How do you ensure batch-to-batch consistency of this sweet orange oil?

Batch consistency is managed through blending to spec, standardized harvest sourcing and release testing — so successive shipments match your approved sample within defined quality tolerances.

Consistency Management

MeasureDetail
Spec blendingNew production is blended against the reference spec (limonene, aldehydes, physical constants)
GC-MS fingerprintEvery batch's volatile profile compared with reference standard
Physical checksDensity, refractive index, optical rotation on every lot
Sensory panelOrganoleptic check by trained evaluators before release
Origin disciplineSourcing from the same regions/varieties for each program
Retained samplesKept for each batch for post-shipment comparison
  • Citrus oils vary naturally with season and orchard; our blending step irons out natural variation to hold the agreed spec
  • Tolerances follow the standard ranges in ISO 3140:2019 / GB/T 11424-2008 — batch-to-batch differences are kept well inside these limits
  • A retained sample of every batch is kept for at least 24 months for reference
  • If your process needs tighter tolerances, we agree a custom spec with you and blend to it
  • For annual programs, we can hold one 'anchor batch' profile and match all subsequent lots to it
