How is jasmine sambac absolute extracted, and how does it differ from a steam-distilled essential oil?
It is produced by solvent extraction (the absolute process), not steam distillation — that is precisely why it is called an absolute and carries jasmine's true depth.
Two-Step Solvent Extraction Process
| Stage | Process | Key parameters |
|---|---|---|
| 1. Concrete | Petroleum-ether maceration of fresh blossoms | 4 L solvent per kg flowers, ~96 min, yield 2.5–2.8% |
| 2. Absolute | Cold ethanol wash to remove waxes | 10x ethanol, freeze at -15 to -20°C for 24–48 h, vacuum concentrate <50°C |
An alternative modern route is supercritical CO2 extraction (31–35°C, 10–13 MPa, 4–7 h), which reaches 3.5–4.0% yield — 15–25 times higher than the traditional method — while preserving a clean, natural aroma.
If your market requires the classic traditional profile, we supply the solvent-extracted version; if you need high-yield, low-residue material, ask for the CO2-extracted batch. Specify your application and we will recommend the right grade with a GC-MS comparison within 48 hours.
