How to test eggs in water if you think they’ve gone off

The water test is a great way to tell if your eggs have gone off.

Sometimes eggs can still be eaten if they’re passed the sell-by date written on their container.

Most store-bought eggs kept in the refrigerator remain fresh for weeks beyond the stamped date.

One trick is not to store your eggs inside the fridge door.

That’s because that part of the fridge is the warmest as it generates heat every time the door is opened, therefore, making them likely to rot quicker.

A bad egg can cause food poisoning.

Eggs, cracked into containers, can be stored in the fridge for two days and up to 12 months in the freezer.

If your egg floats to the top then it shouldn’t be eaten.

The science behind this egg test is based on the fact eggshells are very porous and semipermeable.

That means air can pass through the shell, which causes the egg to float.

Over time, are enters through the eggshell and as a result, its shelf life diminishes the more air enters the shell.

The more air that enters the shell, the more buoyant the egg becomes.

There are other fresh tests methods you can use, though none of them are as effective as the one outlined above.

You can hold an egg up to your ear and shake it.

If you hear liquid swishing around inside, it’s gone bad but if there’s no sound then it’s good to eat.

The sound you can hear usually points to an old egg yolk that has become watery.

Another method is the good old smell test, If it stinks then you can the egg away.

When cracked, eggs should have a neutral odour, not a strong smell such as sulphuric, gassy, or sour notes.

Cracking an egg on a flat surface is another way of determining its freshness.

Fresh eggs will have a bright yellow or orange yolk, where the egg white is slightly stiff and sits up around the yolk. The white of a not-so-fresh egg will be flatter and spread out.
