Manufacturing Quality Control of Cochineal
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Color Value (Absorbance at 494 nm) | UV-Vis Spectrophotometry | Measures absorbance of standardized solution at 494 nm to quantify color intensity relative to reference standard. |
| Moisture Content | Karl Fischer Titration | Quantifies water content via coulometric or volumetric titration using iodine-based reagent. |
| Ash Content | Gravimetric Analysis (Ignition at 550 C) | Determines inorganic residue after high-temperature ignition and weighing of residual ash. |
| Heavy Metals (Pb, As, Cd, Hg) | ICP-MS or ICP-OES | Simultaneously quantifies trace heavy metals after acid digestion by measuring elemental emission or mass signals. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines hydrogen ion activity using calibrated glass electrode in a defined aqueous suspension. |
| Loss on Drying | Thermogravimetric Analysis (105 C, 2 h) | Measures mass loss after drying under controlled temperature and time to assess volatile content. |
| Total Plate Count | Standard Plate Count (ISO 4833-1) | Quantifies viable aerobic mesophilic microorganisms by colony enumeration on agar medium. |
| Yeast and Mold Count | Dichloran Rose Bengal Chloramphenicol Agar (DRBC) | Enumerates yeasts and molds via selective culture and colony counting under controlled incubation. |
| Residual Solvents (e.g., Ethanol, Acetone) | Gas Chromatography (GC-FID) | Separates and quantifies volatile organic solvents using flame ionization detection. |
| Carmine Acid Content | HPLC-UV (C18 column, acidic mobile phase) | Quantifies carminic acid peak area against certified reference standard using reversed-phase chromatography. |
| Particle Size Distribution | Laser Diffraction | Measures scattering pattern of dispersed particles to calculate size distribution based on Mie theory. |
| Specific Optical Rotation | [alpha]D Measurement | Determines rotation angle of plane-polarized light through solution to confirm chiral purity and identity. |
