General Tips for Groundcherry (Physalis)
| Storage temperature | Relative Humidity (RH) | Duration | Pre-cooling | Sensitivity to ethylene | Ethylene Production | Controlled Atmosphere |
|---|---|---|---|---|---|---|
|
Storage temperature:
12° – 14° C
|
Relative Humidity (RH):
80%-85%
|
Duration:
3-4 weeks
|
Pre-cooling:
Not required
|
Sensitivity to ethylene:
Medium
|
Ethylene Production:
Low
|
Controlled Atmosphere:
Not recommended
|
Ventilation: Installation of a digitally controlled ventilation system to remove respiration gases and maintain uniform air quality within the storage chamber. |
Modified Atmosphere Packaging (MAP): The use of special MAP bags is recommended, as it extends storage life and helps preserve fruit color, texture, and quality. |
Pallet Arrangement: Maintain 5–10 cm spacing between pallets to promote proper air circulation and achieve consistent temperature throughout the chamber. |
IMPORTANT TIPS
- Do not store physalis with ethylene-producing fruits (e.g., apples, pears, peaches, nectarines), as this can cause unwanted color changes and stem detachment.
- Remove ethylene through ventilation or absorbers.
- Use Modified Atmosphere Packaging (MAP) to extend shelf life and maintain quality.
- Ensure gentle air circulation — low airflow speeds help avoid dehydration or bruising.
- Avoid temperatures below the recommended range, as chilling injury may occur.
- Store in well-ventilated containers that allow air to pass freely through the product.
- Maintain adequate spacing between pallets and chamber walls for proper cold air movement.
