The egg, a protein-rich food, is very nutritious and its cooking is very easy and fast. It is used in many diets, thanks to its benefits. Eggs are a source of choline, this substance helps promote the proper functioning of the brain.
Contrary to certain beliefs, eggs do not present any danger to your heart, it is possible to consume them but in moderation.
If you eat eggs very often, you probably noticed a small white thread inside the egg. It is called chalaza, a filament that allows the egg yolk to be attached or suspended and held in the center of the white. It also gives us indications on the freshness of the egg, the thicker the egg is fresh. So if you find these filaments in the eggs, do not throw them away!
Zoom on the structure of the egg:
Among the components of the egg are: shell, membrane, white (albumen), yellow (vitellus) and chalaza.
The shell: it is the envelope covering the egg, it is composed of carbonates, phosphates of calcium and magnesium. It is able to ensure the exchange of gases through its pores while limiting the penetration of microbes.
Membrane: It is just below the shell, it surrounds and allows the egg yolk to stand in the center of the egg. In fact, there are two membranes superimposed inside the egg, one that sticks to the shell and the other surrounds the white. When the egg is laid, the membrane separates from the shell and begins to create an inner tube in the lower part of the egg. If the membrane is resistant, be aware that the eggs are fresh.
The white of the egg: otherwise called the albumen, it represents almost two-thirds of the weight of the egg. Composed mainly of water, proteins and minerals, it plays the role of protector of the yellow.
Yellow: it constitutes one third of the weight of the egg. The yolk is rich in minerals, vitamins and proteins. We sometimes find yellows with different colors, this is directly related to the feed consumed by the chicken.
The chalaza : it is a pair of white ropes wrapped, which serves to hold the yellow in place. Sometimes you can find black spots near the chalaza they pose no danger. They usually occur as a result of the rupture of a blood vessel during the formation of the egg.
