General Tips for Asparagus

Storage temperatureRelative Humidity (RH)DurationPre-coolingSensitivity to ethyleneEthylene ProductionControlled Atmosphere
Storage temperature: 0,20° – 0,80° C
Relative Humidity (RH): 94%-98%
Duration: 3-4 weeks
Pre-cooling: Hydrocooling or air cooling
Sensitivity to ethylene: High
Ethylene Production: Very low
Controlled Atmosphere: Not recommended

Dynamic Pre-Cooling (High-Suction Capacity Units): Ensures uniform temperature absorption and airflow throughout the entire product mass, ideal for packed asparagus.

Natural Airflow Cold Room with Humidified Atmosphere: Advanced cold chambers combining gentle natural airflow and misting systems to maintain optimal humidity and temperature stability for highly sensitive products.

Low-Airflow Cold Room with Continuous Water Circulation: Designed for produce requiring very high humidity with fewer than 25 air recirculations per hour. Humidity is maintained by continuously circulating water.

IMPORTANT TIPS
  • Protect from light exposure and pre-cool immediately after harvest using Hydrocoolers to minimize quality degradation of the spears.
  • Pre-cool after sorting and packaging in Dynamic Pre-Cooling Units and maintain the cold chain throughout handling and transport.
  • Do not transport asparagus with ethylene-producing fruits, as ethylene accelerates tissue hardening and loss of tenderness.
  • Avoid storage temperatures above the optimal range, since excessive heat promotes fiber development, spear hardening, and tip opening.
  • Remove ethylene using absorbers or ventilation systems.
  • Install ozone generators to suppress fungal growth.
  • Control CO₂ concentrations to prevent physiological damage.
  • Use Modified Atmosphere Packaging (MAP) to prolong freshness and maintain spear firmness.
