Store at 0 °C to 1 °C for optimal preservation.

Use a cooler setup that maintains a minimal air–product temperature differential (ΔT) for high humidity storage.

Typical storage period under proper conditions: 4 to 8 weeks.

Install a digitally-controlled ventilation system to manage buildup of ethylene (C₂H₄) and carbon dioxide (CO₂).

Controlled Atmosphere (e.g., 1–2% O₂, 3–4% CO₂) is recommended for longer storage duration and maintaining fruit firmness.

IMPORTANT TIPS
  • Rapid pre-cooling is essential to prevent moisture loss and texture degradation.
  • Maintain a continuous cold chain throughout all handling and storage phases.
  • Apply low-velocity air movement in storage to avoid surface damage.
  • Monitor fruit firmness at harvest (> 4 kg force) and sugar content (< 12 °Brix) for suitability.
  • Disinfect cold-storage facilities before use to prevent microbial contamination.
