When you boil eggs, hydrogen sulphide - a toxic gas is released in the whites of the egg. This happens especially when you overboil the eggs. If you have noticed, overcooked eggs have a green coating on their yolk, which is a signal that you should not eat them.
Shelly McKee, a food scientist at Deb-El Foods and an expert on egg chemistry, said that boiling an egg for a long time would cause it to expel moisture. As the proteins in the egg white clump together ever more tightly, they would squeeze out the water contained within the egg.
For one to four eggs, bring the water to a rolling boil, cover the pot, and turn the heat down to its lowest setting for 12-14 minutes. For five to eight eggs, cook for 15 to 18 minutes. For nine to one dozen eggs, cook for 20 minutes.
Overcooked hard-boiled eggs are safe to eat (in moderation) as they release a minimal amount of iron sulfide, which would be dangerous if consumed in excess. If an egg is overcooked, it'll develop a bluish-green tint around the yolk, but as long as it is fresh, it can be eaten safely.
As soon as the water begins to boil, turn off the heat and cover the pot. Leave the eggs in the hot water for anywhere from 10-12 minutes, depending on how you like your eggs. The 10-minute eggs will have vibrant, creamy yolks, while the 12-minute yolks will be paler and opaque, with a chalkier texture.
Bring the water to a boil, gently stirring the eggs several times. As soon as the water boils, remove the pot from the heat, cover, and let the eggs sit for 15 minutes (13 minutes for small eggs or 17 minutes extra large eggs).

For a less runny but semi solid egg yolk with a slightly firmer white, boil the egg for eight minutes. For a soft yolk and firm albumin, boiling the egg for ten minutes should do the trick. For a fully hard-boiled egg with a firm yolk and firm albumin, boil the egg for twelve minutes.
According to The Kitchn, the first sign that your boiled eggs were left on the stove too long is if their yolks are a strange gray or white color, or seem to be falling apart. The other indicator that your eggs were over-boiled is if they smell like sulfur after you freshly peeled them.
Chickens and other live poultry can carry Salmonella bacteria. These germs can spread from the birds to their eggs. If you eat raw or undercooked eggs, you can get sick. Always handle and cook eggs properly to prevent illness.
No. It is not advisable. Application of heat 30 minutes boiling to the egg, The egg white will harden because of the protein coagulation and will not get digested by our body. What can I eat with boiled eggs?
Boil for 6 – 7 minutes over medium-high heat for perfect hard-boiled eggs. Using a slotted spoon, transfer them to a large bowl of ice water and let them cool for a few minutes. Or you can place them under cool running water to stop the cooking. Peel and serve the eggs immediately.
To avoid getting a green yolk, cook your eggs just long enough to reach the desired doneness—no more. And quickly plunge the cooked eggs into cold water to stop the cooking process and minimize the iron-sulfur reaction. Some people also say that the cold-water plunge makes eggs easier to peel.
Place eggs in saucepan. Fill pan with cold water until eggs are covered by one inch. Heat water over medium heat until it is at a full rolling boil. Let eggs cook for 15 seconds, then remove pan from heat, cover with lid, and leave for 20 minutes.
The first problem is a matter of stomach volume. Fifty boiled eggs occupy about three litres. The average empty stomach volume is ca 1-1.5 litres, so it is unlikely that Luke's stomach could hold 50 eggs. However some large people may have larger than average stomachs so this might not be a problem.
Bring 3 quarts (2.8L) water to a boil in a large pot. Carefully lower eggs into pot and continue to boil for 30 seconds. Cover tightly, reduce heat to low (water should maintain a bare simmer), and continue cooking for 11 minutes. Serve immediately if serving hot.
Set 12 eggs or as many as you desire (in a single layer) into a large saucepan. Fill pot with water to completely cover the eggs at least 1 inch above eggs and turn heat to high. Bring water to a boil, takes approximately 15 minutes. As soon as eggs start to boil, let boil for 10-12 minutes (I do 11 minutes).
A nine minute cook time is best for large eggs. To avoid overcooking make sure that your water never passes the 180-degree mark and be sure to use a timer. After your timer goes off, give your eggs a cool bath under cool water for a few minutes.
Most healthy people can eat up to seven eggs a week without affecting their heart health. Some choose to eat only the egg white and not the yolk, which provides some protein without the cholesterol.
Denaturation is what happens when heat is applied to the eggs. Chemically, this is the process by which the chains of amino acids are changed from their original (or native) state. The heat coming from your stove denatures the protein by disrupting some of its bonds that held the molecule into shape.
Our answer. The dark ring that forms around the yolk of a hard boiled egg is called a sulphur (sulfur) ring. When the egg is boiled the sulphur and hydrogen in the egg white combine to make sulphur dioxide gas, and this gas reacts with the iron in the yolk to form a dark ring.
The best way to salvage an under-boiled egg is to get it back into hot water. You can either reboil them directly on the stove, or put them in a bowl that can handle boiling water and pour hot water over the eggs. Note: Do not cook boiled or partially boiled eggs in the microwave; this will cause them to explode.
