Description
A low‑temperature, ambient‑humidity drying method for herbs.
Technical
The process removes water by passive evaporation, lowering water activity below 0.6 and thereby suppressing microbial metabolism. Simultaneously, the reduction in moisture concentrates phenolic compounds 2–3 ×, boosting antioxidant capacity. UV exposure can accelerate vitamin C loss, so shade drying is often preferred.
