The main component of egg shell is calcium carbonate, the content is about 85%, the protein content is about 17%, and it also contains trace elements: selenium, zinc, copper, iron, manganese, etc.
In traditional Chinese medicine, some doctors use eggshells as medicine to treat diseases, and have achieved good results. many people want to know what the ingredients of eggshells are. Let’s get to know it together.
Details
01
The egg shell contains 85% calcium carbonate and 17% protein. It also contains various elements, such as zinc, copper, manganese, iron, selenium, etc.
02
Eggshell structure can be divided into five layers from inside to outside, the first layer is the shell lining; the second layer is the shell outer membrane; the third layer is the cone layer; the fourth layer is the grid layer and the fifth layer is the shell membrane.
03
The structure of an eggshell is porous, and it is usually porous and breathable to facilitate the metabolism of life inside the shell. “Breathable” means air, including the oxygen in it. Generally, the newly laid eggs have a small air chamber. As the temperature drops, the egg white shrinks, and the air chamber becomes larger. With the increase of storage time, the consumption of nutrients and the evaporation of water, the air chamber will gradually increase. If the egg is a fertilized egg, when the air cell exceeds 1/3, it loses its hatching value.
04
Eggshell can make acid and relieve pain, grinded into powder for external use, can stop bleeding in trauma, solid astringent and astringent. It can be used internally for gastric ulcer and gastritis pain, and is beneficial for calcium supplementation (calcium food). The thin skin lined with eggshell has the function of nourishing Yin and moistening dryness, moistening lung and relieving cough, which is suitable for wind-dry and dry cough.
05
Scientists have found that the thin eggshell can withstand such a large external force because it can evenly distribute the pressure to all parts of the eggshell.
