3 Term and definition
For the purposes of this International Standard, the following term and definition apply.
3.1
oil of nutmeg, Indonesian type
essential oil obtained by steam distillation of the dried and crushed nuts of Myristica fragrans Houtt, of the Myristicaceae family, cultivated primarily in the Indonesian archipelago
4 Requirements
4.1 Appearance
Clear mobile liquid.
4.2 Colour
Almost colourless to light yellow.
4.3 Odour
Spicy, sweet, aromatic, with charactenstic nuances.
4.4 Relative density at 20 °C, d Minimum: 0,885 0
Maximum: 0,9070
4.5 Refractive index at 20 °C
Minimum: 1,475 0
Maximum: 1,4850
4.6 Optical rotation at 20 °C Between + 60 and + 180.
4.7 Miscibility in ethanol (volume fraction
90%) at 20 °C
1 volume of the oil shall not require more than 5
volumes of ethanol (volume fraction 90 %) to obtain a
solution, sometimes with opalescence. However, 3 or 4
volumes are adequate in the case of freshly distilled
oils.
4.8 Residue on evaporation Maximum: 2%
4.9 Chromatographlc profile
Analysis of the essential oil shall be carried out by gas chromatography. In the chromatogram obtained, the representative and characteristic components shown in Table 1 shall be identified. The proportions of these components, indicated by the integrator, shall be as shown in Table 1. This constitutes the chromatographic profile of the essential oil.
4.10 Flashpolnt
Information on the flashpoint is given in annex B.
5 Sampling
See ISO 212.
Minimum volume of test sample: 25 ml.
NOTE This volume allows each of the tests specified in ISO 3215 to be carried out at least once.
