Industrial Applications of Calcium dihydrogen di-L-aspartate
| Industry | Application | Process |
|---|---|---|
| Food Industry | Calcium fortificant (for beverages, dietary supplements, dairy products, etc.) | Directly blended or dissolved into the final product as a nutritional additive |
| Pharmaceutical Industry | Calcium supplement (for osteoporosis treatment and bone health support) | Formulated into tablets, capsules, or oral solutions via compression, encapsulation, or dissolution |
| Dietary Supplement Industry | Dietary supplement (a highly bioavailable calcium source for calcium-deficient populations) | Blended with other ingredients and processed into capsules, powders, or gummies |
| Agriculture | Foliar fertilizer or soil conditioner (to supply calcium nutrition and enhance crop stress resistance) | Applied via foliar spray or irrigation after mixing with water or fertilizers |
Manufacturing Quality Control of Calcium dihydrogen di-L-aspartate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Ca content) | Complexometric Titration with EDTA | Calcium ions form a stable complex with EDTA at pH 10; endpoint detected by color change of Eriochrome Black T indicator. |
| Assay (L-Aspartic Acid content) | Acid-Base Titration | Free carboxylic acid groups are titrated with standardized NaOH using phenolphthalein indicator. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Multi-element quantification via atomic emission from plasma-excited sample atoms. |
| Loss on Drying | Gravimetric Analysis | Mass loss measured after drying at 105 C for 2 hours under controlled atmospheric conditions. |
| Residue on Ignition | Weight Method | Inorganic residue mass determined after charring and ashing at 600 C in a muffle furnace. |
| Chloride | Potentiometric Titration with AgNO3 | Chloride ions react with silver nitrate to form AgCl precipitate; endpoint detected by silver ion-selective electrode. |
| Sulfate | Turbidimetric Method | Barium sulfate precipitate formed in acidic medium; concentration determined by light scattering measurement. |
| pH (1% aqueous solution) | pH Potentiometry | Hydrogen ion activity measured using calibrated glass electrode in aqueous suspension. |
| Specific Optical Rotation | Polarimetry | Rotation of plane-polarized light measured at 20 C using sodium D-line; indicates enantiomeric purity of L-aspartic acid moiety. |
| Related Substances | HPLC-UV | Separation on reversed-phase column followed by UV detection at 210 nm to quantify impurities and degradation products. |
| Microbial Limits | Membrane Filtration | Viable microorganisms retained on filter membrane, then cultured on appropriate agar media for enumeration. |
| Particle Size Distribution | Laser Diffraction | Scattering pattern of laser beam through dispersed particles analyzed to calculate size distribution. |
