In this brief guide, we are going to answer the question “Is it safe to eat over-boiled eggs” with an in-depth analysis of is it safe to eat over-boiled eggs. Moreover, we will have a brief discussion about what causes a boiled egg yolk to have a green layer.
So if you are in search of an answer to Is it safe to eat over-boiled eggs then you need not worry as we are going to answer all your questions.
So without much ado, let’s dive in and figure out more about it
Is it safe to eat over-boiled eggs?
Yes, you can eat overcooked boiled eggs, even if they are significantly overcooked. If the egg was fresh when it was cooked, it should be fine to eat once you’ve finished cooking it, regardless of any green tint around the yolk.
Although you may have heard that eggs’ sulfur content makes them dangerous by releasing hydrogen sulfide, the amount of sulfur in eggs is safe for humans, even when they are overcooked.
Even if they release a small amount of gas into the egg, it will not affect you. Unless you have an egg allergy, boiled eggs should be perfectly safe to consume. Nobody has ever gotten sick from eating an overcooked boiled egg.
What causes a boiled egg yolk to have a green layer?
When you cut up a boiled egg, you might notice a green layer on the outside of the yolk. This layer of green is completely safe. It’s caused by iron and sulfur in the egg reacting with the surface of the yolk, and it won’t harm you.
Even if you haven’t overcooked the yolk, you may notice this ring around it from time to time. That’s usually a sign that the water you used to boil the egg contains a lot of iron.
It’s nothing to be concerned about, and it won’t harm you in any way. You can simply disregard it.
How to recognize an over-cooked egg
The proteins within an egg begin to unravel into longer structures as the temperature of boiling raises it above its normal cooking point. At a macro level, this manifests as a solidification of the egg whites and yolk.
However, if the egg is cooked for too long or at too high a temperature, the proteins’ molecular structure begins to break down and interact with the surrounding compounds, resulting in hydrogen sulfide. This manifests itself as a green or olive-colored film across the yolk’s surface.
Apart from the discoloration of the egg yolk’s surface, the egg whites will begin to turn brown as a result of a chemical reaction known to chefs as the Maillard reaction.
Aside from visual changes, another way to tell if the egg is overcooked is if the shell has started to crack, especially around the base. These cracks are fault lines in the calcium structure, through which gas escaping the egg squeezes as water evaporates from inside.
Unfortunately, overcooking a boiled egg alters the taste and texture of the egg, making it a less enjoyable meal.
At room temperature, how long do hard-boiled eggs last?
Because eggs are high in protein and have a porous shell that microbes can pass through, boiling them is an excellent way to kill any bacteria or fungi that may have made their way into their shell.
New colonies of fungi and bacteria will begin to take root once the eggs have been removed from the high temperatures of boiling water and allowed to cool on your countertop, especially if the egg has been overboiled and the shell has begun to crack.
Boiling eggs are only safe to eat for up to two hours if left on the counter with no other attempts at preservation, as any longer and microbial life forms will have produced harmful toxins in the egg.
This is especially true if the egg is heated before cooling to room temperature, as condensation of water will occur, speeding up the spoilage process by providing not only food but also water to the bacteria and fungi that opportunistically appear.
The egg will only be safe to eat for an hour or less in a room with a temperature above 90°F. “Make sure eggs are refrigerated within two hours of cooking and don’t leave refrigerated cooked eggs out at room temperature for more than two hours,” says the United States Department of Agriculture.
