What is the difference between eating raw eggs and eating hard boiled eggs?

Don't eat eggs raw, there will inevitably be harmful bacteria in the process of egg fertilization, and the egg white is not cooked is not conducive to human absorption, what to eat raw eggs ==!

Raw eggs can be eaten, but there are a lot of bacteria, so it is not recommended! It's easy to get sick, so it's better to eat hard-boiled eggs.

The nutrients are basically the same.

The nutritional value of cooked is higher and safer, and cooked people generally use steaming, boiling, and frying methods to cook, among which the method of steaming can retain the nutritional value of eggs to the greatest extent.

I have taken a food safety training course before, saying that although the nutritional value of raw eggs is better than that of cooked eggs, raw eggs will carry some harmful bacteria, and eating raw will accumulate these bad bacteria, it is recommended to eat after cooking, and the best effect of cooking is that the center of the egg yolk is just coagulated. It takes about 13 minutes to boil eggs in cold water and 8 minutes to boil water.

Raw eggs are unhygienic and not easily digested and absorbed. Eggs are often contaminated with Salmonella and parasite eggs and are susceptible to disease if left untreated. In addition, egg whites also contain a substance that is harmful to the human body, called antitrypsin, when the human body ingests raw eggs, antitrypsin enters the digestive tract, interferes with the hydrolysis of protein by trypsin, and affects the digestion and absorption of protein.

Raw egg whites also contain avidin, which is a harmful substance. If you eat a large number of raw eggs for a long time, the avidin in the raw egg white is combined with biotin in the body to form a stable compound, so that biotin can not be absorbed by the intestinal wall, which can lead to biotin deficiency disease, resulting in a series of symptoms, such as mental fatigue, muscle aches, hair loss, inflammation, loss of appetite, weight loss, etc. Recently, it has been reported that raw eggs are prone to fermentation and spoilage as they pass through the intestines, and sometimes nitroso compounds may be produced.

This compound has a carcinogenic effect. After the egg is boiled or cooked by other methods, the salmonella and parasite eggs in it are killed, the antitrypsin and avidin are also destroyed, and the other nutrients are intact, and the protein becomes loose and easy to be digested and absorbed, which can achieve the purpose of making full use of various nutrients in the egg. Therefore, instead of eating raw eggs, you should eat cooked eggs.

What is the difference between raw and cooked eggs? In daily life, many people may confuse raw eggs with cooked eggs, so what can be the difference?

1. Rotation method. Place the egg on a table that is smooth horizontally, do not be smooth horizontally, then put the egg on the table, rotate the egg on the table, and then use one finger to suddenly fix the egg for a second or two and then let go, to see if the egg continues to rotate, if it continues, it is raw, otherwise it is cooked.

2. Look at the appearance. The appearance of raw eggs is relatively rough, and you can see small protrusions one by one, and the appearance of cooked eggs is relatively smooth, and the feel is smoother than that of raw eggs. If you are interested, you can compare the hard-boiled eggs, and the comparison will have an effect.

3. Smell the smell. If it is a freshly boiled egg, it can smell a relatively strong aroma of hard-boiled eggs. Raw eggs, on the other hand, have a slight lime taste.

4. Shaking method. Hold the egg between two fingers and gently shake it in your ear, you can feel the liquid inside the egg shaking when you are raw, and the feeling of being heavy in a cooked egg.

5. Light irradiation method. Put the eggs under the light and see that the inside of the eggs is clear and transparent, which is a raw egg, otherwise it is a cooked egg. This method is less reliable.
