How do you ensure consistency between different batches of osmanthus absolute?
Consistency is managed through controlled harvest windows, standardized extraction parameters, and release testing: every batch must pass the same physical, chemical, and olfactory specification before shipment.
Consistency Controls
| Control | Method |
|---|---|
| Harvest standardization | Flowers picked at the same bloom stage from contracted farms |
| Extraction parameters | Fixed solvent ratio, time, temperature per batch |
| Release testing | Density, RI, acid/ester value within specification |
| Composition control | GC-MS fingerprint compared against reference standard |
| Sensory panel | Trained panel approves aroma before release |
- Natural variation (typically within ±10% for major compounds) is documented in each COA
- For strict brand consistency, we can supply a reference standard and blend-compatible lot matching
- Pre-blend trial lots are available to verify color and odor match before production
If your formulation is sensitive to minor variation, ask about our lot-matching program for continuous production.
