AOAC Method SMPR 2015.004 Instrumentation Guide

Standard Method Performance Requirements (SMPR) for Total Vitamin B3 (Niacin) in Infant and Adult/Pediatric Nutritional Formula

AOAC SMPR 2015.004 sets the performance criteria for determining total vitamin B3—defined as the sum of nicotinic acid and nicotinamide—in nutritional formulas. These requirements apply to powdered, liquid concentrate, and ready-to-feed forms of infant, adult, and pediatric products. Methods must support a quantitation range of 200 to 10,000 µg/100 g, with a limit of quantitation (LOQ) of no more than 200 µg/100 g. The required recovery range is 90–110%, and precision must be demonstrated with RSDr ≤ 5% and RSDR ≤ 10%. Validation must be performed using certified reference material such as NIST SRM 1849a.

Chromatographic methods used for compliance must deliver stable baselines, clear peak separation, and low detection limits. Detection is typically performed with HPLC equipped with UV, diode array (DAD), or fluorescence (FLR) detectors. Systems must handle complex food matrices while maintaining consistency across sample batches. Internal validation of methods and use of system suitability tests at low and midrange levels are critical for accuracy. The instruments listed below are fully compatible with these performance requirements when used with validated sample prep and chromatographic protocols.
