Industrial Applications of L-Lysine dihydrochloride
| Industry | Application | Process |
|---|---|---|
| Animal Feed Industry | Nutritional additive for animal nutrition, supplementing lysine to promote growth and improve feed conversion ratio | Incorporated into compound feed or premixes, followed by mixing, pelleting, and other processing steps to produce finished feed |
| Food Industry | Nutritional fortifier used to improve amino acid balance in food products | Added as required during food processing, e.g., in baked goods, dairy products, and infant formula |
| Pharmaceutical Industry | Pharmaceutical excipient or amino acid supplement for treating lysine deficiency or supporting treatment of herpes virus infections | Formulated into oral dosage forms (e.g., tablets, capsules) or injectables via blending, compression, or filling operations |
| Biotechnology | Component of microbial culture media to support growth of specific strains | Dissolved in culture medium solution and sterilized prior to use in cell or microbial cultivation |
| Cosmetics Industry | Skin-care ingredient with moisturizing and skin barrier repair properties | Incorporated into formulations such as emulsions and serums, followed by emulsification, homogenization, and other processing steps to yield final products |
Manufacturing Quality Control of L-Lysine dihydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (L-Lysine HCl content) | Acid-base titration | Quantifies total L-lysine dihydrochloride by neutralization with standardized NaOH using bromocresol green indicator. |
| Loss on drying | Gravimetric analysis | Measures weight loss after drying at 105 C for 2 hours to determine volatile matter and residual moisture. |
| Specific optical rotation | Polarimetry | Determines enantiomeric purity by measuring rotation of plane-polarized light at 20 C using sodium D line. |
| pH of solution (5% w/v) | Potentiometric pH measurement | Evaluates acidity/basicity of aqueous solution using calibrated pH electrode. |
| Chloride content | Argentometric titration (Mohr method) | Quantifies Cl- ions by titration with AgNO3 using potassium chromate indicator. |
| Heavy metals (as Pb) | Colorimetric sulfide precipitation | Compares sample color after reaction with thioacetamide under controlled pH to lead standard. |
| Sulfated ash | Gravimetric analysis | Measures inorganic residue after combustion with sulfuric acid treatment and ignition at 600 C. |
| Related substances | HPLC with UV detection | Separates and quantifies impurities using reversed-phase C18 column and UV detection at 200 nm. |
| Residual solvents | Gas chromatography (GC-FID) | Detects and quantifies volatile organic solvents (e.g., ethanol, acetone) using flame ionization detection. |
| Microbial limits | Membrane filtration and colony counting | Determines total aerobic microbial count and absence of specified pathogens via culture-based enumeration. |
| Particle size distribution | Laser diffraction | Measures particle size range and distribution using light scattering principles. |
| Iron content | Atomic absorption spectroscopy (AAS) | Quantifies Fe concentration by measuring absorbance of ground-state Fe atoms at 248.3 nm. |
