煮鸡蛋是一种常见的烹饪方法，但有时在将鸡蛋煮熟后，我们可能会注意到水变成了红色。这可能会引起我们的好奇心，想知道为什么会出现这种现象。实际上，这种现象是与鸡蛋内部的物质有关。

当鸡蛋煮沸时，内部的蛋白质会发生一系列化学反应。其中一个反应涉及到铁离子，这使得鸡蛋的水开始呈现红色。这种红色可能会让我们觉得不寻常，但实际上它并不会对食用安全造成任何威胁。

Boiling eggs is a common cooking method, but sometimes after boiling the eggs, we may notice that the water turns red. This may arouse our curiosity and make us wonder why this phenomenon occurs. In fact, this phenomenon is related to the substances inside the egg.

When eggs are boiled, the proteins inside undergo a series of chemical reactions. One of these reactions involves iron ions, which causes the water in the eggs to turn red. This red color may seem unusual, but it does not pose any threat to the safety of consumption.

尽管这种现象无害，但它的出现可能与鸡蛋的存放时间和质量有关。较旧的鸡蛋往往在煮沸过程中更容易出现水变红的情况。这可能与鸡蛋内部正在发生的氧化反应有关，即铁离子与其他物质相互作用而导致水颜色改变。

此外，水的酸碱性也可能对水的颜色产生影响。一些研究表明，较酸性的水更容易使鸡蛋煮后的水变红。这是因为酸性环境可以促使蛋白质和铁离子更容易发生反应。

英文翻译：

Although this phenomenon is harmless, its occurrence may be related to the storage time and quality of the eggs. Older eggs are often more likely to cause the water to turn red during boiling. This may be due to oxidation reactions occurring inside the eggs, where iron ions interact with other substances, causing a change in water color.

Furthermore, the acidity or alkalinity of the water may also affect its color. Some studies suggest that more acidic water is more likely to cause the water to turn red after boiling. This is because the acidic environment makes it easier for proteins and iron ions to react.

另一个可能的原因是鸡蛋内部本身的血丝。起初看到红色的时候，我们可能会误以为是血丝进入了水中，但实际上这只是蛋白质结构的一部分，被煮熟后使得水变红。这种血丝往往是鸡蛋的蛋黄和蛋白质之间的界面，通常并不对食用安全构成威胁。

总之，鸡蛋煮后水变红的现象是由于蛋白质内部发生的化学反应，其中涉及到铁离子。此外，鸡蛋的存放时间、质量以及水的酸碱性也可能对水的颜色产生影响。但无论出现什么颜色的水，只要确保鸡蛋煮熟了且没有异味，是可以安全食用的。

英文翻译：

Another possible reason is the presence of blood vessels inside the egg itself. When we first see the red color, we may mistakenly think that blood vessels have entered the water. However, it is actually just part of the protein structure that turns the water red after cooking. These blood vessels are often the interface between the egg yolk and the egg white, and they usually do not pose a threat to the safety of consumption.

In conclusion, the phenomenon of the water turning red after boiling eggs is due to chemical reactions that occur inside the proteins, involving iron ions. In addition, the storage time, quality of the eggs, and the acidity or alkalinity of the water may also affect its color. However, regardless of the color of the water, as long as the eggs are cooked thoroughly and there are no strange odors, they can be safely consumed.
