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.
