How do you ensure batch-to-batch consistency and traceability?

Top controls consistency through Q/XXXX and per-batch GC-MS β-ionone floral fingerprint matched to the reference profile: each lot is matched (melting point, refractive index, yield within band, β-ionone ratio present). Traceability runs flower origin → salting → extraction → concrete with a lot-specific ledger and retention sample.

If your application needs tight tolerances, tell Top and we can select lots from the same orchard/harvest or blend to a target floral profile. Every shipment carries a lot number linking to the COA and GC-MS on file.

Top shares the QC ledger with GD01 osmanthus absolute for concrete→absolute continuity.
