Question about eggs?

Question

You know when you hard boil an egg for too long the yolk gets like green around it, why when you over cook a fried egg it doesn't get the same green on the yolk?

Answer 1

The green ring around the yolk is actually sulphur compounds in the yolk itself, which are trapped inside the egg. When the egg shell is broken, the sulphur can escape so there is no green tinge to the yolks.

Answer 2

Sometimes there is a greenish ring around hard-cooked egg yolks. It is the result of sulfur and iron compounds in the egg reacting at the surface of the yolk. It may occur when eggs are overcooked or when there is a high amount of iron in the cooking water. Although the color may be a bit unappealing, the eggs are still wholesome and nutritious and their flavor is unaffected. Greenish yolks can best be avoided by using the proper cooking time and temperature and by rapidly cooling the cooked eggs

Answer 3

is due to a chemical change, the formation of ferrous sulfide from iron in the yolks and sulfur in the whites, brought on by heat

and fried eggs and scrambled can turn green if cooked in an iron skillet, to stop this turn your heat down to a lower temperature.....and to prevent it in hard boiled eggs...cook for the recommended time...

Answer 4

the Green ring is sulfur trapped in the shell...fried eggs let the sulphur escape

Answer 5

One is cooked in water, one in oil.
