what is chinese egg drop soup made of
Egg drop soup Egg drop soup (traditional: 蛋花湯; pinyin: dànhuātāng; literally "egg flower soup") is a Chinese soup of wispy beaten eggs in boiled chicken broth. Condiments such as black pepper or white pepper, and finely chopped scallions and tofu are optional, but commonly added to the soup. The soup is finished by adding a thin stream of beaten eggs to the boiling broth in the final moments of cooking, creating thin, silken strands or flakes of cooked egg that float in the soup. Egg drop soup using different recipes is known to be a simple-to-prepare soup in different East Asian and Western countries.
Eggshell The bird egg is a fertilized gamete (or, in the case of some birds, such as chickens, possibly unfertilized) located on the yolk surface and surrounded by albumen, or egg white. The albumen in turn is surrounded by two shell membranes (inner and outer membranes) and then the eggshell. The chicken eggshell is 95[citation needed]-97%[1] calcium carbonate crystals, which are stabilized by a protein matrix.[2][3][1] Without the protein, the crystal structure would be too brittle to keep its form and the organic matrix is thought to have a role in deposition of calcium during the mineralization process.[4][5][6] The structure and composition of the avian eggshell serves to protect the egg against damage and microbial contamination, prevention of desiccation, regulation of gas and water exchange for the growing embryo, and provides calcium for embryogenesis. Eggshell formation requires gram amounts of calcium being deposited within hours, which must be supplied via the hen’s diet.[1]
