Adding this ingredient to the water while boiling eggs makes peeling them easier

It Increases the pH of the Water: When baking soda, or sodium bicarbonate, is added to water, it helps to make the environment more alkaline. This change in the boiling water can create slight differences in the structure of the egg white. It is stated that a more alkaline environment can help the egg white to form less tightly bound to the membranes on the inner surface of the shell. Thus, separation between the shell and the egg white can occur more easily after the egg cools. This effect is particularly noticeable in fresh eggs during peeling. However, moderation is necessary as using too much baking soda can negatively affect the taste or texture of the egg.

It Can Reduce Egg White Sticking to the Shell: Two thin membranes are located just beneath the eggshell, and the egg white comes into contact with these structures. When the egg is fresh, the bond between the egg white and these membranes can be stronger. Therefore, peeling very fresh eggs after boiling can sometimes be quite difficult. Adding baking soda to the water can help loosen this bond by creating a more alkaline environment. As a result, it can become easier to separate the egg white from the shell when removing it. However, the effect of baking soda may vary depending on factors such as the age of the egg and the cooking conditions.

Making Peeling More Practical: Breaking the shell into small pieces when peeling a hard-boiled egg can prolong the process. Furthermore, the egg white breaking along with the shell prevents the egg from looking neat. Using baking soda in the boiling water can make it easier to separate the shell from the egg, helping to remove larger pieces. This allows you to peel the egg in larger pieces instead of removing small pieces one by one with your fingers. However, it's important to know that this doesn't guarantee a perfect result and may not have the same effect on every egg. Putting the egg in cold water after boiling is also an important practice that helps the shell separate more easily.
