Abstract: Norm ISO 4730-2017
Until recently, the lack of an effective standard made it possible to find falsified TTO essential oils on the market by dilution with other species. This issue has been overcome by the introduction of the new ISO4730 Standard 2017, which introduces new stricter indications for the main 15 terpenes found in the genuine TTO.
The most common TTO fraud is done with eucalyptus and pine oils that are easily detected by GC analysis and chiral enantiomeric analysis that has been incorporated into the new ISO standard (ISO4730: 2017). Falsification with other species of Melaleuca such as cajuput, niaouli, manuka or kanuka oils are rarely present in practice, as they are even too expensive.
For an absolute security of the origin of the TTO, the analysis according to the standard ISO4730 2017 is required.
