It is said that the custom of laying eggs has a history of more than 4,000 years.
However, a little expert in life like Dr. Clove basically only cares about whether the eggs will stand up in one case:
- If an egg can be straightly laid sideways, it means it is relatively fresh. If the big head is slightly tilted and tilted like the above picture, it may be several days. If the small head is up and the big head is up, it may be two or three weeks. If the whole egg leaves the bottom of the bowl and floats up: this egg is not fresh.
Is it very good? Unfortunately, when buying eggs, no boss will let you try them one by one.
You must have heard many other tips for choosing good eggs, but guess how many are right?
Is red-shelled eggs better than white-shelled eggs?
How can one lay eggs by appearance?
Eggshell colors are red, white, deep and light, just as our skin is yellow, white and black. It has nothing to do with the nutritional value of eggs.
Whether it is a what-colored shell, the nutrition of eggs is similar.
What’s more, the eggshells have been peeled off, and we don’t chew the eggshells to eat, which is really useless.
Is it better to have a dark yolk?
How can one [again] lay eggs by appearance?
The main nutrition of eggs still lies in protein, fat, vitamins and minerals.
Lutein in chicken feed, which mainly affects egg yolk color.
But listen to the name also know, we mainly rely on eating leafy vegetables to obtain lutein. Therefore, its impact on the overall nutrition of eggs can generally be ignored.
Farmers may add more yellow corn to chicken feed, or chili powder, carrots, pumpkins, orange peels and alfalfa, which will be more expensive to sell if they seize everyone’s psychology of buying dark egg yolks.
But in case one does not control… individual farmers illegally use red pigment in the feed processing industry, the egg yolk will be exceptionally red, which will become the problem of the past [red egg].
Therefore, we should remind everyone that:
Egg yolk is darker and not necessarily more nutritious, but it will definitely be more expensive and may have certain safety risks.
Is it better for native eggs and free range eggs?
Don’t be in a hurry to tell Dr. Clove that native eggs really taste more delicious, and ordinary eggs don’t taste like eggs.
It is very possible that there is a difference in taste, which can be admitted, but which is better to eat has a lot to do with the variety of chicken.
However, there is no significant difference in nutrition between native eggs (free-range eggs) and raised eggs on the whole.
However, native eggs lack sterilization technology, which makes them more likely to be contaminated by bacteria and eat bad stomachs.
The production of native eggs is small and they are expensive to sell, which does not mean they are more nutritious… Of course, the rich and their friends who raise hens, please feel free.
Is organic eggs better?
The word “organic” sounds like a high-grade feeling with its own halo.
However, organic products are only more strictly controlled in the production process, more strictly controlled in the use of chemicals and the selection of sites, and the production, processing and sales should be certified by government agencies.
Organic eggs will not be more nutritious than ordinary eggs, nor will they be safer than any qualified egg product, but they must be much more expensive.
Therefore, the principle of selecting good eggs is very simple, and the key is two points:
-
Choose the fresh ones: you must put them in the refrigerator for refrigeration as much as you eat and buy.
-
Buy cheap: the nutrition is the same anyway.
