Manufacturing Quality Control of PROTEASE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Enzyme Activity | Spectrophotometric Assay (UV-Vis) | Measures hydrolysis rate of casein substrate at 275 nm; activity calculated from tyrosine release using standard curve. |
| Protein Content | Lowry Method | Quantifies protein via Cu2+ complex formation with peptide bonds and aromatic residues, measured at 750 nm. |
| Moisture Content | Gravimetric Analysis (Oven Drying) | Determines weight loss after drying at 105 C until constant mass. |
| Ash Content | Gravimetric Analysis (Muffle Furnace) | Measures inorganic residue remaining after combustion at 550 C. |
| pH (5% aqueous solution) | Potentiometric Titration | Uses calibrated pH electrode to measure hydrogen ion activity in standardized suspension. |
| Heavy Metals (Pb, Cd, As, Hg) | ICP-MS | Quantifies trace metal concentrations by ionization in plasma and mass spectrometric detection. |
| Arsenic | Hydride Generation AAS | Converts arsenic to volatile hydride, then measures atomic absorption at 193.7 nm. |
| Microbial Contamination (Total Aerobic Count) | Plate Count Agar (PCA) Method | Enumerates viable aerobic bacteria by colony formation on nutrient agar after incubation at 30 C for 72 h. |
| Yeast and Mold Count | Dichloran Rose Bengal Chloramphenicol (DRBC) Agar | Selective enumeration based on growth inhibition of bacteria and enhanced fungal colony visibility. |
| Residual Solvents (e.g., ethanol, acetone) | Gas Chromatography (GC-FID) | Separates and quantifies volatile organic solvents using flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Measures scattering pattern of dispersed particles to calculate size distribution based on Mie theory. |
| Specific Absorbance (A1cm1%) | UV-Vis Spectrophotometry | Determines absorbance per unit concentration and path length at 280 nm to assess purity and consistency. |
