General Tips for Lychees

Storage temperatureRelative Humidity (RH)DurationPre-coolingSensitivity to ethyleneEthylene ProductionControlled Atmosphere
Storage temperature: 4° - 7° C
Relative Humidity (RH): 90%-95%
Duration: 2-4 weeks
Pre-cooling: Air cooling
Sensitivity to ethylene: Low
Ethylene Production: Low
Controlled Atmosphere: Not recommended

Storage Temperature: Recommended range is 4 °C – 7 °C.

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

Storage Duration: Recommended period is 2 – 4 weeks.

Controlled Atmosphere: Not recommended — uneconomical for small production volumes and provides minimal advantage compared to conventional storage.

Ozone: It is advised to install a unit capable of delivering the required ozone concentration to reduce microbial load and preserve fruit surface quality.

IMPORTANT TIPS
  • Rapid cooling and maintaining the cold chain throughout all handling and distribution phases are essential.
  • Maintaining elevated CO₂ levels supports product quality but should not exceed ~15 %, as higher concentrations can cause off-odours.
  • Handle lychees with care — they are harvested fully ripe and are non-climacteric fruits, meaning they do not continue ripening after harvest.
