Drying in the shade
The raw materials are dried without direct sunlight, maintaining the movement of dry air. Shadow is not synonymous with a hermetically sealed room.
How it works
The water evaporates into the surrounding air. The canopy limits direct light, but air must flow freely around the product; a damp, stationary environment is not suitable for this.
History
Method for sensitive color
FAO describes shade drying for plant materials that lose their attractive color in direct sunlight: herbs, peppers and some other vegetables.
The traditional method requires control
In drying guidelines, ventilation and dry air remain the basis of the process, regardless of the presence of direct light. The word “shady” itself does not describe the sanitary conditions of production.
What changes in the product
Color
The absence of direct sunlight can be beneficial for sensitive coloring. This is a relative advantage for certain raw materials, and not a promise of unchanging color for any berry.
Speed and uniformity
In dry climates with good airflow, the method can work quite quickly; with poor air exchange, moisture escapes worse. For the buyer, this is a reason to clarify the control of batch readiness.
Storage remains important
After achieving the desired dryness, the product still needs to be packaged from moisture. The drying method does not replace the storage conditions on the label.
Pros
- Direct exposure to sunlight is reduced.
- You can use a ventilated shelter without complex heating equipment.
- Useful for some colored and aromatic plant materials.
Limitations
- Strong dependence on humidity and air movement.
- The canopy itself does not protect from dust and pests on all sides.
- It is impossible to determine the method only by the dark or light color of the finished product.
Where is it used?
- Aromatic herbs.
- Peppers and other suitable plant materials under the manufacturer's conditions.
- Fruits - only when the technology of a particular product actually provides for shadow drying.
When to choose
- The appearance and aroma of a particular product are important, and there is information about its processing.
- You choose between samples of the same type based on taste and texture.
When to choose another option
- The seller calls any indoor drying “shade” without explaining the ventilation.
- There is a damp smell or visible signs of spoilage.
What to know before buying
- How did you ensure air movement and protection of raw materials?
- Is there any confirmation that this batch was shade dried?
- Were pre-solutions, sugar or preservatives used?
- How to store after opening?
