AOAC Method SMPR 2020.007 Instrumentation Guide

Standard Method Performance Requirements (SMPRs) for Nontargeted Testing (NTT) of Ingredients for Food Authenticity / Fraud Evaluation of Extra Virgin Olive Oil

AOAC SMPR 2020.007 outlines performance requirements for nontargeted testing methods designed to evaluate the authenticity of extra virgin olive oil (EVOO). Methods must establish a baseline fingerprint using authentic EVOO samples and demonstrate their ability to correctly classify samples adulterated with 5% of sunflower, corn, hazelnut, canola, safflower oils, non-EVOO oils, or falsely labeled origin oils. For each type of adulterant, at least 30 independently sourced samples must be tested, and all must be correctly identified as adulterated. Additionally, the method must produce zero false positives when applied to 30 separate authentic EVOO samples. Validation must cover the full scope of the baseline fingerprint, and the fingerprinting protocol must be fully documented and reproducible.

To meet these criteria, analytical platforms must capture consistent chemical fingerprints that support statistical classification and multivariate modeling. Sample sets used for validation must be independent from those used in creating the baseline model, and must represent the intended application scope. FT-IR, NMR, and high-resolution mass spectrometry platforms are acceptable technologies when configured to meet these validation parameters. The selected instrument must support model reproducibility, traceability, and accuracy across multiple batches. Proper validation ensures that the method achieves the 100% sensitivity and 100% specificity required by AOAC SMPR 2020.007 for EVOO fraud detection. Each system below offers analytical sensitivity and reproducibility appropriate for SMPR 2020.007. Internal validation is necessary to confirm each instrument’s performance against AOAC method requirements.
