Industrial Applications of Lysozyme hydrochloride
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Used as a stabilizer and pH adjuster for lysozyme in the preparation of lysozyme injection solutions, ophthalmic solutions, and other formulations | Dissolve lysozyme hydrochloride in water for injection under aseptic conditions, sterilize by filtration through a 0.22 μm membrane filter, and fill into sterile containers |
| Food | Used as a food-grade preservative and freshness enhancer to inhibit growth of Gram-positive bacteria and extend shelf life of dairy and egg products | Add at 0.01–0.1% (w/w) to liquid milk, cheese, or egg liquids prior to pasteurization; maintain pH at 5.5–6.5 to preserve lysozyme activity |
| Biotechnology | Used as a component of cell lysis buffers to enhance lysozyme-mediated hydrolysis efficiency against bacterial cell walls—particularly those of Gram-positive bacteria | Add lysozyme to Tris-HCl or phosphate buffer to a final concentration of 1–10 mg/mL, adjust pH to 6.0–7.0 with hydrochloric acid, and incubate at 37°C for 15–30 minutes to achieve efficient lysis |
| Cosmetics | Used as a mild antimicrobial agent and keratin regulator in acne-treating and oil-control skincare products | Formulate into gels or emulsions with glycerin, hyaluronic acid, etc., at pH 5.0–6.0 and lysozyme concentration of 0.005–0.05% (w/w); avoid high-temperature sterilization to retain enzymatic activity |
Manufacturing Quality Control of Lysozyme hydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Lysozyme Activity) | Enzymatic Activity Assay (Micrococcus lysodeikticus Lysis) | Measures enzymatic activity by monitoring turbidity decrease of Micrococcus lysodeikticus cell suspension at 450 nm. |
| Protein Content | UV-Vis Spectrophotometry (280 nm) | Quantifies protein based on absorbance of aromatic amino acids (Trp, Tyr) at 280 nm using extinction coefficient. |
| pH | Potentiometric Titration (pH Meter) | Determines hydrogen ion concentration using calibrated glass electrode in aqueous solution. |
| Residual Solvents | Gas Chromatography (GC-FID) | Separates and quantifies volatile organic solvents based on retention time and flame ionization detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously detects trace metal elements by measuring characteristic atomic emission spectra after plasma excitation. |
| Chloride Ion (Cl-) | Argentometric Titration (Mohr Method) | Titrates chloride with standardized silver nitrate solution using potassium chromate indicator for endpoint detection. |
| Loss on Drying (LOD) | Gravimetric Analysis (Thermogravimetry) | Measures mass loss after drying at 105 C to determine volatile content including water and residual solvents. |
| Microbial Contamination | Membrane Filtration and Plate Count | Filters sample through membrane, incubates on appropriate agar media, and enumerates colony-forming units. |
| Endotoxin Level | Limulus Amebocyte Lysate (LAL) Assay | Detects bacterial endotoxins via coagulation cascade activation in horseshoe crab lysate, measured turbidimetrically or chromogenically. |
| Related Proteins/Impurities | SDS-PAGE | Separates proteins by molecular weight under denaturing conditions; visualized by Coomassie staining to assess purity and degradation. |
| Residual Host Cell Proteins | ELISA | Uses antibody-based capture and detection to quantify host cell protein impurities specific to production system. |
| Sterility | Membrane Filtration and Incubation (USP <71>) | Filters sample under aseptic conditions into fluid thioglycollate and soybean-casein digest media, followed by incubation and growth observation. |
