Just like overcooking can screw up a batch of scrambled eggs, aggressively boiling eggs will cause a green hard-boiled egg yolk. "When an egg is cooked for too long and/or at too high a. 521. First and foremost, it is imperative to mention that the greenish yolks of hard-boiled eggs are safe to eat.

We can thank a pigment found in plants called xanthophylls for the variance in yolk color. If you shop at an American supermarket. Turns out that egg yolk color is really just an indicator of the hen's diet! If they eat more yellow-orange carotenoids, or natural pigments, it affects and changes the yolk's color. In fact, while artificial color additives are not allowed to be added to chicken feed, naturally pigmented substances like marigold flowers are sometimes added. Here's a look at the chemistry behind why this happens. The green ring forms when you overheat the egg, causing hydrogen and sulfur in the egg white to react and form hydrogen sulfide gas. The hydrogen sulfide reacts with iron in the egg yolk to form a grayish-green compound (ferrous sulfide or iron sulfide) where the white and yolk meet. The science behind the green yolk phenomenon is pretty cool. The egg white contains sulfur compounds, and when exposed to high heat, these compounds can react with the iron present in the yolk. This reaction results in the formation of a compound known as ferrous sulfide, which is responsible for the green color..

Perhaps you've hard-cooked an egg only to discover a green ring around the yolk when you crack it open.

Pale yellow vs. bright yellow egg yolks. The colour of an egg yolk is primarily determined by the types of pigments the hen consumes in her diet. Eggs that come from hens that are fed a predominantly wheat-based diet tend to have a more pale yolk. Diets rich in carotenoids will have a deeper colour in the yolk. The grey-green discoloration of the egg yolk in hard-boiled eggs is caused by overcooking. The heat makes the iron in the egg yolks react with the sulfur in the egg whites. The resulting dark ferrous sulfide looks green on top of the yellow egg yolk. To avoid the green tinge, it's key to prevent the iron in the yolk from being released.
Should you eat a hardboiled egg with a greenish yolk?
Step 3: Cook the Green Eggs. Spray the fry pan with cooking spray and heat it over medium low until warm. If your heat is too high, the eggs will not cook uniformly. Once the pan is hot, pour one of the whites into the pan. Pour one yolk out of the bowl onto a spoon and gently slide it onto the center of the whites in the pan. Now iron sulfide is formed, which already appears greenish in nature. The typical green-gray border around the yolk is formed because only the surface of the yolk is in contact with the egg white.
