AOAC Method SMPR 2014.005 Instrumentation Guide

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

AOAC SMPR 2014.005 defines the method performance criteria for quantifying total biotin in all forms of infant, adult, and pediatric nutritional formulas. These include ready-to-feed liquids, reconstituted powders, and liquid concentrates. The method must achieve a limit of quantitation (LOQ) of ≤ 0.1 µg/100 g and cover an analytical range of 0.1–150 µg/100 g. Recovery must fall within 80–120% for concentrations between 0.1 and 1 µg/100 g, and 90–110% for concentrations above 1 µg/100 g. Repeatability (RSDr) must be ≤ 8% for low concentrations and ≤ 6% for higher ones, while reproducibility (RSDR) must remain ≤ 16% and ≤ 12%, respectively.

The instrumentation used must deliver accurate and reproducible results, particularly at trace levels of biotin. LC-MS/MS systems are preferred due to their specificity and ability to meet the strict LOQ and recovery requirements. HPLC systems with fluorescence detection may also be used when biotin is derivatized. The following systems meet the AOAC SMPR 2014.005 criteria when configured with validated methods, calibration standards, and quality control materials such as NIST SRM 1849a.
