Manufacturing Quality Control of κ-Carrageenan
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Assessment of physical form, color, and presence of foreign particles under controlled lighting. |
| Odor | Sensory Evaluation | Trained personnel evaluate characteristic odor; absence of off-odor indicates purity. |
| Solubility in Water | Gravimetric Dissolution Test | Sample is dispersed in hot water and filtered; insoluble residue is dried and weighed. |
| Gel Strength | Texture Analyzer (Bloom Gelometer) | Force required to depress a standardized gel plug with a specified probe is measured. |
| Viscosity | Rotational Viscometer | Shear stress response of aqueous solution at defined concentration, temperature, and shear rate is quantified. |
| Sulfate Content | Ion Chromatography (IC) or Gravimetric BaSO4 Precipitation | Sulfate ions are separated and quantified by conductivity detection or precipitated as BaSO4 for mass determination. |
| Ash Content | Gravimetric Ashing | Sample is incinerated at 525-550 C; residual inorganic matter is weighed after cooling. |
| Loss on Drying (LOD) | Thermogravimetric Analysis (TGA) or Oven Drying | Mass loss upon heating at 105 C for 3 h reflects moisture and volatile content. |
| Heavy Metals (Pb, As, Cd, Hg) | ICP-MS or ICP-OES | Digestion followed by multi-element quantification using plasma ionization and mass/atomic emission detection. |
| Microbial Limits | Membrane Filtration / Plate Count | Viable aerobic bacteria, yeasts, and molds are enumerated on selective agar media after filtration or direct plating. |
| pH of 1% Aqueous Solution | Potentiometric pH Measurement | pH electrode measures hydrogen ion activity in a standardized suspension after equilibration. |
| Protein Content | Kjeldahl Nitrogen Determination | Organic nitrogen is digested, distilled, and titrated; protein is estimated using nitrogen-to-protein conversion factor. |
