1, the shelf life of salted duck eggs depends on the environment. Salted duck eggs can be preserved for about nine months at room temperature if they are preserved by themselves. Salted duck eggs preserved in summer are generally kept at room temperature for about three months. If stored in the refrigerator, they can be refrigerated for about twelve months.

2. The preservation method of salted duck eggs is also relatively simple. Generally speaking, it is hot in summer, and duck eggs can be kept in cold storage. Be careful not to freeze them. Frozen salted duck eggs taste bad and can be placed in the cold storage layer.

3. When it is cold in winter, duck eggs can be kept in a dry and ventilated place, so as not to be exposed to the sun, which can prolong the preservation time.

4. Salted duck eggs contain a lot of protein, and protein is decomposed into amino acids after pickling. In addition, after salted duck eggs, the salt content will increase, and the inorganic salts in the eggs will also increase.

The yolk of fresh duck eggs contains a lot of fat. This substance is combined with protein, and no grease can be seen. After curing for a period of time, it will denature and separate from fat, which is the egg butter in salted duck eggs.

6. Salted duck eggs are rich in calcium. After salted duck eggs were salted, the protein content in them would be obviously reduced, but the calcium content would not be reduced.
