How is this white michelia oil extracted, and why is steam distillation preferred?
The oil is produced by water-steam distillation of fresh white michelia flowers, the method recognized by GB 1886.275-2016, QB/T 1801-2010 and ISO 17382:2007.
Extraction Details
| Item | Detail |
|---|---|
| Method | Water-steam distillation |
| Raw material | Fresh flowers, processed promptly after harvest |
| Yield | 0.08–0.12% (traditional steam distillation) |
| Equipment | 304/316L stainless still, Florentine oil–water separator |
| Standard basis | GB 1886.275-2016 / QB/T 1801-2010 / ISO 17382:2007 |
- Steam distillation keeps the oil 100% solvent-free, which matters for food-additive and cosmetic use
- Because the yield is very low (less than 1.2 kg of oil per ton of flowers), the oil is naturally precious
- Patented alternatives (supercritical CO2 at 0.18–0.22% yield, low-temperature cryo-extraction) exist for enhanced aroma fidelity; standard production remains steam distillation
