How is batch-to-batch consistency maintained for this white michelia oil?
Consistency is managed by harvesting at a fixed bloom stage, standardizing the distillation protocol, and matching every batch to a retained reference by GC-MS fingerprint and the full QB/T panel.
Consistency Controls
| Control | Practice |
|---|---|
| Raw material | Same bloom stage and plantation source each season |
| Process | Fixed steam-distillation parameters (time, temperature, ratio) |
| Analytical | GC-MS fingerprint matched to the retained reference standard |
| Physical | Density / refractive index / rotation within specification |
| Chemical | Acid, ester, carbonyl values and linalool ≥50% verified |
- Natural oils vary within biological limits; our specification windows are tight but realistic for a floral oil
- Blending multiple harvest runs equalizes minor seasonal differences for contract supply
- Any out-of-spec batch is re-distilled or rejected rather than blended down
Reference samples are retained for comparison for at least 24 months.
