General Tips for Pumpkins
| Storage temperature | Relative Humidity (RH) | Duration | Pre-cooling | Sensitivity to ethylene | Ethylene Production | Controlled Atmosphere |
|---|---|---|---|---|---|---|
|
Storage temperature:
12,5° - 15° C
|
Relative Humidity (RH):
65%-75%
|
Duration:
4-7 months
|
Pre-cooling:
Not required
|
Sensitivity to ethylene:
Medium
|
Ethylene Production:
Low
|
Controlled Atmosphere:
Not recommended
|
Air Recirculation: Requires dedicated, digitally controlled systems to ensure continuous and uniform air distribution throughout the chamber, 24 hours a day. |
Pallet Placement: Maintain 5–10 cm spacing between pallets along the airflow direction to allow consistent cooling and prevent heat pockets. |
IMPORTANT TIPS
- Avoid storage below 10°C: low temperatures cause chilling injuries.
- Avoid storage above 15°C: leads to weight loss, color fading, and flavor deterioration.
- Do not compress or stack pumpkins tightly during storage.
- Ensure continuous air recirculation within the cold room for even temperature distribution.
- Remove ethylene through proper ventilation and avoid storing pumpkins with ethylene-producing products.
- Disinfect all handling and storage equipment — including harvesting crates, containers, and cold rooms — before use.
- Use well-ventilated packaging that allows air to circulate through the fruit for more effective cooling, leaving gaps between pallets to facilitate airflow.
