AOAC Method SMPR 2016.004 Instrumentation Guide
Standard Method Performance Requirements (SMPR) for Quantitative Measurement of Beta-Cryptoxanthin, Lutein, and Zeaxanthin in Ingredients and Dietary Supplements
AOAC SMPR 2016.004 defines the method performance requirements for quantifying beta-cryptoxanthin, lutein, and zeaxanthin—including their cis/trans isomers and esters—in dietary ingredients and supplements. This method serves as a reference standard for cGMP compliance and supports regulatory testing across a wide range of matrices such as tablets, capsules, gummies, powders, extracts, and liquids. Methods must achieve an analytical range of 0.0005% to 100% (5 to 1,000,000 ppm) and a limit of quantitation (LOQ) of ≤ 0.0002% (≤ 2 ppm). Acceptable recovery ranges from 80–110% at 5–20 ppm to 98–102% above 1%, with RSDr limits between 2–8% and RSDR limits between 5–12%, depending on concentration. These specifications ensure reliable quantification of carotenoids in compliance with GMP testing standards.
These carotenoids must be quantitated with high specificity and precision, which often requires chromatographic separation of isomers and esters. Compliant instrumentation must support robust analytical workflows validated across diverse supplement formulations. Below is a list of recommended systems—including UPLC, HPLC, LC-MS/MS, and UV-Vis platforms—that fulfill the performance criteria set by AOAC SMPR 2016.004. These instruments are appropriate for laboratories conducting reference method testing in accordance with cGMP quality system regulations.
