AOAC Method SMPR 2020.010 Instrumentation Guide

Standard Method Performance Requirements (SMPR) for Targeted Testing of Vegetable Oils and Low-Quality Olive Oils in Extra Virgin Olive Oil (EVOO)

AOAC SMPR 2020.010 defines the performance requirements for methods used to detect adulteration of extra virgin olive oil (EVOO) with other vegetable oils and low-quality olive oils. The method must identify and quantify adulterants at levels as low as 10% by weight. Precision thresholds include ≤10% repeatability (RSDr) and ≤18% reproducibility (RSDR), with recovery falling between 80–120% and accuracy within ±20%. The method must also avoid false positives from pure EVOO and provide specific identification of each adulterant rather than generic adulteration.
