It is recommended to maintain storage temperature between 0 °C and 1 °C.

High humidity: Choose a forced-air cooler with a minimal air–product temperature differential (ΔT).

The recommended storage period is 2 to 4 months.

Controlled Atmosphere: Recommended—it can effectively extend shelf life and preserve fruit quality.

Install an ozone generator to manage microbial load and consider ethylene removal systems.

Ensure uniform air circulation with inverter-driven fans and full 24-hour coverage of chamber air mass.

IMPORTANT TIPS
  • Rapid pre-cooling after harvest is essential to maintain quality.
  • Maintain the cold chain integrity throughout all logistic phases.
  • Monitor oxygen levels carefully in CA storage (e.g., 1.5%–2% O₂ and 3%–4% CO₂) to suppress ethylene and delay ripening.
  • Properly disinfect cold-storage chambers before use.
  • Segment products based on maturity at harvest to optimize storage outcomes.
