AOAC Method SMPR 2020.006 Instrumentation Guide

Standard Method Performance Requirements (SMPRs) for Nontargeted Testing (NTT) of Ingredients for Food Authenticity/Fraud Evaluation of Honey

AOAC SMPR 2020.006 defines the performance requirements for nontargeted testing (NTT) methods used to detect economically motivated adulteration in honey. The method requires analytical platforms to distinguish authentic honey from samples adulterated with at least 5% added sugars or molasses. Instruments must generate baseline fingerprints of authentic honey and apply classification models capable of identifying adulterated samples with 100% sensitivity and 0% false positives. These methods must also include validation with 30 independent samples for each adulterant type to ensure robustness across the intended scope.

To meet these criteria, systems must support chemometric tools such as PCA or SIMCA and demonstrate strong reproducibility. Fingerprinting technologies like NMR and FT-IR are well suited for this task. The following instruments are recommended based on their proven capabilities for honey authentication and alignment with the SMPR’s detection, classification, and validation requirements. Each system supports fingerprint acquisition and statistical modeling essential to meet AOAC’s standards for nontargeted food authenticity testing.
