Yes, turmeric can be dried in the sun, and it is actually the most common method used for drying turmeric rhizomes.
Sun drying is a traditional and cost-effective method for preserving turmeric. Here's a breakdown of the process:
-
Preparation: The turmeric rhizomes are first cleaned and then boiled or steamed. This process, called curing, helps to develop the characteristic color and flavor of turmeric.
-
Slicing (Optional): While not always necessary, slicing the rhizomes into smaller pieces can significantly reduce drying time.
-
Sun Drying: The prepared rhizomes are then spread out in a single layer on a clean surface (like mats or concrete floors) in direct sunlight.
-
Turning: They need to be turned regularly (at least once or twice a day) to ensure even drying and prevent mold growth.
-
Duration: The drying process can take anywhere from 5 to 7 days, depending on the intensity of the sunlight and the humidity levels. The turmeric is considered dry when it becomes hard and brittle.
However, while sun drying is widely used, it's important to note that it can lead to some loss of volatile oils, which contribute to turmeric's flavor and aroma. The color may also be less vibrant compared to other drying methods. To mitigate these issues, some producers use a combination of sun drying and mechanical drying.
