AOAC Method SMPR 2017.006 Instrumentation Guide

Standard Method Performance Requirements (SMPR) for Determination of β-Carotene in Infant and Adult/Pediatric Nutritional Formula

AOAC SMPR 2017.006 outlines strict criteria for measuring all-trans β-carotene and its cis isomers in various nutritional formulas. It applies to powders, ready-to-feed liquids, and liquid concentrates intended for infants, adults, and pediatric patients. Methods must meet a quantitation limit of ≤1 μg/100 g and cover an analytical range from 1 to 1300 μg/100 g of reconstituted product. Additionally, recovery must fall between 90–110%, with RSDr ≤8% and RSDR ≤15% for concentrations up to 100 μg/100 g, and RSDr ≤5% and RSDR ≤10% for higher concentrations. Instruments must resolve β-carotene from structurally similar compounds like lycopene and α-carotene.

This SMPR allows any analytical technique that meets its performance criteria. However, HPLC and UPLC systems with photodiode array or diode array detectors are commonly used due to their ability to resolve isomeric carotenoids. To meet the method’s requirements, laboratories should employ systems with validated wavelength stability, gradient precision, and software capable of consistent quantitation and retention time reproducibility. Below are leading analytical platforms that can support compliant β-carotene analysis in formula matrices when appropriately validated.
