Duck egg is very nutritious, especially salted duck egg, which is really delicious. So how to choose and store duck eggs? Today Xiaobian will show you something.
How to choose and store duck eggs
Duck egg is rich in nutrition and can be compared with egg. Duck egg contains protein, phospholipid, vitamin A, vitamin B2, vitamin B1, vitamin D, calcium, potassium, iron, phosphorus and other nutrients. It tastes more oily than eggs, and duck eggs are generally produced in dirty places, so it may cause harmful bacteria. But it can be eaten if cooked for 15 minutes or used for baking. When boiled, the protein turns blue, and the yolk is orange. Only very fresh can be eaten, not suitable for making protein cream.
Selection of duck eggs
1. Look at the color. The pale blue duck egg is basically produced by new ducks, because the ducks are young and strong, with strong egg production, more calcium content, and thicker shell, which is hard to be damaged; the white shell duck egg is produced by the older duck, which is old and weak in laying, so the shell is thin and easy to be damaged. Another kind of duck egg, commonly known as "sand shell" in Wenzhou, has rough and speckled shell, which is easy to be damaged due to its thin shell due to malnutrition. Remember: duck to eat 'old', egg to buy 'new', green duck egg is the first choice of consumers.
2. Listen to the voice. The duck egg, which is commonly known as "iron sound", has no pores, and its skin is particularly smooth. A flick of fingers or a slight bump of two duck eggs will make a slight and sharp sound. This kind of egg is very few, so it's OK to eat it. If you make loose egg or pickle salted egg, it's not OK. The reason is that the duck egg without pores is fresh after a month's salting.
Storage of duck eggs
1. Duck eggs should be stored with the big head up and the small head down, so that the yolk floats up and pastes under the air chamber, so as to prevent microorganisms from invading the yolk and ensure the quality of duck eggs.
2. In summer, duck eggs should be stored in the fresh-keeping room of the refrigerator, so that the reproduction of microorganisms can be inhibited at low temperature; in winter, duck eggs are not put in the refrigerator, and can be kept for about 30 days at natural room temperature. But it should be noted that duck eggs should be eaten as soon as possible after being washed with water. The washed eggs are easy to deteriorate.
How to eat duck eggs
1. When making salted duck eggs, you can first soak the eggs in white wine for a while, then pull them out and sprinkle a layer of salt evenly, then put them in a transparent plastic food bag for sealing, and put them in a cool and dry place. After 10 days, you will be late for delicious salted duck eggs.
2. Don't take out the duck eggs immediately after they are cooked. Leave them in boiling water to cool down slowly. If you eat duck eggs that are not fully cooked, it is easy to induce disease.
