Standard Method Performance Requirements (SMPRs) for Selected Residual Solvents in Color Additives from Crop-Based Sources

AOAC SMPR 2023.004 establishes standardized performance requirements for detecting selected residual solvents in crop-based color additives such as turmeric, beet juice, paprika, and annatto. These matrices contain complex pigments and co-extracted oils that interfere with standard analyses. Laboratories conducting this work should implement gas chromatography (GC) paired with either mass spectrometry (MS) or flame ionization detection (FID). The instruments below are fully compliant and support regulated, high-throughput workflows across diverse botanical matrices.
