AOAC Method SMPR 2017.019 Instrumentation Guide

Standard Method Performance Requirements (SMPR) for Quantitation of Cannabinoids in Edible Chocolate

AOAC SMPR 2017.019 establishes performance-based criteria for the quantification of cannabinoids in edible chocolate products. This includes major analytes such as tetrahydrocannabinol (THC), cannabidiol (CBD), and other cannabinoids across dark, milk, and white chocolate matrices. The standard specifies a limit of quantitation (LOQ) of ≤ 0.008% by weight and an analytical range of 0.008% to 5% w/w. Methods must also demonstrate recovery between 90–110% for low concentrations and 95–105% for higher concentrations, with repeatability (%RSDr) ≤ 5% and reproducibility (%RSDR) ≤ 8%. Laboratories may use HPLC with diode array detection or LC-MS/MS systems to meet these criteria, provided performance is confirmed through validation.
