AOAC Method SMPR 2018.012 Instrumentation Guide

Standard Method Performance Requirements (SMPR) for Quantitation of Peanut by ELISA-Based Methods

AOAC SMPR 2018.012 defines the performance criteria for ELISA-based methods used to quantify peanut residues in raw and processed food products. These methods must detect total peanut protein, including in thermally processed or fermented matrices. The method requires a limit of quantitation (LOQ) of ≤ 1 mg/kg, with an analytical range that includes at least 10 mg/kg. It also requires recovery between 50% and 150%, repeatability (RSDr) ≤ 20%, and reproducibility (RSDR) ≤ 30%. Instrumentation must support absorbance-based ELISA workflows with strong linearity and precise thermal control.
