Bastillepost · 1 SOURCESabout 3 hours ago2 MIN
Summary
Century eggs, known for their distinctive dark green color and jelly-like texture, have long been considered an exotic and polarizing food item. Foreign media once ranked century eggs among the "world's most disgusting foods," with bizarre rumors claiming they were made with horse urine. However, historical records and food science reveal a far more interesting story of accidental discovery and traditional preservation wisdom.
Key Points
- The origin of century eggs is traced to a Ming dynasty tea shop in Hunan province, where a proprietor discovered duck eggs left in tea ash had developed into a unique delicacy with translucent brown protein resembling jelly
- Traditional production methods use quicklime, wood ash, salt, and tea to wrap eggs, creating an alkaline environment that causes proteins to solidify and extend shelf life without refrigeration
- During fermentation, egg proteins decompose into smaller amino acid molecules that are more easily digested and absorbed by the human body
- Century eggs contain nutritional benefits including iron, zinc, vitamin B12, and various minerals, though their high sodium content means moderation is advised
- In traditional Chinese medicine, century eggs are believed to have cooling properties that help reduce internal heat and nourish yin and fluids
