I remember eating moon cakes during the Mid-Autumn Festival on August 15th. Many people like to eat moon cakes with salted egg yolks. In addition to moon cakes and pies, the salty egg yolks can also be used as cooking foods. Salty egg yolks generally refer to salted duck eggs. Salted duck eggs are called salty dumplings, salted duck eggs, salted duck eggs, and green fruits.
The salted duck has a long history. In the Qi Min Yao Shu when it was in the Southern and Northern Dynasties, it was described in the book: “Dip the duck in January, cook it and eat it, and use it for wine and food.†It is talking about salted duck eggs. In the Qing Dynasty, there were already many workshops processing salted duck eggs, and the most famous salted duck eggs from Jiangsu Gaoyou.
The salted duck eggs are made from fresh duck eggs. Different methods are used in different places. Some use salt water, some use yellow sand, and some use batter, and even white wine. The taste is also quite varied. In addition to ordinary salted duck eggs, spicy and salted duck eggs can also be produced.

From the original 11.6 g to 13.1 g, the content of sugar compounds also increased, from the original 1.6 g to 10.7 g, and the calcium content from the original 55 mg to 512 mg, the sodium content Do not say, after all, is soaked in salt water, sodium content will certainly be greatly improved.
The effect and role of salted duck eggs
In traditional Chinese medicine, salted duck eggs are cool, can nourish yin, moisten the lungs, remove heat, and have a better effect than the fresh duck eggs. And the high calcium content of salted duck eggs, so the salted duck eggs can be used to supplement calcium, and the iron, calcium and inorganic salt in the salted duck eggs are better than fresh duck eggs, so the right amount of food is harmless and beneficial, but Because the sodium content of salted duck eggs is very high, excessive consumption of salted duck eggs can lead to excessive sodium, which may lead to high blood pressure and other health hazards.
Why is there so much oil in the salted duck's egg yolk compared to fresh duck eggs?
The first thing to say is that even fresh duck eggs contain 14% to 16% of fat, which is relative to the entire duck's egg. If you remove the protein and only count the content of fat in the egg yolk, then the content of fat in the egg yolk is probably 31%-36%, so that is one third of an egg yolk is fat.
While we usually boil duck eggs, duck eggs also contain protein, protein is a good emulsifier, will be divided into small droplets of fat in the egg yolk, so that people can not tell the naked eye, and salted duck eggs to After soaking in salt water, salt penetrates into duck eggs and causes salting-out reaction with protein, which causes denaturation and coagulation of proteins. After the action of the emulsifier protein, the small oil droplets encased in it are polymerized and become salted egg yolks. Visible grease.
