Is it good to
keep eggs in
How much can they withstand refrigerated? What
to do with those who are cracked in the
package? How do you know that are still
fresh? Here you have the product key so
important in our diet.
When we purchase in the supermarket eggs are
in a section without refreshment. In normal
shelves are stacked and then, once home, go
straight to the fridge. Why have so internalized
this habit? Is it better to keep cold than at room
temperature? Do they lose properties days as
the days go? Here we give the keys to this key
product in the best diet.
There is a reason that would explain why in
supermarkets are stacked eggs at room
temperature. "When you go from cold to hot, it
is normal for water to condense on the surface,
like a yogurt or fruit. In the egg is very
dangerous because it has a porous and allow
any external contamination, when they are wet,
pass into the egg a lot easyer, "says Maria del
Mar Fernandez , director of the Institute for
the Study of the Egg . " The reason that eggs
not chilled at the point of sale is to avoid
the temperature difference from cold to
hot "he says.
"Subjecting the egg to various temperature
changes deteriorate its quality"
"As is normally sold in the two days after laying,
it is normal that in four days it arrives home,
and those days at room temperature is not a
problem if you after that keep them in the
fridge. Yeah that would be a problem
subjected to various temperature
changes , ending the final quality deteriorating
egg, "says Maria del Mar.
But why diminishes the freshness of an
egg? "has to do with losing water inside, and is
greater when we have higher temperatures
outside and when the humidity is very low." In
Spain, therefore, the egg lose freshness
very quickly if not stored in the
fridge . Regarding a recent study published in
the UK who threw the conclusion that it is
indifferent to keep them in the fridge or not ,
this agricultural engineer answers us that "it is a
mistake because on the labeling should put
it is advisable to keep eggs
refrigerated for losing less water and
freshness, so as to endure better quality. "
With the passage of time, the egg is losing
properties , but especially as it reduces the
amount of water present in it. To lose air and
enter the consistency of the white is lower, and
the yolk, in turn, flattens. In this sense, "does
not affect the nutritional properties, but the
quality of the egg is not the same and has the
same qualities to the kitchen," notes Maria del
Successfully saved in the fridge, this product
can endure even beyond the recommended
28 days after laying. This period would be to
its "Best before" constantly confused with the
expiration date. A mistake, because from the
Egg Institute, report that " can be consumed
after the date of the package if the crack it is
found to have good color and good smell, but it
is advisable to use for cooking and not for crude
preparations (like mayonnaise or merengue) '.
"You have to wash the egg at the time
before eating and not to save»
Thus we continued concern, how do you
know if an egg still fresh? Maria del Mar
told us that "the yolk should be high and we
must distinguish two zones in the clear, one
thicker and a more liquid. We can also see the
shape of the bubble rounder end of the egg,
called "air chamber".
The smaller, fresher the egg, if it goes bigger, is
a symptom that is older. " The air chamber is
the official measure of freshness of this
product. Hence the custom of laying eggs to
float to see if they fit to be consumed. When to
introduce water stays on the surface, is a
symptom that is very out of date .
Better wash them when you get home or
before eating? The answer is clear: "We must
save them without having washing. If you wash
and then store, external pollution contaminate
diluted inside the egg. "
And, finally, what to do with those eggs
that come in the package with small
cracks? Maria del Mar clarifies that these
should not consume after the best before date
on the package, but if we use them to cook, we
can ingest them.
