There is a super ingredient, which is available in every kitchen, very cheap, can be bought all year round, and the nutritional value is far beyond our imagination, it is-
Egg
"High-end ingredients often only require the simplest cooking"
There will be soft-hearted eggs, hot spring eggs, and sun eggs......
Of course, there are also those that don't need to be cooked
"Raw eggs" or "sterile eggs"......
Compared to regular eggs
The price of "raw eggs" is much higher
Are "sterile eggs" really completely sterile?
Will the nutrient content be higher?
Can I eat it with confidence?
Note! "Sterile eggs" are not completely sterile!
"Raw eggs" is a process in which the production enterprise controls the production, packaging, transportation, storage and other links that may be infected with bacteria, and then uses pasteurization and other processes to achieve the "sterile" state of the egg.

"Sterile eggs" are eggs that limit the amount of bacteria in the eggs to strict standards and are not completely sterile. Strictly speaking, it should be called "less bacterial eggs".
The bacteria that "sterile eggs" do not have are mainly Salmonella
Salmonella is a common pathogenic bacteria in meat, eggs and milk, which is afraid of heat and cold, has strong low temperature resistance, and can survive in the refrigerator for 3~4 months. When the ambient temperature reaches 100°C, Salmonella dies directly.
Consumption of raw or undercooked eggs is one of the main sources of infection in foodborne illness incidents caused by Salmonella.
Salmonella infection may present with symptoms such as acute fever, abdominal pain, diarrhea, nausea, chills, vomiting, and blood in the stool. Sometimes it lasts from a few days to a week, and diarrhea can last up to 10 days.

The current food safety standards do not require microbiological indicators for ordinary non-ready-to-eat eggs, and only have limited requirements for Salmonella that can be eaten raw.
Therefore, ordinary raw eggs cannot be eaten raw, and soft-boiled eggs such as soft-boiled eggs are not recommended to be eaten.
Is it true that "raw eggs" are risk-free?
It depends on the whole process of egg production, processing, storage, circulation and consumption, covering the introduction of varieties, breeding environment, inputs, storage and transportation, sales and other links, these links will have the risk of contamination by pathogenic bacteria such as salmonella and parasites.
In addition, when we buy "raw eggs", we generally buy a dozen to dozens of pieces, and they have to be stored at home for many days to eat, even the freshest "raw eggs" are basically past the "taste period" of raw food, and the hidden danger of raw eating is very large.
Are "raw eggs" more nutritious than regular eggs?
The nutritional value of eggs depends on what the hen eats, that is, the quality of the chicken feed, and has nothing to do with whether it is a "raw egg" or a "sterile egg".
Eggs themselves are rich in high-quality protein, lecithin, vitamin A, amino acids and other nutrients, which has nothing to do with whether they are "raw eggs".
As for nutrients such as selenium, it can also be achieved by adding feed, and it has nothing to do with whether it is sterile or not.
In fact, compared to cooked eggs, raw eggs retain more nutrients such as B vitamins, vitamins A, D, E, and omage-3 fatty acids because they are not heated, but they also retain some trypsin inhibitors, which makes raw eggs slightly less digestible in protein.

What do I need to pay attention to when buying "raw eggs"?
✎ See the implementation standards
- Choose a brand enterprise that follows the "group standard" or "enterprise standard";
- Pay attention to choose merchants who are qualified for cold chain transportation and storage.
✎ See the date of manufacture
Raw eggs have an optimal raw eating period, don't buy too much at once, it's best to eat them within the expiration date.
✎ Pay attention to isolated storage
Raw eggs have higher requirements for storage and need to be stored separately.
