Storage temperature: 11° -12° C
Relative Humidity (RH): 90%
Duration: 2-4 weeks
Pre-cooling: Air cooling
Sensitivity to ethylene: High
Ethylene Production: Low
Controlled Atmosphere: Not recommended

Enhanced Cold Storage Chamber: A flexible system that allows the existing refrigeration chamber and its equipment to be used for light pre-cooling, followed by storage.

Optimal Controlled Atmosphere Composition: A CA mixture of 3%–5% oxygen (O₂) and 10% carbon dioxide (CO₂) helps delay yellowing and slow down the onset of decay for several days.

Ozone: Installation of an ozone generator is recommended to reduce microbial load.

Ethylene Removal: Use ethylene absorption systems to prevent premature yellowing and deterioration.

IMPORTANT TIPS
  • Monitor and manage carbon dioxide (CO₂) levels.
  • High CO₂ concentrations support better preservation of cucumbers.
  • Avoid storage temperatures below 10°C, as chilling injury may occur.
  • Store away from ethylene-producing fruits and vegetables.
  • Use ethylene absorbers and modified atmosphere packaging (MAP) to maintain quality.
  • Pre-cool at 12°C for 2–4 hours using air cooling immediately after harvest.
  • Avoid using ice for retail display, as direct contact with moisture damages the surface.
