National Food Safety Standard - Food Additives -
Oil of eucalyptus (Oil of blue eucalyptus)
1 Scope
This standard applies to the oil of eucalyptus (oil of blue eucalyptus) of which
the essential oil, by steam distillation, is extracted from the fresh leaves and
branches of eucalyptus (Eucalyptus globulus Labill.) or eucalyptus-genus
plants (Eucalyptus spp.), and then prepared by distillation process; the content
of cineole is not less than 80%.
2 Technical requirements
2.1 Sensory requirements
The sensory requirements shall meet the requirements in Table 1.
Appendix A
Determination of safrole content
A.1 Instruments and apparatuses
A.1.1 Chromatograph: According to the provisions in Chapter 5 of GB/T 11539-
2008.
A.1.2 Column: packed column.
A.1.3 Detector: hydrogen flame ionization detector.
A.2 Reagents and standard solutions
A.2.1 Reagents
A.2.1.1 Benzene: Analytically pure, the chromatographical determination purity
is at least 99% under test conditions.
A.2.1.2 Safrole: Under test conditions, the chromatographical determination
purity is at least 99%.
A.2.2 Preparation of standard solution with safrole content of 0.002%
Accurately weigh 1.000g ± 0.0002g of safrole in a 500mL volumetric flask; dilute
to the mark with benzene, and shake well. Accurately absorb 1.0mL of this
solution in a 100mL volumetric flask; dilute to the mark with benzene; shake
well for use.
A.3 Determination method
Area normalization method: Determine the content of safrole according to 10.4
in GB/T 11539-2008. Determine the standard solution (A.2.2) and the sample,
respectively; the injection volume shall be the same. Compare the peak-area of
safrole in the two chromatograms.
A.4 Repeatability and result expression
Carry out according to the provisions of 11.4 in GB/T 11539-2008.
The gas chromatogram of safrole in food additive oil of eucalyptus (oil of blue
eucalyptus) and safrole standard solution is shown in Appendix B.
