General Tips for Aromatic Herbs

Storage temperatureRelative Humidity (RH)DurationPre-coolingSensitivity to ethyleneEthylene ProductionControlled Atmosphere
Storage temperature: 0°–10°C (depending on species)
Relative Humidity (RH): >95%
Duration: 1-4 weeks (depending on species)
Pre-cooling: Air cooling
Sensitivity to ethylene: From minimal to high (depending on species)
Ethylene Production: From very low to medium (depending on species)
Controlled Atmosphere: Not recommended

Low-Pressure Pre-Cooling Chambers (Wet-Bulb Type): Specialized units suitable for unpackaged aromatic herbs immediately after harvest. These systems regulate humidity and create a low-pressure environment that rapidly reduces temperature without damaging delicate tissues.

Dynamic Pre-Cooling (High-Suction Capacity Chambers): Tailored for both packaged and unpackaged herbs. Ensures even temperature distribution by controlling air speed and absorption rate across the entire product mass.

Dynamic Cooling: Multi-point monitoring of temperature and humidity allows precise adjustment throughout the cold room 24/7. Extends storage life by 15–20% beyond standard conditions.

Natural Airflow Cold Room with Mist Atmosphere: A highly specialized chamber combining natural air circulation with fine-mist humidifiers — ideal for products sensitive to air velocity and requiring very high humidity.

IMPORTANT TIPS
  • Manage CO₂ levels: Elevated concentrations help slow deterioration and maintain leaf color.
  • Use high-capacity pre-cooling systems for fast and uniform temperature drop immediately after harvest.
  • Maintain the cold chain during all handling, storage, and transport phases.
  • Install ozone generators to reduce microbial and fungal contamination.
  • Use modified-atmosphere packaging (MAP) to extend shelf life and preserve aroma and texture.
  • Remove ethylene with specialized absorbers to prevent premature yellowing and loss of quality.
