What does a bad egg look like when it is cooked

As a high-protein food, the nutrients in eggs are more easily absorbed by the human body and can provide the body with necessary nutrients, so it is a very nutritious food. However, due to the protection of the eggshell, we cannot see the state of the internal substances of the egg, so it is difficult to judge whether the egg is good or bad. However, if we accidentally eat spoiled eggs, it will have a very bad effect on our body, so it is particularly necessary to understand the state of eggs after they have spoiled.

If the yolk is dark red after cooking, it is a bad egg.

1. Eggs, also known as chicken eggs and chicken eggs, are eggs laid by hens. They have a hard shell on the outside and an air chamber, egg white and yolk inside.

2. Eggs can be divided into three main parts: eggshell, egg white and egg yolk. Eggs contain a large amount of vitamins and minerals and proteins with high biological value. They are one of the foods commonly consumed by humans.

3. Boiled eggs are one of the most common ways to eat eggs. It is mainly made by putting the eggs into water and cooking them. ,

4. If the eggs are boiled in the right way, the nutrient absorption rate of the boiled eggs can reach 100%, making it a popular choice for breakfast or nutritious meals.

5. Although boiled eggs are rich in nutrients, eating too many eggs can cause indigestion. Therefore, it is not advisable to eat too many boiled eggs. Generally, it is advisable to eat no more than one boiled egg a day to avoid endangering your health.

6. If eggs are boiled in boiling water for more than 10 minutes, a series of chemical changes will occur inside the eggs. The protein structure will become tighter and less likely to come into contact with the protein-digesting enzymes in the gastric juice, making them more difficult to digest.

7. The protein in eggs contains a lot of methionine. After being heated for a long time, it will decompose into sulfide, which reacts with the iron in the egg yolk to form iron sulfide that is not easily absorbed by the human body, resulting in a lot of nutritional loss.

8. Undercooked eggs are more harmful. Raw eggs are not only contaminated with Salmonella, but also contain two harmful substances: anti-enzyme protein and anti-biotin protein.

9. The former will affect the digestion and absorption of protein, and the latter can combine with biotin in food, leading to biotin deficiency in the human body and causing symptoms such as mental fatigue and muscle soreness.

10. The above two substances will be destroyed once the eggs are cooked.
