Century eggs, often regarded as an acquired taste, are a delicacy in various Asian cuisines. These preserved eggs, known for their distinctive appearance and unique flavor, are enjoyed by many but can raise questions about storage and consumption practices. One of the most common queries surrounding century eggs is whether they need to be refrigerated. In this comprehensive article, we will explore century eggs, their storage requirements, how they are made, health considerations, and tips for enjoying them.
What Are Century Eggs?
Century eggs, also called “hundred-year eggs” or “millennium eggs,” are a traditional Chinese delicacy made from duck, chicken, or quail eggs. The eggs undergo a preservation process that involves a chemical reaction with alkaline solutions, creating their characteristic dark hue and unique flavor profile.
The process of making century eggs usually involves the following steps:
- **Preparation**: Fresh eggs are cleaned and prepared for preservation.
- **Alkaline Mixture**: The eggs are coated with a mixture of clay, ash, quicklime, and salt, which contributes to the aging process.
- **Aging**: The coated eggs are stored for several weeks to several months, allowing the transformation of the egg’s flavor and texture.
The result is an egg with a dark green yolk, a jelly-like texture, and a strong flavor that some describe as earthy or pungent. In addition to their unique appearance and taste, century eggs are revered for their culinary versatility and are commonly served in salads, congee, or as appetizers.
How to Store Century Eggs: Refrigeration Explained
When it comes to storing century eggs, the question of refrigeration often arises. Do century eggs need to be refrigerated? The answer is not straightforward, as it depends on several factors, including the condition of the eggs, the length of storage, and intended consumption.
Room Temperature Storage
In general, unopened century eggs can be stored at room temperature for a short period, particularly if they are kept in a cool, dry place. The preservatives used during the aging process can keep the eggs safe from spoilage for weeks or even months.
However, it is crucial to consider the following factors:
- Timeframe: Ideally, century eggs should be consumed within a few weeks of purchase if stored at room temperature.
- Environmental Conditions: Humidity and temperature can affect their longevity. High humidity can lead to spoilage, while cooler temperatures can extend their shelf life.
Refrigeration Recommendations
To maximize freshness and ensure safety, refrigeration is recommended once you have broken the seal on the packaging or if you intend to store the eggs for more than a few weeks.
- Opened Century Eggs: Once the packaging is opened, it is essential to refrigerate leftover century eggs. Store them in an airtight container and consume them within a week for the best texture and flavor.
- Unopened Century Eggs: While unopened century eggs can remain at room temperature for a longer duration, refrigeration can help preserve their flavor, especially if you’re in a warmer climate.
Understanding the Shelf Life of Century Eggs
The shelf life of century eggs can be influenced by various factors, such as storage conditions and the method of preservation used. Here’s a general overview of the expected shelf life based on different storage methods:
| Storage Method | Shelf Life | Notes |
|---|---|---|
| Room Temperature (Unopened) | Up to 1 month | Store in a cool, dry place |
| Refrigerated (Unopened) | Up to 6 months | Maintain consistent cold temperature |
| Opened (Refrigerated) | 1 week | Store in an airtight container |
These estimates may vary based on the manufacturer and specific storage techniques, so always check for any signs of spoilage before consumption.

Do century eggs need refrigeration?
Century eggs do not necessarily require refrigeration if they are properly stored. In a cool, dry place, unpeeled century eggs can remain edible for several months. The preserving process creates an environment that inhibits bacterial growth, allowing these eggs to maintain their quality for longer periods without the need for refrigeration.
However, if you live in a particularly warm or humid environment, it’s recommended to refrigerate century eggs, especially once they are peeled or cut. Using proper storage methods, such as sealing them in an airtight container, can help prolong their freshness and prevent them from absorbing odors from other foods in the refrigerator.
How long do century eggs last?
Unpeeled century eggs can last for several months when stored in a cool and dry environment. Some sources suggest that they can remain good for six months or even longer if kept in optimal conditions. However, the quality may diminish over time, affecting flavor and texture. Therefore, it’s best to consume them within a reasonable time frame to fully enjoy their unique characteristics.
Once century eggs are peeled or cooked, their shelf life decreases significantly. Typically, peeled century eggs should be consumed within a week if stored in the refrigerator. If they show any signs of spoilage, such as off smells or discoloration, it’s best to discard them for safety reasons.
Can I eat century eggs raw?
Yes, century eggs can be consumed raw, and they are often enjoyed this way in various dishes. The preservation process effectively transforms the eggs, making them safe to eat without further cooking. They are commonly sliced and served with soy sauce, vinegar, or added to salads and congee. Many people appreciate their unique flavor and texture when eaten raw.
However, individuals with compromised immune systems or certain health conditions should exercise caution when consuming raw items, including century eggs. Additionally, it’s advisable to ensure that the century eggs are sourced from a reputable supplier to guarantee their safety and quality before consuming them raw.

The preservation process enhances the nutrient profile of the eggs, potentially making certain nutrients more bioavailable. In moderation, century eggs can provide a flavorful addition to your diet while delivering these nutritional benefits.
However, it’s important to enjoy century eggs in moderation, as they can be high in sodium due to the preserving process. Excessive consumption may lead to increased sodium intake, which can have health implications for those with high blood pressure or cardiovascular concerns. Balancing your intake with fresh foods can help incorporate century eggs into a healthy diet.
How do I store century eggs?
To store century eggs properly, it’s best to leave them unpeeled and place them in a cool, dry location away from direct sunlight. This helps maintain their quality for as long as possible. If you need to refrigerate them, ensure they are stored in an airtight container to prevent them from absorbing any odors or moisture from the fridge, which could affect their flavor.
Once you peel century eggs, they should be consumed within a week. Store peeled eggs in a covered container in the refrigerator to retain their freshness. Always check for any signs of spoilage, and when in doubt, it’s safer to discard them rather than risk foodborne illness.
