General Tips for Bananas

Storage temperatureRelative Humidity (RH)DurationPre-coolingSensitivity to ethyleneEthylene ProductionControlled Atmosphere
Storage temperature: 13° - 14° C
Relative Humidity (RH): 85%-90%
Duration: 2-5 weeks
Pre-cooling: Not required
Sensitivity to ethylene: High
Ethylene Production: Medium
Controlled Atmosphere: Not recommended

Storage Temperature: Recommended range is 13 °C – 14 °C.

Ventilation: Install a digitally controlled ventilation mechanism to ensure optimal air exchange within the chamber.

High Humidity: Use an air-cooler with a low air–product temperature differential (ΔT).

Storage Duration: Recommended period is 2 – 5 weeks.

Air Circulation: Use inverter-type fans with 24-hour digital control to maintain uniform air distribution.

Chamber Tightness: Ensure airtightness of ripening and storage chambers through detailed inspections using modern infrared thermography systems.

IMPORTANT TIPS
  • Ripen bananas in specialized ripening chambers with 4–8-day cycles at 14.5 °C – 18 °C, applying 100–150 ppm ethylene on the first day.
  • During de-greening and ripening, monitor all readings carefully and use precision instruments for accurate control.
  • Store unripe bananas away from ripening chambers to prevent ethylene exposure.
  • Disinfect cold-storage chambers thoroughly before each use.
  • Avoid temperatures below 13 °C, as they cause chilling injury and surface discoloration.
  • Keep storage chambers separate from ripening rooms, maintaining higher internal air pressure to prevent ethylene infiltration.
  • High CO₂ concentrations during storage can cause texture degradation on the peel surface.
