Why are Songhua eggs called Songhua eggs?

Songhua eggs, commonly known as "preserved eggs". It has a history of more than 400 years and originated in southern China. There is an interesting legend about its origin.

It is said that there is a river crossing in the south of the Yangtze River and a dense number of lakes and ponds, and there are two husbands and wives living in the river port, and the man's surname is Li. Both husband and wife are over half a hundred years old, and they live by setting up tea stalls, and the people who come to drink tea are some poor fishermen. But this year, it rained heavily, and there was an ocean everywhere.

There are fewer fishermen, and the old couple's business is not good, and life is even more difficult. There was an old duck keeper who gave them a pair of female ducks. They live on the ducks.

The duck lays two eggs a day and is very punctual. But the good times didn't last long, and the duck eggs couldn't be found, and the couple was very upset. One day, when they were cleaning up the tea set, they poured the leftovers into the pine ash pile outside the house as usual.

Suddenly, they saw the duck eggs they had been looking for for a long time, and it turned out that the ducks had laid the eggs in the ash heap of the pine trees. But after the eggs have been buried in the ash heap for so long, and the tea leaves are poured every day, is it already bad? They opened an egg and saw that the white had turned yellow-brown, like crystal.

Duck eggs also have a special fragrance, which is the Songhua egg that we often eat now.

Preserved eggs Preserved eggs, also known as Songhua eggs, eggs, etc., are traditional flavor egg products in China, which are not only loved by domestic consumers, but also enjoy a good reputation in the international market. Preserved eggs are not only a delicacy, but also have certain medicinal value. Wang Shixiong's "Diet Recipe for Living with Rest" says:

Preserved eggs, spicy, astringent, sweet and salty, can diarrhea, sober up, go to large intestine fire, cure diarrhea, can disperse and collect. "Traditional Chinese medicine believes that preserved eggs are cold and can treat eye pain, toothache, high blood pressure, tinnitus, dizziness and other diseases. Edible for all:

Those who are on fire are the best; Children, people with insufficient spleen and yang, dysentery under cold and dampness, cardiovascular disease, liver and kidney diseases should eat less. Precautions: Songhua eggs should not be eaten with soft-shelled turtles, plums, and brown sugar.

Dosage: Songhua eggs should be eaten with minced ginger and vinegar to detoxify; Songhua eggs are best eaten after steaming, and Songhua eggs also contain lead, so it is best for children to eat less. It should not be stored in the refrigerator.

How were the first preserved eggs made? According to legend, during the Taichang period of the Ming Dynasty, a small teahouse in Wujiang County, Jiangsu, the owner would do business, so the business was prosperous. Due to the lack of manpower, the shopkeeper in the entertainment guests, casually poured the brewed tea leaves in the ashes, it is also a coincidence, the shopkeeper also raised a few ducks, love to lay eggs in the ash pile, the owner picks up the eggs, it is inevitable that there are omissions.

Once, when the shopkeeper was removing the ash and tea residues, he found a lot of duck eggs, and he thought that he could not eat the preserved eggs. Who knows that when you peel it off, it is dark and shiny, and there are white patterns on it, and when you smell it, a special fragrance comes to your nose; Taste it, it's fresh and smooth. This is the original preserved egg.

Later, after people's continuous exploration and improvement, the production process of preserved eggs was improved day by day. Another theory says that Songhua preserved eggs originated in Tianjin. Folk word-of-mouth cloud:

About 200 years ago, a wealthy family in a village in Tianjin, his son made a coffin for his mother, and placed it in an empty house for later use. When it's done, forget about it. The following year, when the mother died, the coffin was moved into the coffin, and there were more than 100 eggs in the ashes of the coffin.

The filial son was furious, took out and threw it on the dry ground, and the shell was cracked and the inside had become a dark brown transparent crystal, so it was very confused. Those who have good deeds have the courage to taste it, and the taste is delicious, and the onlookers are also surprised, so they compete to taste it, and it is so. Those who have insight will follow suit afterwards and put fresh eggs in lime and plant ash, and the same is true.

As a result, the neighborhood followed suit and called it a "chameleon egg". Over time, this original process has been spread in Jiangsu and Zhejiang, and has been improved repeatedly, and the process has been perfected day by day, and the color-changing egg as a new food has been pushed into the market by the people of Jiangsu and Zhejiang who are good at doing business. Therefore, today's "Songhua Preserved Eggs" began in Tianjin and became in Jiangsu and Zhejiang.

Because after peeling off the shell, you will see that the egg has a pattern like a pine flower, which is very beautiful; But eating Songhua eggs for a long time is not good for the body, because Songhua eggs are also one of the pickled products.

Because when making, a layer of mud will be smeared on the eggshell, and some lime, salt and other substances will be added, after a long time of pickling, some substances penetrate into the egg, and some substances have a chemical reaction, but the amino acids produced cannot be dissolved, and finally can only appear in the form of crystals, so it also forms the pine flower we see on the preserved egg, and the name of the pine flower egg comes from this.

In fact, they are a kind of thing, that is, the name is different, because in the past, there were only preserved eggs, and later the preserved eggs were good, and if the preserved eggs were done well, there would be pine flower-shaped things on the preserved egg skin, which was very beautiful and tasted, so later someone took the name of Songhua preserved eggs, which was to tell people that the preserved eggs he bought would have pine flowers, and the taste was good, which was the best preserved eggs.

Because after peeling the preserved egg, you can see a white pattern on the surface of the preserved egg.

Introduction: Preserved eggs are a kind of food that we often eat, and there is often cold preserved egg preserved egg lean porridge.

Wait a minute. These foods often appear in our daily life, preserved eggs, and there is also a name called Songhua eggs.

Many people don't understand why preserved eggs are called Songhua eggs, in fact, there is a reason.

1. Preserved eggs, also known as Songhua eggs, when making preserved eggs, people will coat a layer of mud on the outside of the shell, and some alkaline substances will be added to the mud, such as lime or sodium carbonate.

Wait a minute. When these substances are added, they penetrate the inside of the egg through the surface of the eggshell throughout the curing process. After penetrating deep into the inside of the egg, it will be combined with the amino acids in the egg white.

Produce a chemical reaction.

This amino acid salt cannot be dissolved in the egg white, so it will produce crystals on the egg white, which is the pine flower we often see on the preserved egg, which is also the origin of the name of the pine flower egg. <>

Second, the production of Songhua eggsSonghua eggs will be made of soda ash.

Lime, salt, and yellow powder are mixed in a certain proportion and wrapped in mud and bran on the outside of the duck eggs, and the delicious Songhua eggs are made after marinating for about two weeks. Huangdan powder is not lead oxide, the use of huangdan powder, Songhua eggs will be polluted by lead, the state has regulations, the lead content in Songhua eggs shall not be three milligrams. Therefore, most of the Songhua eggs we eat are not lead-free, but the lead content is lower than the national standard.

Of course, there are also some unscrupulous businesses who will ignore the national standards and exceed the lead content after making Songhua eggs. Therefore, everyone should pay attention to the lead content when buying Songhua eggs, and do not buy Songhua eggs with excessive lead content. <>

3. Those people are not suitable for eating Songhua eggs because Songhua eggs contain a certain amount of lead, so they are like babies or have insufficient spleen yang and cardiovascular disease.

patients try not to eat, or eat less. Even adults should pay attention to the dosage when eating Songhua eggs, don't use too much at one time, otherwise it will have an impact on the body, and it doesn't matter if you eat less.

When making preserved eggs, a layer of mud will be smeared on the shell of the egg, and some alkaline substances will be added to the mud, such as lime, sodium carbonate, etc., during the curing process, these substances will penetrate into the interior through the tiny pores on the surface of the eggshell, and chemically react with the amino acids in the egg white to produce a certain amino acid salt. However, amino acid salts cannot be dissolved in the protein, and will be precipitated in the form of crystals, which looks very similar"Pine flowers"That's how Songhua Egg came about.

The egg white of the pine flower egg neutralizes the surface of the egg yolk, and there are needle-like crystals formed, which are called pine flowers, especially the 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.

Because when you cut the preserved egg, you can see some pine flower-like crystals inside, so it is called this name. There's a reason, of course, and it has to do with the way it looks.

Mainly because when making preserved eggs, a layer of mud will be smeared on the outside of it, and some lime and carbonic acid will be added, and crystals will appear in the end, so it is particularly like pine flowers, and finally there is a title such as pine flower eggs.

Preserved eggs are also known as pine eggs, mainly because snowflake-like patterns sometimes appear on the surface of preserved eggs, and for this pattern, some places are called "pine flowers", which is the reason.

Because when pickling preserved eggs, its protein will have some crystals, which looks like pine flowers, so it is called pine flower eggs.

Because the shape of the preserved egg is very similar to the pine flower after opening, it is called the pine flower egg, and the preserved egg is particularly delicious, and many people like it.

It is because most people call preserved eggs, and in the traditional sense there is a good name called Songhua eggs, so education is because of a habit that people have eaten for a long time, he has such a saying.

It was he who made it in the process of making it, and its appearance was very similar to that of a pine flower, so he gave it such a name. It's called only because of its appearance.

This is because during the production process of preserved eggs, there will be a layer of gray on the outside, and there will be some patterns on it, and the whole is relatively dark, giving people a special feeling like snowflakes.
