Spray Drying Herbal & Botanical Extracts
How a spray dryer turns herbal and botanical (TCM) extracts into instant granules and powders, raising purity while keeping active compounds intact.
Herbal and traditional-medicine extracts — water or alcohol extractions of botanicals — are spray-dried into instant granules and powders that are easy to formulate into capsules, tablets and soluble granules.
The drying challenge
- Heat-sensitive actives — flavonoids, saponins and similar compounds degrade with prolonged heat.
- Concentration and purity must improve, not the reverse.
- A sticky, sugar-rich extract that can be hard to dry to a free-flowing powder.
Why spray drying fits
- Higher purity. Spray drying an extract can raise purity by 15–20% versus the starting liquid.
- Low active loss. The seconds-long drying keeps the loss of active compounds under 5%.
- Instant, formulation-ready powder that dissolves quickly and presses or fills easily.
- Carrier options such as maltodextrin help dry high-sugar extracts and improve flow.
Figures are industry-typical for spray drying; verify against your own material before relying on them as guarantees.
