Evaluating Essential Oil Quality: Testing, Analysis and Adulteration

with Prabodh Satyal, PhD and Aaron Sorensen, MS

So you are taught the importance of obtaining a GC/MS report with your essential oils, then what? What does it tell you? What should you look for? How can it benefit your essential oil selection?


In this 2-day workshop, Dr. Satyal and Aaron Sorensen from the Aromatic Plant Research Center will discuss these questions and more. You'll learn how to interpret a GC/MS report and how adulteration takes place

Learning Objectives:

  • What is Gas Chromatography/Mass Spectrometry and how to read a GC/MS report?
  • How to categorize EO components by classes?
  • What is adulteration and what are the types of adulteration?
  • Trends in EO adulteration and how to overcome?
  • Instruments applied in adulteration detection (Isotope ratio, GCMS, SNIF NMR, Chiral GC/MS, Physical constants, etc)?
  • How to detect carrier oil based adulteration?
  • How to detect synthetic compound based adulteration?
  • What are synthetic markers and biomarkers, what is the importance of them in adulteration detection?
  • Is mislabeling also adulteration?
  • How to detect adulteration if natural isolate has been added which can pass C14 test or chirality test?
  • Is adulteration crime or necessity?
  • What is the impact of adulteration to aroma, farmers, and end users.
  • How to confirm origin of the oils?
  • Why is chemometric based adulteration detection more important than ISO or AFNOR ranges?
  • What is chiral GC/MS and its limitations?

He has studied the chemical composition of more than 10,000 essential oils from various parts of the world, has published more than 100 research articles in peer-reviewed journals, and has been purity analyst (serving in several positions) for nearly ten years. He an editorial member of several journals, including the International Journal of Professional Holistic Aromatherapy (IJPHA). Dr. S has a special interest in essential oil adulteration detection using marker based analysis and has created the only known mass spectral library of synthetic markers. He has played a significant role in establishing several essential oil databases and has spoken at ten reputable international conferences. He is currently developing the first ever fully automated adulteration analysis software for GCMS that will identify the percentage of purity, origin, and mixed sources in essential oils.
