How to recognize better eggs? The color of the yolk says a lot about the freshness and the origin of the eggs. For those who consume eggs, here are some tips to recognize really fresh eggs from hens raised in the open air.

If the egg yolk is yellow, the chickens were probably raised on cheap feed. If instead the yolk is dark orange in color, here we are faced with a egg produced by free range hens.

The doctor says so Hilary Shallo Thesmar, director of food safety programs for the Egg Nutrition Center (ENC). The color of the egg yolk would be due to the pigments present in what the hens eat, in particular the beta-carotene.

Free range hens would have a better chance of feeding on more pigment-rich foods such as carotenoids, which would then determine the color of the yolk. The darker colored yolks would also indicate the presence of omega 3 fatty acids and xanthophylls in the chicken feed.

In any case, according to theEgg Nutrition Center, eggs from farms and eggs from free-range hens have an identical nutritional intake in terms of the amount of fat, protein and cholesterol.

Le free range hens therefore have the ability to eat more richly pigmented foods that make the darker egg yolk. Here then is that the color of the yolk becomes an easy clue to recognize the origin of the eggs.

How to do it understand if the eggs are really fresh? Here is a very simple system handed down by grandmothers and housewives of the past.



Dissolve 25 grams of salt in a jug full of water (one liter) and then immerse the egg:



1) If it rests on the bottom it is very fresh.
2) If it floats on the bottom it is fresh (1 to 4 days).
3) If it floats at the top but without surfacing it is not fresh.
4) If it floats on the surface it is very old, better not eat it!
