Abstract:
The AOAC Expert Review Panel (ERP) approved a method for the quantitation of curcuminoids for consideration for First Action Official MethodSM status. The previously published method summarized a single-laboratory validation of three individual curcuminoinds-curcumin, demethoxycurcumin, and bis-demethoxycurcumin-in raw materials and finished products. Method performance was compared with AOAC Standard Method Performance Requirement 2016.003. With repeatability precision ranging from 0.3 to 5.5% and recoveries from 96.6 to 103.3% in the different product matrixes, the ERP adopted the method and provided recommendations for achieving Final Action status.
