Which production standards does zhike fruit peel oil comply with?
There is no dedicated GB or ISO product standard for zhike (immature bitter-orange peel) oil; compliance is built from three layers. First, the raw material follows the Chinese Pharmacopoeia 2020 monograph for Aurantii Fructus (Citrus aurantium L. and cultivated varieties, dried immature fruit). Second, processing and testing follow the Chinese essential-oil method standards: GB/T 11538-2006 (capillary GC analysis), GB/T 11540-2008 (relative density) and the GB/T 14454 series (refractive index, optical rotation, acid/ester values as applicable). Third, the product specification is an enterprise standard drafted on the bitter-orange peel / daidai family reference windows, with batch COA as the acceptance document.
Sibling reference: the 2025 group standard T/JGE 3036-2025 covers zhike flower essential oil by SFE-CO₂ + molecular distillation — a related article of the same orchards, useful as co-production context (see GD22 standards file for the full list).
