General Tips for Pumpkins

Storage temperatureRelative Humidity (RH)DurationPre-coolingSensitivity to ethyleneEthylene ProductionControlled 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.
