How do you ensure batch-to-batch consistency?
Batch-to-batch consistency is enforced by GC-MS fingerprint release, HPLC standardization of sanshool amides, fixed raw-material sourcing, and ±10–15% compositional tolerance.
Consistency System
| Control | Detail |
|---|---|
| GC-MS fingerprint | Every batch matched to the reference chromatogram (T/CFNA 6101-2020 regional profile) |
| HPLC standardization | Sanshool amide content controlled within specification; standardized grades held to target ±5% |
| Raw-material policy | Fixed Dao-di origins and blending of multiple orchard lots to average seasonal variation |
| Process control | Fixed extraction parameters per grade; in-line monitoring of density, RI, and yield |
| Release tolerance | Key monoterpenes (limonene, linalool, myrcene) within ±10–15% of reference |
| Stability reserve | Retained samples per batch held 36 months for arbitration |
- Year-on-year variation is reduced by blending across sub-regions within the same Dao-di province
- Any drift beyond tolerance blocks release until re-blending
- COA trend reports are available for your quality team
