The method used for Onuku’s mānuka oil extraction is steam distillation. Steam distillation is used as it is a separation process used to purify or isolate temperature-sensitive materials. This extraction method is widely used for essential oils.
Onuku always get our mānuka oil tested – the GCFID test and the test result is on the NFC tag on every bottle. For an oil to be called Mānuka it must have a ß-triketone reading. β-Triketones are found mainly (we cannot say only) in trees and shrubs of the Myrtaceae, particularly the genera Eucalyptus and Leptospermum scoparium. With the GCFID test results this is our guarantee that our mānuka oil is authentic. Flavesone, leptospermone, isoleptospermone and grandiflorone are naturally occurring organic compounds collectively known as β-Triketones. If none of these are detected in the GCFID test results then the sample is not mānuka oil.
