All hens are born, why are there many different skin colors?
Old people often say that red-skinned eggs are more nutritious than white-skinned eggs. Is this true?
Is there a difference between different colored eggs? Why are egg shells different colors? Let's see what American experts say.
Go to the supermarket or the produce market to look closely at the boxes of eggs. You may notice that the eggs are both white and brown, and sometimes even green or blue. But after turning into scrambled eggs or cakes, basically no difference was seen. So, what's so different about these eggs except the color of the shell is different?
This is not the same as flour or rice. Brown eggs are not necessarily more "natural", and white eggs are not bleached. Instead, they were born that way, including blue-green eggs. But regardless of the color of the eggshell, they are actually the same inside. So why are these eggs born of hens, but the "skin color" is different?
Professor Justin Fowler of the Department of Poultry at the University of Georgia explained: "The eggs are different in color, or some are spotted, caused by different hen genes."
"Laiheng chicken is the most important commercial layer chicken in the United States. They lay white eggs. The eggs from Orpington and Rock chickens are brown. Penetrates the entire eggshell, turning the inside and outside of the eggshell into blue. "
Should eggs be stored in the refrigerator or stored at room temperature?
It depends on which country you live in. Some countries, such as Australia, Japan, and the United States, require eggs for sale to be washed. The cleaning procedure can remove Salmonella, but it also removes the waxy protective layer of microorganisms from the egg shell, so it needs to be placed in the refrigerator.
As for domestic eggs, because the shell is not cleaned, it can be stored at room temperature.
If you see bloodshot or dark brown spots after knocking on the egg, don't worry, it's the same as the color of the egg shell. This is the "merit" of the fallopian tube. "Blood spots" originate from slight bleeding from the hen's ovaries or fallopian tubes. Blood penetrates the yolk and is wrapped in the egg, forming a "blood spotted egg". Black-brown spots are epithelial tissue or other foreign matter falling off of the hen's fallopian tubes, which are formed by being wrapped in eggs when egg whites are formed, commonly known as "meat spots".
Whether it is red eggs, white eggs, green eggs, brown eggs, blood spot eggs, meat spot eggs, as long as they are fresh eggs, they can be eaten with ease after they are cooked, and their nutritional value is similar.
