General Tips for Pistachios
| Storage temperature | Relative Humidity (RH) | Duration | Pre-cooling | Sensitivity to ethylene | Ethylene Production | Controlled Atmosphere |
|---|---|---|---|---|---|---|
|
Storage temperature:
0° - 5° C
|
Relative Humidity (RH):
65%-75%
|
Duration:
8-12 months
|
Pre-cooling:
Not required
|
Sensitivity to ethylene:
None
|
Ethylene Production:
Very low
|
Controlled Atmosphere:
Not recommended
|
Storage Temperature: Recommended storage temperature is 0 °C – 5 °C. |
Dehumidification: The dehumidification system should allow precise control at the lowest desired humidity level. |
Storage Duration: Recommended period is 8 – 12 months. |
Controlled Atmosphere: Not recommended, as pistachios already have an adequately long storage life and the benefits of CA are minimal. |
Ozone: Installation of an ozone-generation system is recommended to reduce microbial load. |
Air Recirculation: Install a digitally controlled air-recirculation system to ensure complete 24-hour coverage throughout the chamber. |
IMPORTANT TIPS
- Use dehumidification systems with precise humidity control capabilities.
- Thoroughly dry in-shell pistachios before storage.
- Maintain continuous and uniform air recirculation throughout the cold chamber.
- Disinfect the cold-storage rooms before use.
- Avoid exposure to foreign odors that can be absorbed by the product.
- Keeping the temperature below 5 °C helps control insect infestations.
