About Century Egg
Traditional alkali-treated egg; amber jelly-like white, distinctive taste.
Health Benefits of Century Egg
High protein, easy to digest
Century egg is duck egg treated with alkaline materials (lime, ash). The alkali denatures and sets the protein into a translucent amber jelly white and dark-green yolk. Partial breakdown of protein into amino acids gives its signature savoury, mildly alkaline taste.
Improved protein digestibility
Alkali treatment partly breaks the protein down, making it easier to absorb. 100g has about 14.2g protein, higher than fresh duck egg (12.6g). Minerals such as iron and zinc also dissolve out more readily after treatment.
14.2g protein; pair with tofu for calcium
The commonest use is cold century-egg tofu - soft tofu with soy sauce, vinegar and sesame oil, silky and refreshing. Or chop it into congee for pork-and-century-egg, a Cantonese classic. Choose lead-free products for safety.
