General Tips for Melons
| Storage temperature | Relative Humidity (RH) | Duration | Pre-cooling | Sensitivity to ethylene | Ethylene Production | Controlled Atmosphere |
|---|---|---|---|---|---|---|
|
Storage temperature:
8° - 10° C
|
Relative Humidity (RH):
75%-80%
|
Duration:
2-6 weeks
|
Pre-cooling:
Air cooling
|
Sensitivity to ethylene:
High
|
Ethylene Production:
Medium
|
Controlled Atmosphere:
Not recommended
|
Storage Temperature: Recommended range is 8 °C – 10 °C. |
Storage Duration: Recommended period is 2 – 6 weeks. |
Ventilation: Install a digitally controlled ventilation system to regulate chamber air exchange. |
Controlled Atmosphere: Not recommended — uneconomical for small production volumes, with limited advantages in total storage life. |
Ethylene Removal: Use a specialized ventilation or ethylene-extraction system. |
IMPORTANT TIPS
- Harvest melons unripe — they can continue to ripen during storage.
- Monitor sugar content at harvest using optical refractometers; optimal levels are below 10 °Brix.
- Avoid temperatures below 7 °C, as they cause flavor and skin deterioration.
- Use a low-humidity refrigeration system to prevent surface damage.
- Perform rapid pre-cooling before commercial dispatch.
- Remove ethylene continuously to avoid premature ripening.
- Maintain elevated CO₂ levels, which slow ripening and extend storage life — however, concentrations above 20 % can cause off-flavors and product degradation.
