Understanding Preserved Duck Eggs (Century Eggs)

Preserved duck eggs, also known as century eggs or hundred-year eggs, are eggs that have been preserved in a mixture of clay, ash, salt, quicklime, and rice hulls for several weeks to several months. This preservation process results in a creamy yolk with a gelatinous texture and a dark, translucent egg white. The eggs have a strong, savory flavor with hints of ammonia and sulfur.

Preserved duck eggs are commonly used in various dishes in Asian cuisine, such as congee, salads, and pickled vegetables. They are also enjoyed on their own as a flavorful and unique snack.

Signs That Your Preserved Duck Eggs Have Gone Bad

Preserved duck eggs can spoil if they are not stored properly or if they are past their expiration date. Here are some signs that your preserved duck eggs may have gone bad:

Visual Inspection

1. Mold Growth: If you see any mold growth on the eggshell or within the preserved egg, it is a clear indication that the egg has spoiled.
2. Discoloration: If the egg white or yolk has changed color significantly, such as turning green or black, it is a sign of spoilage.
3. Cracked or Leaking Eggs: Cracks or leaks in the eggshell can allow bacteria to enter the egg, leading to spoilage.

Smell

1. Foul Odor: If the preserved duck egg emits a foul or rotten smell, it is a strong indication that the egg has gone bad. Trust your sense of smell when determining the freshness of preserved eggs.

Texture

1. Slimy or Slimy Texture: If the egg white or yolk feels slimy or has a strange texture, it is likely spoiled.

Proper Storage of Preserved Duck Eggs

To ensure the longevity and freshness of your preserved duck eggs, proper storage is essential. Follow these tips to store your preserved duck eggs correctly:

1. Keep in the Refrigerator: Store preserved duck eggs in the refrigerator to maintain their freshness. The cold temperature helps slow down the growth of bacteria.
2. Store in an Airtight Container: Place the preserved duck eggs in an airtight container to prevent them from absorbing odors from other foods in the refrigerator.
3. Avoid Direct Sunlight: Keep the preserved duck eggs away from direct sunlight or heat sources, as exposure to light and heat can cause them to spoil faster.
4. Check Expiration Date: Always check the expiration date on the packaging of the preserved duck eggs and consume them before the date indicated.
5. Rotate Stock: If you have multiple preserved duck eggs, use the oldest ones first to ensure freshness.
