Are the ‘red dots and white strings’ visible on eggs safe to eat?

Raw eggs are often eaten with dishes like yukhoe, bibimbap, or ramen. Sometimes, red spots or white strings are found on the raw eggs; is it safe to eat them?

 

◇ Red spots, harmless blood stains

 

The red spots on raw eggs do not affect your health, so it is safe to eat. These red spots are called 'blood spots.' Blood spots are traces that appear on the surface of the yolk when microvessels in the ovary rupture while the egg is forming in the fallopian tube.

Blood spots mainly occur when chickens are exposed to high-temperature environments or are under stress.

Chicken breed, aging, and excessive activity during ovulation can also be causes. In fact, about 30% of older hens lay eggs with blood spots. Although blood spots may look unsightly, they are not foreign substances, so they pose no health risks if cooked thoroughly.

◇ White string, a lump of high-quality protein

 

The long, white string visible when you crack an egg is called the 'chalica.' Located next to the yolk, the chalaza holds it firmly in place to keep it centered. The chalaza is often mistaken for a lump of fat or cholesterol, but

In fact, the chalaza is a mass of high-quality protein.

Egg membranes are rich in a protein enzyme called 'lysozyme'. Lysozyme is an antibacterial component used in pharmaceuticals and food preservatives, and it also helps eliminate Salmonella.

The chalaza can be bothersome, but the fresher the egg, the more distinct the chalaza is.

 

◇ Freshness can be checked by the skin and sound

 

Meanwhile, freshness can be easily determined without cracking an egg. Fresh eggs have a fine, smooth shell with a glossy sheen. Also, they do not make a sound when shaken.

 

In addition, freshness can be checked through egg grading. Egg grading classifies quality into grades 1+, 1, 2, and 3 based on the freshness and condition of the contents.

 

When storing eggs, you must put them directly in the refrigerator to maintain their freshness.

 

In this case, store it in the back of the refrigerator with the rounded side facing upward. It is best to keep it refrigerated at a temperature of around 0 to 4 degrees Celsius.

 

 

 

=========================

If there are membranes, does the freshness decrease?

I was thinking this,

It's a lump of protein.

 

Storing eggs is important, isn't it?

I always buy the second edition.

I boil four every day and eat them with my husband.

 

Make sure to store it in the back of the refrigerator.

Not in front of the door.
