General Tips for Blueberries
| Storage temperature | Relative Humidity (RH) | Duration | Pre-cooling | Sensitivity to ethylene | Ethylene Production | Controlled Atmosphere |
|---|---|---|---|---|---|---|
|
Storage temperature:
0° C
|
Relative Humidity (RH):
90%-95%
|
Duration:
1 – 2 weeks
|
Pre-cooling:
Not required
|
Sensitivity to ethylene:
High
|
Ethylene Production:
Low
|
Controlled Atmosphere:
Not recommended
|
Storage Temperature: Recommended storage temperature is 0 °C. |
High Humidity: Use an air-cooler with a low air–product temperature differential (ΔT). |
Storage Duration: Recommended period is 1 – 2 weeks. |
Controlled Atmosphere: Not recommended — uneconomical for small volumes and provides limited benefit to total storage life. |
Ozone: Installation of an ozone-generation device is advised to reduce microbial load. |
Ethylene Removal: The use of an ethylene burner or absorption system is recommended. |
Ventilation: A digitally controlled chamber ventilation system should be installed to regulate airflow and maintain gas balance. |
IMPORTANT TIPS
- Rapid cooling and consistent maintenance of the cold chain through all handling and distribution phases.
- Maintain high humidity — blueberries are highly sensitive to dehydration and shrivel easily.
- Regular use of ozone devices supports microbial control.
- Continuous removal of ethylene is necessary to prevent premature aging.
- Maintaining elevated CO₂ levels helps extend storage life and preserve product quality.
