摘要

• Chemical profiling of Coffea arabica by polymeric ionic liquid SPME is described. • Partial least squares regression correlated the aroma fingerprint to adulteration. • Compounds that contributed to the PLS model were identified and assigned. • Trace aroma volatiles exhibited a decisive role in the detection of coffee fraud.
