- Introduction
Standard Framework and Technology Evolution
As the first special specification for fennel in the supply and marketing cooperative industry, this standard inherits the GB/T 12729 series of spice standard systems, and adds the quantitative index of homologous heterogeneity (≤3g/100g) and the volatile oil dry basis determination requirement (≥1.5mL/100g). Compared with the general standard GB/T 15691, it directly quotes the latest limit requirements of GB 2762 in terms of pollutant control.

Key detection technology points
Case study of volatile oil determination
A company sent a fennel powder sample for testing. The steam distillation method was used in accordance with GB/T 30385 for determination. The distillation time was controlled to be 2 hours. The receiver scale was accurate to 0.05mL. The volatile oil content was 1.8mL/100g (dry basis), which met the standard requirements.
Identification of homologous heterologous substances
Through observation under a stereomicroscope, it was found that there were 3 stem fragments (length>2mm) in the sample, which accounted for 2.7g/100g after weighing, and was judged as unqualified. Corrective measures include strengthening raw material screening and magnetic separation equipment calibration.
Implementation suggestions
- Raw material control: The harvest period should be selected when the seed fullness is ≥90%, and avoid mixing in non-seed parts such as pedicels
- Processing technology: The crushing process needs to control the temperature to <40℃ to prevent the loss of volatile oil
- Packaging improvement: It is recommended to use aluminum foil composite bags + deoxidizers to extend the shelf life to 18 months
