General Tips for Arugula

Storage temperatureRelative Humidity (RH)DurationPre-coolingSensitivity to ethyleneEthylene ProductionControlled Atmosphere
Storage temperature: 0,5° to 1°C
Relative Humidity (RH): 92%-96%
Duration: 10-16 days
Pre-cooling: Vacuum cooling or air cooling
Sensitivity to ethylene: High
Ethylene Production: Very low
Controlled Atmosphere: Not recommended

Dynamic Pre-Cooling (Low Atmospheric Pressure – Wet Bulb Chambers): Specialized units for unpackaged arugula leaves immediately after harvest. These systems regulate relative humidity and create low pressure, ensuring rapid and uniform temperature reduction.

Dynamic Pre-Cooling (High-Suction Capacity Chambers): Engineered for packaged products, ensuring uniform airflow and temperature distribution throughout the product mass.

Cold Room with Natural Airflow and Nebulized Atmosphere: Combines natural air movement with mist humidification to maintain ideal humidity and protect delicate leaves from dehydration.

Low-Airflow Cold Room with Continuous Water Circulation: Designed for products requiring very high humidity, maintaining consistent moisture through continuous water flow and reduced air recirculation (<25 air changes per hour).

IMPORTANT TIPS
  • Perform rapid pre-cooling in Dynamic Pre-Cooling Units and maintain the cold chain throughout storage and transport.
  • Avoid storing arugula with ethylene-producing fruits such as apples, pears, peaches, and nectarines.
  • Control CO₂ levels — concentrations up to 10% effectively slow leaf yellowing.
  • Remove ethylene using absorption or ventilation systems.
  • Use Modified Atmosphere Packaging (MAP) to extend freshness and shelf life.
  • Install ozone generators to inhibit fungal growth and maintain hygiene.
