How long do cooked eggs last?
Eggs must be refrigerated within 1-2 hours of cooking or boiling. Refrigerated cooked eggs will only last 3-4 days in the fridge. After this time, the eggs become unsafe for consumption and must be thrown even If they appear alright. Store in an airtight container. Let the cooked eggs come to room temperature before storing them.
At what temperature should eggs be cooked?
An egg cracked or intact, should be cooked to an enteral safe temperature to ensure that the harmful pathogenic bacteria have been destroyed. Follow the guidelines given below, provided by the FDA, to cook your eggs safely in order to avoid a food-borne illness.
|Omelets, frittatas, and hard-boiled eggs||Cook to an internal safe temperature of 144°F–158°FOr 62-70°C|
|Egg white omelet||Cook to an internal safe temperature of 144°F–149°F or 62-65°C|
|Scrambled, over-hard, fried, and poached egg||Cook to an internal safe temperature of 144°F–158°F or 62-70°C|
The shelf-life of eggs
Fresh eggs will preserve their freshness for 4-5 weeks in the refrigerator and If you want to keep them longer, you can boil them. Boiled eggs will retain their quality for almost 1 week in the refrigerator and less than 2 hours in the pantry.
The shelf-life of raw egg yolk and raw egg white is less than 2 hours in the pantry and 2-4 days at the refrigeration temperatures.
Why do eggs go bad?
Eggs go bad due to bacteria or fungal invasion. The most infamous bacteria that spoils eggs is Salmonella. Refrigeration prevents the growth of bacteria. It is recommended to heat food to an internal temperature of 71 degrees celsius to kill salmonella and avoid food poisoning.
How to check If the eggs are fresh or not?
In order to distinguish a fresh and old egg, two very famous methods are as follows.
This is the simplest way to identify fresh eggs. For this test, carefully place an egg in a bowl filled with water. If the egg jumps to the surface and starts to float, it is old. If the egg settles down at the bottom, it is fresh.
The science behind it is after an egg is laid, its temperature drops during which an air cell forms inside of it at the larger end. This space grows larger due to constant evaporation. Therefore an older egg with a larger air pocket floats over water.
Egg candling is performed using a candling lamp to check the stage of chick development inside a fertilized egg. It can also be used to check the freshness of an egg.
A bright light source is used to see through an egg from its broader side. If it looks empty or you feel the egg contents movings inside because of larger air space, the egg is old.
How to store eggs safely?
- Keep eggs in a cool dark place in the pantry.
- Always refrigerate washed eggs.
- Keep track of the expiration dates.
Can eggs be frozen?
Freezing eggs is not recommended. Freezing temperatures considerably damage the quality of an egg such as:
- If an egg is frozen intact, the egg and yolk will start to take up more space when they freeze, consequently, breaking the eggshell.
- In addition to this, the yolk inside it will stiffen and look as if it has been boiled.
The egg white will not be able to serve the purpose of aeration in your baked goods because of textural loss as a result of protein denaturation. So If you do not want to waste your money by freezing eggs then whisk it properly, put the mixture in a freezer bag, and store it for up to 4 months.
If you wish to store your raw egg white and yolk separately, you can save their quality by whisking your egg white or yolk with sugar, salt, or corn syrup depending on their end-use.
How to identify rotten eggs?
- Rotten eggs give off a foul smell.
- If the eggshell appears sticky and dusty, discard your egg because it indicates bacterial and fungal contamination respectively.
- If there are cracks on the eggshell, the chances of bacterial contamination are high. It is better to toss it in the bin.
