Temperature and humidity control are key to stable storage. Below are commonly cited ranges and practical tips for everyday use.
Temperature
- Common range: Often suggested at 20°C–25°C; some sources consider 20°C–30°C acceptable, but prolonged exposure above 30°C or below 0°C is generally avoided.
- Impact: Higher temperatures may accelerate aroma loss and increase pest risk; very low temperatures can affect texture stability.
Humidity
- Common range: Relative humidity is often kept around 40%–65%; some practices allow 60%–70%, but avoiding levels above 80% is advised.

- Impact: Excess humidity can lead to dampness and mold, while overly dry conditions can make the peel brittle and reduce aroma.
Storage Tips
- Containers: Use sealed bags or jars (ceramic, glass, or metal). Ceramic jars are slightly breathable and require humidity control; metal jars seal well but should be kept away from heat.

- Placement: Store away from walls, floors, and ceilings (about 10–20 cm clearance). Choose a cool, dry, ventilated spot and avoid direct sunlight.
- Routine checks: Observe color, aroma, and texture regularly. If airing is needed, choose a clear, dry day and spread the peel evenly.
Overall, 20°C–30°C and 40%–65% relative humidity are common reference ranges, with adjustments based on local climate.
