Manufacturing Quality Control of Annatto
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Bixin Content) | UV-Vis Spectrophotometry | Measures absorbance at 480 nm in alkaline solution; quantifies bixin based on molar absorptivity. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration with iodine-based reagent. |
| Ash Content | Gravimetric Analysis | Measures residue mass after incineration at 550 C; indicates inorganic impurities. |
| Heavy Metals (Pb, Cd, As, Hg) | ICP-MS | Quantifies trace metals by ionization in plasma and mass spectrometric detection. |
| Arsenic | Atomic Absorption Spectroscopy (AAS) with Hydride Generation | Converts arsenic to arsine gas, then measures atomic absorption at 193.7 nm. |
| Lead | Graphite Furnace AAS | Atomizes sample in graphite furnace and measures absorption at 283.3 nm for high sensitivity. |
| Solvent Residues (e.g., acetone, ethanol) | Gas Chromatography (GC-FID) | Separates and quantifies residual solvents using flame ionization detection. |
| pH of Aqueous Extract | Potentiometric Measurement | Measures hydrogen ion activity using calibrated pH electrode in standardized suspension. |
| Particle Size Distribution | Laser Diffraction | Analyzes scattered laser light intensity to determine size distribution of suspended particles. |
| Microbial Limits (Total Aerobic Count) | Plate Count Agar (PCA) Method | Quantifies viable aerobic microorganisms by colony formation on nutrient agar after incubation. |
| Yeast and Mold Count | Dichloran Rose Bengal Chloramphenicol (DRBC) Agar | Selective enumeration of yeasts and molds using inhibitory and differential agar medium. |
| Pesticide Residues | GC-MS or LC-MS/MS | Multi-residue analysis using chromatographic separation followed by tandem mass spectrometric detection. |
