg is hatched.

In eggs, salted eggs are classified as the highest in calcium because during processing, the amount of calcium in eggshells dissolves into eggs.

Despite being nutritious, health experts also recommend not eating a lot of salted eggs because during processing, salted eggs use salt lime, oxidized lead to incubate eggs. In particular, the amount of lead if absorbed into the body exceeds the permitted level will cause headaches, insomnia, memory loss . In addition, it also adversely affects the absorption of calcium in the body.

If this lead content persists for a long time in the human body, it will cause calcium deficiency - the cause of osteoporosis.

In addition, people with hypertension, high blood fat, diabetes, overweight, and obesity should limit this dish because of high cholesterol in salted eggs. Moderate intake is 1-2 fruits / week.
