How consistent are batches of this lemongrass oil?
Batch consistency is managed by locking the raw material and the process: same farms and same harvest windows, identical steam-distillation parameters, and GC-MS fingerprint comparison against a retained reference sample for every batch. The three acceptance criteria — citral content, myrcene limit and optical rotation — are checked on every lot.
Consistency Controls
| Control | Method | Purpose |
|---|---|---|
| Raw material lock | Fixed farms, fixed harvest windows (3-4 cuts/year) | Stable citral level |
| Process lock | Same distillation columns and parameters | Repeatable composition |
| GC-MS fingerprint | Compare against retained reference sample | Visual proof of similarity |
| Citral assay | NaHSO3 adduct + GC-FID (ISO 11024-1) | Main marker locked |
| Myrcene limit | <20% by GC | Early-harvest / adulteration screening |
| Optical rotation | -3° to +1° | Authenticity veto |
| Retained samples | 24 months for every batch | Traceability and re-testing |
- Typical industrial batches run around 60% citral; the natural batch-to-batch spread is small when the same farms and window are used
- For customers needing a constant year-round profile, we can blend pooled batches against the reference sample
- If your internal acceptance window is tighter than our standard, tell us the limits and we will lock the production plan to hit them
