How do you ensure batch-to-batch consistency for bergamot oil?
We ensure batch-to-batch consistency through standardized sourcing, fixed production parameters and GC-MS fingerprint comparison — every batch is released only after it matches the reference profile.
Consistency Controls
| Control | Method |
|---|---|
| Sourcing | Contracted orchards / verified peel lots; origin and cultivar documented per batch |
| Production | Fixed cold-press temperature, centrifuge speed and filtration cycle |
| GC-MS fingerprint | Each batch compared against the master chromatogram (linalyl acetate/linalool/limonene ratio window) |
| Physicochemical | Density, RI, optical rotation, ester value within tight in-house windows |
| Sensory panel | Trained panel evaluates color, clarity and aroma before release |
| Retention samples | Every batch retained 36 months for re-testing and arbitration |
- Natural variations (season, weather) can shift minor components by a few %; we blend from multiple lots when needed to stay inside specification
- If a customer has a reference batch, we can produce a matching blend and verify similarity by GC-MS overlay
- Consistency data across the last 5 batches can be shared for QA review
- For critical programs (large perfume or food accounts), we can set an agreed 'golden standard' batch for continuous matching
