![]() ![]() ![]() Fortunately for all you egg lovers out there, the volume of hydrogen sulfide released from an overcooked egg is so minuscule that it doesn’t pose a threat to anyone in the vicinity. You might have guessed by now that the characteristic “rotten egg” smell is actually hydrogen sulfide gas. Overcooked eggs usually have a green ring around the perimeter of the egg yolk. According to Foodies Family, boiling eggs makes the egg whites and yolks solidify, and also gets rid of bacteria such as. Boil your eggs for about 9-12 minutes to cook them properly. Overcooking Eggs Turns The Yolk Green And Forms The Poisonous Iron Sulfide. While there are no immediate effects, it could lead to food poisoning. Apart from being horribly stinky, it’s also quite poisonous and highly flammable – to the point of being violently explosive. Overcooked eggs contain ferrous sulfide, which is toxic. Since it’s heavier than both nitrogen and oxygen – the two primary gases found in our atmosphere – hydrogen sulfide is found in low wells, caves and mines. Now, one thing that you should know about hydrogen sulfide is that it stinks! Big time!Īsk anyone with a degree in chemistry about the first thing that comes to their mind when you say ‘hydrogen sulfide’, and in all likelihood, their initial response will include the mention of its unbelievably foul smell. Ovalbumin, the major component of egg white which consists of 54 of the egg white start to set at 80☌/180☏. This dilemma can be corrected by boiling the eggs at the sub-boiling point of water. During denaturation (i.e., when you boil the egg), the sulfur in the proteins of the egg white combines with hydrogen to form hydrogen sulfide. However, some argue that eating overcooked hardboiled eggs can be dangerous to the body and should not be eaten. Unfortunately, many of these eggs are overcooked, taste rubbery and have an unsightly greenish layer at where the egg white and yolk meet. Those proteins, in turn, contain a small amount of sulfur. The best results I got when cooking large eggs was when I set the temperature to 390☏ (200☌) for 10 minutes (hard-boiled) and 390☏ (200☌) for six-and-a-half minutes (soft-boiled). That’s why an egg becomes hard when boiled, hence the name ‘hard-boiled’ egg.Īlso Read: What Happens When An Egg Is Boiled?Īs mentioned earlier, egg whites contain proteins. The longer you continue to heat the egg, the closer the proteins get to one another and coagulate, forming additional bonds within their clusters. Such a change in the original (or native) structure of proteins (or nucleic acids) in the presence of heat (or other external agents, such as a strong acid or base, or an organic solvent, like chloroform or alcohol) is called the denaturation of proteins. When the egg is raw, these proteins are all tangled up with each other, but when the egg is boiled, i.e., when heat is applied to the egg, these proteins unfold and form new bonds among themselves. ![]() The proteins found in egg whites are actually long molecules, composed of chains of amino acids that are linked together. Is overcooked eggs poisonous Overcooked eggs contain ferrous sulfide, which is toxic. The white of an egg is 12% protein, while the yolk is composed of 16% protein. Proteins are one of the primary components of an egg. ![]()
