High‐throughput screening of argan oil composition and authenticity using benchtop (1)H NMR

We use 60‐MHz benchtop nuclear magnetic resonance (NMR) to acquire (1)H spectra from argan oils of assured origin. We show that the low‐field NMR spectrum of neat oil contains sufficient information to make estimates of compositional parameters and to inform on the presence of minor compounds. A scr...

description We use 60‐MHz benchtop nuclear magnetic resonance (NMR) to acquire (1)H spectra from argan oils of assured origin. We show that the low‐field NMR spectrum of neat oil contains sufficient information to make estimates of compositional parameters and to inform on the presence of minor compounds. A screening method for quality and authenticity is presented based on nearest‐neighbour outlier detection. A variety of oil types are used to challenge the method. In a survey of retail‐purchased oils, several instances of fraud were found.
