Detailed explanation of key technical requirements

Gas chromatograph detection stipulates the use of a 5% polyphenylmethylsiloxane quartz capillary column (30m×0.25mm×0.25μm), using a programmed temperature rise method: initially 50℃ for 3min, then raised to 130℃ at 2℃/min, and then raised to 250℃ at 20℃/min for 11min. This method can effectively separate linalool from other terpenes.

Typical application case: A daily chemical enterprise found that the linalool content of essential oil was only 48% according to this standard. After tracing the raw materials, it was found that the accumulation of monoterpene alcohols was insufficient due to the early picking of peppercorns. The standard was met after adjusting the harvest period.

Suggestions for standard implementation

Raw material control: Select green peppercorns with a maturity of ≥90%, and test the moisture content before distillation
Process optimization: It is recommended to use low-temperature segmented distillation (100-120℃) to increase the yield of linalool
Packaging and storage: Galvanized iron barrels or aluminum cans must be used to avoid component adsorption caused by plastic containers

Technology evolution background

Compared with the traditional pepper oil standard, this standard adds a miscibility test (1:1 dissolved in 80% ethanol) to ensure the compatibility of daily chemical product formulas. The 2021 edition includes gas chromatograms in Appendix A for the first time, providing a visual basis for authenticity identification.
