General Tips for Avocados
| Storage temperature | Relative Humidity (RH) | Duration | Pre-cooling | Sensitivity to ethylene | Ethylene Production | Controlled Atmosphere |
|---|---|---|---|---|---|---|
|
Storage temperature:
5 έως 8°C
|
Relative Humidity (RH):
90%-95%
|
Duration:
4 – 6 weeks
|
Pre-cooling:
Forced-air cooling
|
Sensitivity to ethylene:
High
|
Ethylene Production:
Very high
|
Controlled Atmosphere:
Not recommended
|
Storage Temperature: Maintain at 5 – 8 °C. |
High Humidity: Install humidifiers capable of reaching the upper RH range, or choose forced-air cooling systems operating with a minimal air–product temperature differential (ΔT). |
Storage Duration: Recommended 4 to 6 weeks. |
Ethylene Removal: Use an ethylene burner or an ethylene absorption unit, as avocados are highly sensitive to trace ethylene. |
Controlled Atmosphere: Not recommended for small-scale production—limited benefit relative to cost. |
Ozone Application: Recommended installation of ozone generator to reduce microbial load. |
Ventilation & Air Exchange: Digital-controlled ventilation mechanism is advised for the chamber. |
Pre-Cooling: Conduct a specialized study of absorption time and air velocity to ensure uniform cooling, reaching the core of the product. |
-
Conduct rapid pre-cooling after harvest and before commercial dispatch.
- Maintain the cold chain at all stages of handling and distribution.
- Remove ethylene exposure — avocados exhibit high sensitivity to trace ethylene.
- For ripe avocados: A treatment of 10 ppm ethylene at 20 °C can ripen fruit in 48 hours.
- Sanitize cold-rooms before use to control microbial load.
- CO₂ management: Keeping CO₂ at low levels supports better retention, but levels above ~10% may deteriorate flavour.
