Why does there grow hair in preserved eggs? Why do eggshells grow hairy

I don't know if you like to eat preserved eggs? Anyway, I like to eat preserved eggs very much, because the taste of preserved eggs is very special. In fact, preserved eggs are generally called by southerners, and northerners generally call preserved eggs Songhua eggs.

This is because the best preserved eggs will have pine flowers inside. These pine flowers bloom on preserved eggs and are very beautiful. But some people who don't know still think that the preserved eggs have white hair, but in fact, the so-called hair on the preserved eggs is pine flowers.

People in my hometown believe that in order to make preserved eggs full of pine flowers, it is necessary to make pine eggs from the ash of burning pine branches. However, technology has proven that the reason why preserved eggs are covered with pine flowers does not have to be made from pine branches. The reason why people think this is because the ash from the pine branches is alkaline, so it is believed that the ash from the pine branches can be used to make preserved eggs into preserved eggs full of pine flowers.

Nowadays, people don't use the ash burned from pine branches to make preserved eggs, and they generally use white ash. White ash is as alkaline as ash from fired pine branches. When the egg is coated with a layer of white ash, because the white ash is strongly alkaline, the hydroxide ions in the white ash.

will pass through the shell of the egg.

into the egg. The hydroxide ions that enter the eggs will be combined with some proteins and amino acids in the eggs.

A chemical reaction is carried out, and finally amino acid salts are formed. The amino acid salts will crystallize on the surface of the preserved eggs, and finally form beautiful pine flowers. Therefore, it is generally believed that preserved eggs with pine flowers are good preserved eggs.

Because preserved eggs are formed by the reaction between eggs and alkali, preserved eggs will taste a little astringent. But that doesn't stop it from being loved by people at all. The home-cooked way to eat preserved eggs is cold salad, cut a few preserved eggs, and mix them with cucumber shreds.

There's really nothing to say about that taste. The nutritional value of preserved eggs is also quite high, because the amino acids, proteins and alkalis in eggs react and become small molecule compounds. This is more conducive to our body's absorption.

Not only that, but the cholesterol of preserved eggs.

The content is also greatly reduced, so the elderly can also eat preserved eggs with confidence.

In the production process of pine eggs, some alkaline substances will be added, and some proteins in poultry protein will be decomposed into amino acids, and the two will be mixed to generate amino acid salts, forming geometric crystals.

Because when making preserved eggs, a chemical reaction occurs in them, resulting in pine flowers, and these hairs are pine flowers.

It is because there is a certain chemical reaction in the preserved egg, so it grows hair.

That's not the real hair, the preserved eggs in the pickling process formed by the unique pine flowers, preserved eggs are also called pine eggs, and some places will judge the quality of preserved eggs according to the pine flowers.

The causes of hair growth in the shell of eggs can be roughly classified into two categories: one is caused by the dampness of the egg, such as placing it in a place with high relative humidity, such as in the refrigerator. The air humidity is high, and the food placed at home is also very easy to mold; The other type is to put the already moldy and hairy food and eggs together, resulting in eggs also hairy and moldy, this mold is more common with aflatoxin, and its long hairs are a large number of hyphae multiplying and intertwined into villous, flocculent or reticulated and other manifestations.

Can you still eat an eggshell with hair: You can't eat it. Eggshell hair is actually moldy, and mold poison stool dry is diffusible, will gradually pollute the egg white, egg yolk breeds a large number of bacteria and mold with the small pores on the surface of the eggshell, resulting in the whole or even the whole batch of eggs are moldy and deteriorate, usually the eggs infected by mold inside the naked eye can not be seen abnormal, but eating is extremely harmful to the body, so the eggs with long hair must not be eaten.

1. Eggs will come out because they are moldy.

2. Under normal circumstances, the surface of the egg should be smooth and free of foreign matter, and some farmhouse eggs may have residues such as chicken feces on them, but if the eggs are bought for a long time, there is a phenomenon of long hair, indicating that the eggs have suffered from mold invasion and have become moldy and deteriorated. And the same batch of eggs that are stored in the same period should also be checked, if there is mold and yellowing, they can no longer be eaten.

And the same batch of eggs stored in the same period should also be checked, if there is mold, yellowing, can no longer be eaten.

1.Introducing hairy eggs.

Hairy egg is a marine mollusk belonging to the persimmon snail family, which is mainly distributed in the East China Sea, South China Sea, Yellow Sea, Bohai Sea, and the surrounding waters of Japan and South Korea. Its shape is oval, there are many small protrusions on the surface of the shell, the two ends are rounded, and the middle is slightly contracted, which looks like eggs, so it is named "hairy eggs".

2.Appearance features.

The surface of the shell of the hairy egg is hard and smooth, brown or yellowish in color, sometimes with irregular brown spots. It has many small protrusions on the surface of its shell, some of which are slightly raised, and some of which are spike-shaped. Inside the mature hairy egg, there is an egg-yolk mollusk that can be steamed or eaten raw.

Although the hairy eggs are a little rough on the outside, in the early stages of floating and planktonic life, a small paraffin worm is embedded in the surface of their shell, which protects their body surface.

3.Growing environment.

Hairy eggs are shallow sea creatures that usually grow on rocks on the bottom of the sea at depths of 10-20 meters, or on sandy areas where the sea rolls up to a large extent. They usually grow in a rich environment, where they can find a large number of benthic organisms, small shellfish and plankton on the seafloor, and the abundance of food is the main reason for their growth and shell health.

4.Nutritive value.

The meat of hairy eggs is delicate, fragrant, rich in a variety of amino acids, proteins, fats, calcium, phosphorus and other nutrients, and is known as a treasure in marine food. In addition to being rich in high-protein nutrients, hairy eggs are also rich in a variety of natural active substances, such as polysaccharides, protein enzymes, etc., which are not only beneficial to the body's immunity, but also promote metabolism.

5.Cooking method:

Hairy eggs are an extremely delicious seafood dish that can be cooked in many different ways. One of the most classic is steamed hairy eggs, in addition, it can also be baked, fried, boiled, stewed and other ways to cook and match. Before eating hairy eggs, you need to rinse them with water to remove impurities and sediment on the surface, and then blanch them in boiling water to remove odors and mucus to make them more tender and delicious.

6.Origin and**.

The production of hairy eggs in the southern region of China is relatively high, especially in Guangdong, Hainan and other places, and it is one of the main foods of local residents. Due to its long growth cycle, it is relatively expensive, and most of the products on the market are about 50 yuan per catty. In addition, in the coastal areas of Japan and South Korea, hairy eggs are also a very popular seafood food.

Of course, you can eat it, it's a pine flower that grows on the egg white.

How did the pine flowers on the preserved eggs come about?

In fact, it is produced by a chemical reaction: the main chemical component of the protein is a protein. When eggs are left out for a long time, some of the proteins in the egg whites will break down into amino acids.

Its chemical structure has an alkaline amino-NH2 group and an acidic carboxyl-COOH group, so it can interact with both acidic and basic substances.

Therefore, people are making Songhua egg designs, and deliberately add some alkaline substances to the mud. Such as lime, potassium carbonate, sodium carbonate, etc. They pass through the pores in the eggshell and combine with amino acids to form amino acid salts.

These amino acid salts are insoluble in protein, so they crystallize in a certain geometric shape to form beautiful pine flowers.

Maybe it's hairy eggs. There are chicken feathers in it, it is not very hygienic, the pine eggs are burned with lime and then brewed, it is not easy to digest, it contains alkaline, it is still less to eat when defecation, and it is easy to cause cancer if you eat more, especially for children.

Hello, in the egg white and the surface of the egg yolk of the pine egg, there are needle-like crystals formed, called pine flowers, especially high-quality products, which are full of pine flowers. But how exactly is the pine flower formed? Some people think that it is the reaction of cypress branches, and the ash from the burning of pine branches into the egg, while others think that it is a skill"Clever hands out of pine flowers"In fact, this is all a misunderstanding.

Practice has proved that pine flowers can also be formed without cypress branches and pine branches. In recent years, it has been proved that pine flowers are mainly formed from magnesium salts, and also contain some free amino acid crystals. Therefore, how much Songhua marks the quality of Songhua eggs, people are known"The eggs are good and the flowers are loose, and the flowers are good for the preserved eggs"This indicates that Songhua eggs are the characteristics of high-quality preserved eggs.

Preserved eggs are also known as Songhua eggs in Beiping, because after being made for a long time, the egg white part has a needle-like pattern like pine leaves, so it is named. This is because after the protein is broken down into amino acids, when there is less water and the temperature in the north is low, crystals are formed, which some people call the crystals of dry tyrosine.

Because the flowers on the preserved eggs are artificial.

One. The main raw material of Songhua eggs is duck eggs, in addition, soda ash, lime, salt, tea, yellow powder, plant ash, pine and cypress branches, etc.

1. The choice of duck eggs.

Processed Songhua eggs must use high-quality fresh eggs in order to meet the quality standards of high-quality products.

2. Materials and their functions.

The materials used in the processing of Songhua eggs must also meet the quality requirements in order to make high-quality and standard-compliant Songhua eggs.

Second, the processing principle.

1. Features. The prepared Songhua egg, the eggshell is easy to peel off, the egg white is coagulated, it is light green-brown or brown translucent jelly-like, there are pine needle-like white crystals or patterns in the brown egg white, the egg yolk is semi-coagulated, the egg yolk can be clearly divided into different colors such as dark green, earth yellow, gray green, orange yellow, etc., and there is soup in the egg yolk. The finished product has a unique flavor, rich fragrance, little spicy taste, and a cool feeling after eating.

2. Processing principle.

Fresh duck eggs can be made into pine eggs with the above characteristics, which is due to the formation of duck egg contents under the comprehensive action of various materials during the transformation process. The main role is played by sodium hydroxide, which gradually leaches into the protein during processing, causing the protein to coagulate.
