Eggs are one of the most common foods on the dining table, loved worldwide for their rich protein content and nutritional value. However, under normal room temperature conditions, eggs can only last about 30 days before losing freshness. Over time, they are easily affected by bacteria, which may cause problems such as sticky shells, watery yolks, or spoilage. Rotten eggs not only lose their nutritional value but may also cause food poisoning and serious health risks.
The good news is that using egg cold storage (egg preservation cold room) can effectively extend the storage period of eggs for up to 12 months without spoilage. Cold rooms are currently one of the most reliable solutions for long-term egg preservation.

Egg Cold Storage Methods
1. Sorting and Pre-Cooling
Before storing, eggs must go through strict selection. Damaged, cracked, deformed, or rain-soaked eggs should be removed. Pre-cooling is also essential—it reduces the surface temperature of eggs, allowing them to enter cold storage in better condition. This process minimizes moisture condensation on the shell, which helps reduce bacterial and microbial growth.
2. Temperature and Humidity Control
Maintaining proper storage conditions is the key to successful long-term preservation.
- Optimal temperature: -2℃ to -1℃
- Relative humidity: 85%–90%
During cold storage operation, both temperature and humidity must remain stable. Frequent fluctuations will damage egg quality:
- If humidity is too high, mold may develop.
- If humidity is too low, eggs lose internal moisture quickly, leading to weight loss and reduced freshness.
Therefore, regular monitoring of the cold room’s temperature and humidity is essential for maintaining egg quality.
3. Precautions Before Removing from Storage
When eggs are removed from cold storage, the temperature should be gradually increased. Sudden exposure to warmer air can cause condensation on the shell surface, damaging the protective membrane. Once this membrane is compromised, eggs are highly vulnerable to microbial contamination and spoilage.
Storage Results
With proper egg preservation cold room management, eggs can remain fresh for up to 12 months, ensuring excellent quality, safety, and nutritional value. This makes cold storage an indispensable solution for poultry farms, distributors, and food companies engaged in large-scale egg production and trade.
