Which extraction method is used — steam distillation, solvent extraction, or CO2?
Standard production uses steam distillation of dried flower heads, delivering a pure, solvent-free oil at a typical yield of about 0.55% on dry flowers; supercritical CO2 extraction (per CN 103710152 B patent parameters) and a two-step Soxhlet-plus-steam process (up to 4.8 mL/kg) are available for premium grades.
Extraction Options
| Method | Yield | Character | Use case |
|---|---|---|---|
| Steam distillation | ~0.55% dry basis | Traditional, solvent-free, cost-efficient | Standard and food-grade (GB 1886.274-2016) |
| Supercritical CO2 | Higher | Closer to fresh-flower aroma, higher purity | Premium perfumery and high-value formulations |
| Two-step (Soxhlet + steam) | up to 4.8 mL/kg | Maximized recovery | Cost-sensitive bulk programs |
