AOAC Method SMPR 2016.016 Instrumentation Guide

Standard Method Performance Requirements (SMPR) for Identification of Non-Animal-Derived Proteins in Dietary Supplements

AOAC SMPR 2016.016 outlines the minimum performance requirements for the identification of non-animal-derived proteins in dietary supplements. The method applies to proteins sourced from soy, pea, rice, hemp, flax, and similar plant-based ingredients. Laboratories must detect these proteins at concentrations as low as 0.1% with a probability of identification (POI) of at least 90%. False positives must be avoided, even in the presence of common adulterants such as melamine, peptides under 10 kDa, or free amino acids. Methods must also pass validation across different matrices through single- and multi-laboratory studies.

Instruments used for this method must support high sensitivity, specificity, and reproducibility. LC-MS/MS platforms are strongly recommended due to their ability to differentiate closely related protein sources using peptide markers. Systems must also accommodate various supplement forms, including powders, capsules, and blends with excipients. To meet AOAC SMPR 2016.016, the instrumentation must deliver consistent results with strong matrix tolerance and accurate identification of low-level proteins. The platforms listed below meet or exceed these requirements when properly validated.
