Industrial Applications of EC 3.4.21.14
| Industry | Application | Process |
|---|---|---|
| Food Industry | Meat tenderization, coagulation aid in cheese production, and improvement of dough extensibility in baking | Applied to meat surfaces or incorporated into marinades; used synergistically with rennet in cheese making; hydrolyzes gluten proteins in dough |
| Detergent Industry | Protein stain removal component in laundry and dishwashing detergents | Formulated as a biological enzyme additive, blended with surfactants, and active at ambient temperature up to 60°C |
| Leather Industry | Depilation and softening of raw hides | Replaces lime-sodium sulfide treatment in the liming process, reducing environmental impact |
| Feed Industry | Enhancement of digestibility of plant-based protein feed | Incorporated prior to pelleting of compound feed; partially inactivated by thermal processing but retains residual activity |
| Pharmaceutical Industry | Wound debridement agent (topical use) and proteolytic step in insulin production | Formulated into debriding gels or sprays; cleaves precursor proteins (e.g., proinsulin) during recombinant human insulin synthesis |
Manufacturing Quality Control of EC 3.4.21.14
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Enzyme Activity | Spectrophotometric Assay (Azo-casein or Suc-AAPF-pNA substrate) | Measures rate of substrate hydrolysis by monitoring absorbance change at specific wavelength due to release of colored product. |
| Protein Content | Lowry or Bradford Assay | Quantifies total protein based on colorimetric reaction with copper ions (Lowry) or Coomassie dye binding (Bradford). |
| Moisture Content | Gravimetric Loss on Drying | Determines water content by measuring mass loss after controlled heating under specified temperature and time. |
| pH (1% w/v aqueous solution) | Potentiometric Titration | Measures hydrogen ion activity using calibrated pH electrode in standardized suspension. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS or ICP-OES | Quantifies trace metal elements by atomization and ionization in plasma followed by mass or optical detection. |
| Residual Solvents | Gas Chromatography (GC-FID) | Separates and quantifies volatile organic solvents based on retention time and flame ionization response. |
| Microbial Contamination (Total Aerobic Count) | Plate Count Agar (PCA) Method | Estimates viable aerobic microorganisms by colony formation on nutrient agar after incubation. |
| Yeasts and Molds | Sabouraud Dextrose Agar (SDA) Method | Detects and enumerates yeasts and molds via colony growth on selective medium under controlled conditions. |
| Coliforms | Most Probable Number (MPN) or Membrane Filtration | Detects coliform bacteria based on lactose fermentation and gas production in selective broth or on membrane filters. |
| Particle Size Distribution | Laser Diffraction | Determines particle size distribution by analyzing angular variation in intensity of scattered laser light. |
| Bulk Density | Graduated Cylinder Method (ASTM D1895) | Measures mass per unit volume of freely settled powder in a standardized cylinder. |
| Residual Host Cell Proteins | ELISA | Quantifies trace host proteins using antigen-antibody binding with enzyme-linked detection and colorimetric readout. |
