The formation process and production principle of sand-peeled eggs

Sand-peeled eggs, also known as "stuffed preserved eggs" and "curved preserved eggs", are a special pickled food, and its formation process and production principle have attracted much attention. Let's learn how sand-peeled eggs are formed.

First of all, the formation of sand-peeled eggs is inseparable from duck eggs, salt, tea leaves and lime. The process of producing sand-peeled eggs can be simply divided into several steps: drilling, pickling, drying, wrapping, and drying again.

Formation process

1. Punch holes: Select fresh duck eggs and use a sharp object to punch small holes in the eggshells to allow the egg white to penetrate. This will allow you to make sand-peel eggs with a delicate texture and delicious taste.

2. Pickling: Soak the beaten duck eggs in a marinade containing tea leaves, salt, lime and other ingredients for a period of time to allow the marinade to fully penetrate the eggs and pickle them into salted eggs.

3. Drying: The pickled eggs must be dried in the sun. This process can make the pickled egg skin harden and form a layer of sandy substance on the surface, hence the name "sand-peeled eggs".

4. Foreskin: After drying, the eggs will have a layer of yellow sandy skin covering the surface. In order to preserve and make them look beautiful, the eggshells can be foreskinned, that is, covered with soil or yellow mud.

5. Dry again: After drying for a period of time, the sand-peel eggs are ready.

Production principle

The formation principle of sand-peeled eggs is mainly to use the salt and lime in the pickling to penetrate into the duck egg through the small holes on the eggshell, making the protein and yolk more delicious. The pickling process can also inhibit the growth of bacteria and ensure food safety.

By understanding the formation process and production principles of sand-peel eggs, we can better appreciate this delicacy and enjoy it with more confidence.
