AOAC Method SMPR 2024.006 Instrumentation Guide
Standard Method Performance Requirements (SMPRs) for Determination of Milk Fat Globule Membrane Proteins in Infant and Adult/Pediatric Formula
AOAC SMPR 2024.006 sets the standard performance requirements for quantifying milk fat globule membrane (MFGM) proteins in infant, adult, and pediatric nutritional formulas. These proteins include PLIN2, BTN1A1, MUC1, MFGE8, FABP3, XDH, and GLYCAM1. To meet these standards, laboratories must use LC-MS/MS systems capable of ultra-trace quantification, excellent specificity, and stability in complex food matrices. Below, we highlight high-performance triple quadrupole LC-MS/MS platforms that are fully aligned with the SMPR’s technical and analytical requirements.
The ideal system must support detection limits as low as 0.1 mg/100 g for several target proteins, offer precise quantification via MRM mode, and deliver reproducibility across nutritional matrices. Analytical performance parameters such as recovery, repeatability (%RSDr), and reproducibility (%RSDR) are also critical. The following instruments from leading manufacturers—Agilent, Waters, PerkinElmer, SCIEX, Shimadzu, and Thermo Scientific—have been selected for their strong alignment with the method’s sensitivity, specificity, and operational stability requirements.
