AOAC Method SMPR 2017.007 Instrumentation Guide

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

AOAC SMPR 2017.007 outlines the essential method performance requirements for identifying and quantifying all-trans lutein and its cis isomers in nutritional formulas. This method applies to all formats, including ready-to-feed liquids, reconstituted powders, and liquid concentrates. Validated methods must achieve a limit of quantitation (LOQ) of ≤1 μg/100 g and provide accurate measurements across an analytical range of 1–800 μg/100 g. Laboratories must also meet recovery rates of 90–110% and maintain repeatability (RSDr) of ≤8% and reproducibility (RSDR) of ≤15% for low concentrations. For higher ranges, RSDr must not exceed 5%, and RSDR should remain within 10%.

Any analytical technique is considered acceptable if it meets these performance criteria, with a strong emphasis on resolving lutein from zeaxanthin. Detection methods must also demonstrate strong accuracy, especially when separating cis and trans isomers of lutein. Proper validation, including blank and midrange check standards, ensures compliance with AOAC expectations. Suitable reference materials, such as NIST SRM 1869, are recommended to ensure reliable calibration. The instrumentation options listed below have demonstrated capability to support this method’s requirements when paired with validated SOPs and internal quality control procedures.
