The nutritional value of salted duck eggs
1, amino acid
Duck eggs contain a large amount of protein, and this substance is decomposed into amino acids during the salting process. In addition, the salt content in salted ducks leads to an increase in the salt content of the duck eggs. As a result, the inorganic salts in the eggs also increase slightly. In fresh duck eggs, the fat in the egg yolk does not contain fat because it binds to proteins, and the protein denatures and separates from the fat by pickling for a while, and the fat in the duck eggs gathers together. It became egg butter.
Salted duck egg yolk contains a large amount of red and yellow yolk and carotene, and is dissolved with egg butter so that we can see the red and yellow. Salted eggs are the signs that salted eggs have been marinated. It can be said that the nutritional value of salted duck eggs is very high, and there is not much difference between the nutrition contained in fresh duck eggs.
2, rich calcium
After the duck eggs are salted and made into salted eggs, the protein content contained therein will be significantly reduced from 10.7 grams per 100 grams of fresh eggs to 10.4 grams. At this time, the amount of fat contained therein increased significantly, from 11.6 grams per 100 grams of fresh eggs, to 13.1 grams. Not only that, the carbohydrate content in salted duck eggs also increased significantly, from 1.6 grams per 100 grams of fresh eggs, to 10.7 grams.
The most important thing to mention is the preservation of minerals. The minerals contained in duck eggs will not be damaged during the process of salting, and it will also allow calcium to be greatly improved in the process of salting. From 55 grams per 100 grams of fresh eggs, rose to 512 milligrams.
3. Inorganic salt
In salted duck eggs, in addition to rich in calcium, but also contains iron, phosphorus and other inorganic salts, and experts found that salted duck eggs contained calcium, iron quality than eggs, fresh duck eggs are higher. Therefore, their nutritional value is basically the same as their respective advantages. Proper eating does no harm to the body and therefore can be eaten with ease in everyday life.
Although the nutritional value of salted duck eggs is high, and no amount of harm is caused by proper consumption, no food can be eaten any more. For example, the salt content of salted eggs is generally around 10%. If it is eaten excessively, it will probably result in high food intake. Blood pressure, thereby seriously endangering the health of the human body.
4. Clear Lung Fire
Through research, it has been found that various nutrients contained in salted duck eggs have good effects such as nourishing yin, clearing the lungs, enriching muscles, and skin. Therefore, it is very suitable for eating in the summer. In addition, Chinese medicine practitioners in our country believe salted duck egg whites have better lung function and lower negative fire than salty egg butter, which can cure children's food. External application can cure burns and eczema.
The nutritional value of salted duck eggs is very high, so we may wish to eat more in daily life. However, since salted duck eggs contain a lot of fat and oil, people with high blood lipids should eat less.
Why salty duck eggs turn black
Although salty duck eggs are not easily spoiled, they must be protected from water loss during storage. Once the salted duck eggs lose water, the protein will be black and the salinity will increase.
Can not eat, after the eggs are cooked, as the bactericillin in the egg white is gradually reduced, the cracks or invading bacteria multiply through the shell pores to produce methane, nitrogen, ammonia, carbon dioxide and other substances, and then the egg meat slowly loosens. Will shake, an egg is really not much money, so, if safe, still do not eat ..... and the unripe egg yolk eaten after overnight, in the case of improper preservation, nutritious things are easy to breed bacteria, so It can also be harmful to health. And the nutritional value of overnight things has been greatly reduced, because many nutrients have been broken down after the bacteria have grown, and the aforementioned substances such as methane, nitrogen, ammonia and carbon dioxide have been generated. One of the reasons why children eat overnight eggs and milk. Another point is that pickled foods contain nitrite, a carcinogenic substance that should be eaten in moderation!
The benefits of eating salted duck eggs
The function of salted duck egg white lung fire and negative fire is better than that of unsalted duck eggs. Cooking can cure diarrhea.

Salty duck eggs or eat less as well, because salted duck eggs with high salt, high blood pressure, diabetes patients should not eat more.
And because the main raw materials used for processing salty duck eggs are duck eggs and salt, there are some informal processing points that pursue low cost or to shorten the production cycle, the quality of the used salt cannot meet the requirements of the relevant standards, and the cesium chloride in the inferior salt Harmful substances such as nitrite will penetrate into salted duck eggs. It poses a threat to human health.
