Some people also lamented

I can't eat it at all

So

What is this "live bead"?

Can I eat it?

Let’s watch together

…

What exactly are live beads?

The so-called "live eggs" are actually chicken embryos that have been incubated from healthy breeding eggs in non-poultry epidemic areas for 12-13 days.

Because this embryo looks like a pearl under transillumination, it is called a "live pearl".

What is the difference between live pearls and hairy eggs?

Live eggs are different from hairy chicken eggs and wedding eggs. Hairy chicken eggs and other "eggs" are chicken (duck) embryos that have failed to hatch and are dead.

In terms of appearance, live pearls are generally hairless or have only a small amount of fine hair, while hairy eggs have more hair. Live pearls will have a protein lump, while hairy eggs generally do not.

It is worth noting that raw eggs are a type of food that poses a food hygiene risk. Article 25 of the Animal Immunization Law clearly stipulates that foods such as raw eggs whose cause of death is unknown cannot be sold.

Can live pearls be eaten?

During the growth and development of chicken embryos, the content of nutrients such as protein, various mineral elements (calcium, phosphorus, etc.), vitamin E, vitamin B1, etc. increases. However, there are no magical nutrients and effects as mentioned in popular rumors. We must look at it scientifically.

"Live eggs" are the product of eggs incubated to a certain stage. No so-called harmful substances are produced during the entire process. Theoretically, they are completely edible. The incubation process of the eggs requires appropriate temperature and humidity, but these conditions are also suitable for the growth of bacteria and other substances. If the hygiene and cleanliness of the environment cannot be guaranteed, harmful substances such as Salmonella will easily appear, posing a health threat to the body.

To sum up, if the live pearls are completely cleaned and fully heated, they can be eaten safely. The live pearls sold on the street have a greater safety risk and are not recommended. If you dine out, it is recommended to choose large, chain restaurants, which have a higher safety factor.

In addition to the above points, there are also rumors that "loose yolk eggs must not be eaten, they are eggs infected by bacteria and other microorganisms", "eggs with spots on the eggshell are infected with harmful microorganisms such as Salmonella, and eating them will cause poisoning", etc. So are there any scientific basis for these statements? Let's continue reading...

Are “loose yolk eggs” eggs infected with bacteria?

Such a statement is too one-sided.

In fact, there are many reasons for the occurrence of "loose yolk eggs":

1. Mechanical yellowing

The eggs were subjected to severe shock during transportation, causing the yolk membrane to rupture.

2. Fertilization and yellowing

After a period of incubation, the yolk of a fertilized egg may become loose.

3. Storage of loose yellow

As eggs are stored for a period of time, the egg white becomes thinner and water gradually penetrates into the yolk, causing it to expand and break the yolk membrane, resulting in the yolk becoming loose.

4. Yellowing caused by microorganisms

Bacteria and other microorganisms invade the egg through the pores in the eggshell, causing the yolk to loosen.

On the premise of ensuring safety and quality, the first three types of "loose yolk eggs" can actually be eaten safely after being heated thoroughly; however, loose yolk eggs caused by microbial contamination are inedible.

If you are not sure why the yolks of your eggs are loose, it is recommended that you do not eat them to be on the safe side.

Can you eat spotted eggs?

Spots on eggs are just a manifestation of eggshell abnormalities, which are related to many factors, but not directly related to salmonella infection. Spots on eggs may be related to the hen's estrogen secretion, nutritional intake, egg cleaning, storage environment, disease and other factors.

Therefore, it is not scientific to judge that eggs are infected with Salmonella simply because they have spots on them. Please do not believe it blindly.

Which other eggs are not edible?

1. Uncooked eggs

Eggs must be heated to above 71°C to fully kill Salmonella, but the coagulation temperature of eggs is around 65°C (egg white is around 62°C, and egg yolk is around 68°C). Therefore, half-cooked eggs are prone to contain harmful substances such as Salmonella, which can easily induce food poisoning after consumption.

2. Spoiled eggs

If you find that the eggs are spoiled or smelly, do not eat them.
