Manufacturing Quality Control of Fucoidan
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Assessment of physical form and color under controlled lighting conditions |
| Solubility in Water | Gravimetric Dissolution Test | Sample is dispersed in water and insoluble residue is filtered and weighed |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying at 105 C | Mass loss after drying at specified temperature reflects moisture and volatile content |
| Ash Content | Dry Ashing at 550 C followed by Gravimetry | Inorganic residue remaining after high-temperature combustion is weighed |
| Protein Content | Lowry or Bradford Assay | Quantification based on colorimetric reaction with protein-specific reagents |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS or ICP-OES | Multi-element detection via plasma ionization and mass/atomic emission spectroscopy |
| Sulfate Ester Content | Ion Chromatography with Conductivity Detection | Separation and quantification of sulfate ions released by acid hydrolysis |
| Total Carbohydrate Content | Phenol-Sulfuric Acid Assay | Colorimetric measurement of carbohydrate-derived furfural derivatives at 490 nm |
| Viscosity (1% w/v solution) | Rotational Viscometry | Shear stress response measured under defined temperature and shear rate conditions |
| pH (1% w/v solution) | Potentiometric pH Measurement | Hydrogen ion activity determined using calibrated glass electrode |
| Microbial Limits | Membrane Filtration and Plate Count | Viable aerobic microorganisms enumerated on appropriate agar media |
| Residual Solvents (e.g., ethanol, acetone) | Gas Chromatography with FID | Separation and quantification based on retention time and flame ionization response |
