Why do hard boiled eggs smell?

When it comes to healthy food choices, many experts and nutritionists promote the consumption of eggs to provide the body with good protein. To make eggs even more healthy, nutritionists often prefer to have them hard boiled rather than scrambled of fried. The only concern with hard boiled eggs is that they often smell bad. Some people simply dismiss the smell as something natural for eggs while others can’t stand the smell and they’d rather cook the eggs in a different way. The bad smell that often comes after boiling the eggs is usually a result of overcooking. When the eggs are left on the boiling water for too long, the protein content in eggs will literally emit a foul smell. This smell stems from the hydrogen sulfide content in the egg whites that reacts with the iron content of the yolks. With this chemical reaction, the hard boiled eggs will then emit a foul smell. This foul smell is similar to the scent of sulfur with some people even referring it to fart-like.

In order to prevent the smell of hard boiled eggs, people just need to cook their eggs properly. It takes about 10-12 minutes to properly cook medium sized eggs. Once done, it also helps to have the eggs removed from the boiling water immediately to stop the cooking process. Some people even recommend placing the newly cooked eggs in cold water to literally stop them from cooking further. With this technique, there is a greater chance that the hard boiled eggs will not smell foul or bad. Aside from the foul smell, a pretty good indicator that the eggs are overcooked is the color of the egg yolks. Properly cooked eggs still have yellow egg yolks and when they become too gray on the outside, it simply means that the eggs spent too much time in boiling water. If this is always the case, people just need to lessen the time of cooking to ensure that eggs won’t be overcooked and won’t smell bad.
