The price is 3 times!This kind of egg is hot, the truth is ...

With the popularity of Japanese cuisine

Many young people are "planting grass" by sterile eggs

Many merchants claim

"Sterile, no fishy yolk, more yellow, can be eaten raw"

Is there really no bacteria from a bacterial egg?

What is the difference between it and the nutritional value of ordinary eggs?

Is it really nutritious and absorbed by eating sterile eggs?

Li Li'an, dean and professor of the School of Animal Science and Animal Medicine, Tianjin Academy of Agricultural College, said: Ordinary eggs are heated through high temperature, and the pathogenic microorganisms contained in them will be killed, so there is no need to excessively pursue sterile.

"Sterile Egg" is actually "less bacteria"

"The so -called sterile eggs generally refer to eggs that have been sterilized and strictly processed." Li Li'an introduced that the bacterial content in this egg is very small, but it is not completely sterile. It is more appropriate to call it "less bacteria eggs".

Salmonella is a common food -based pathogenic bacteria. People, eggs, and milk that people eat daily may have Salmonella. This bacteria are afraid of heat, not cold, and have a strong low temperature resistance, which can survive in the refrigerator for 3 to April.

When the ambient temperature reaches 100 degrees Celsius, Salmonella dies directly.

"Specific sterile egg production companies will control the number of microorganisms from the aspects of chicken seedlings, feed, drinking water, and breeding environment." Li Li'an said that an ordinary egg may need to go through more than 20 processes, and the number of counts must be counted during the production process. The second "small test" can complete the transformation of the sterile egg.

Sterile eggs are better to eat ordinary eggs

Compared with ordinary eggs, the value of sterile eggs is higher, and the price of some boutiques is 3 to 4 times that of ordinary eggs. There are still many consumers who are willing to pay for the "sterile, wake -free, and yellow yolk" claimed by the merchants.

In this regard, Li Li'an said whether the eggs have a fishy smell mainly related to the variety of feed and chicken. If the feed contains rapeseed meal, rapeseed oil, fishmeal or chlorine chloride, there are more fishy smells produced by chickens that eat this feed, and the eggs produced will be heavier.

The shades of egg yolk are determined by the content of fat-soluble pigment in the feed. If you add more lutein, corn vascin or β-carotene to the feed, the color of the egg yolk will be relatively darker.

Li Li'an said, "As far as nutritional value is concerned, sterile eggs are no different from ordinary eggs, and even eating sterile eggs is better to eat ordinary eggs." Some studies have shown that 91%of the protein in boiled eggs can be absorbed by the human body and raw raw. If you eat, this value is about 55%. Because raw eggs contain some protease inhibitors, it will affect the digestion and absorption of protein.

How to choose an egg

In addition to sterile eggs, there are many types of eggs on the market, such as firewood eggs, selenium -rich eggs, grain eggs, DHA eggs, etc. These eggs are also more expensive than ordinary eggs because of the "prefix" in front of the name.

In the face of a large number of eggs, how should consumers choose?

See the production date, it is best to buy eggs produced within 7 days.

"Listening to the sound" picked up the eggs and shaken in the ear. If there was no sound, it would be a fresher egg. If there was a shaking sound in the egg, it was Chen egg.

See if the appearance of the egg is clean and clean, whether there are cracks, unclean or cracking eggshells are more likely to be contaminated by microorganisms.
