Industrial Applications of Zinc L-lactate
| Industry | Application | Process |
|---|---|---|
| Food Industry | Food additive (nutrient fortifier, acidity regulator, preservative) | Added as a zinc source to dairy products, beverages, and infant formula via dry blending or solution mixing; compliant with standards such as GB 14880-2012 |
| Pharmaceutical Industry | Active pharmaceutical ingredient in oral zinc supplementation formulations (e.g., tablets, oral solutions) | Processed using wet granulation, direct compression, or solution preparation, followed by blending with excipients to produce solid or liquid dosage forms |
| Cosmetics Industry | Humectant, antimicrobial agent, and zinc source in skin care products | Incorporated into the aqueous phase during emulsification or cooling for use in toners, lotions, and masks; effective within a pH range of 4.0–6.5 |
| Feed Industry | Trace mineral feed additive (providing bioavailable zinc) | Uniformly blended with premixes prior to incorporation into complete feed, or applied onto pelleted feed surfaces via spray coating |
Manufacturing Quality Control of Zinc L-lactate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (ZnC6H10O6 content) | Acid-Base Titration | Direct titration with standardized EDTA solution after pH adjustment and complexation with Zn2+; endpoint detected by metal indicator. |
| Zinc Content | Atomic Absorption Spectroscopy (AAS) | Quantification of Zn concentration based on absorption of specific wavelength light by ground-state Zn atoms in flame. |
| Heavy Metals (Pb, Cd, As, Hg) | Inductively Coupled Plasma - Optical Emission Spectrometry (ICP-OES) | Multi-element detection via characteristic atomic emission lines following acid digestion and plasma atomization/excitation. |
| Loss on Drying | Gravimetric Analysis | Mass loss measured after drying at 105 C for 2 hours under controlled conditions to determine volatile content. |
| Residue on Ignition | Gravimetric Analysis | Weight of non-volatile inorganic residue remaining after high-temperature (500-600 C) ashing of sample. |
| Chloride Impurity | Argentometric Titration (Mohr method) | Titration with standardized silver nitrate solution; endpoint indicated by formation of red Ag2CrO4 precipitate. |
| Sulfate Impurity | Barium Sulfate Gravimetric Method | Precipitation of sulfate as BaSO4 under acidic conditions, followed by filtration, drying, and weighing. |
| pH of Aqueous Solution | Potentiometric Method | Measurement of hydrogen ion activity using calibrated glass electrode and pH meter in 1% w/v aqueous suspension. |
| Specific Optical Rotation | Polarimetry | Determination of chiral purity by measuring rotation of plane-polarized light in a defined concentration and path length solution. |
| Water Content (Karl Fischer) | Volumetric Karl Fischer Titration | Quantitative reaction of water with iodine and sulfur dioxide in pyridine/methanol medium; endpoint detected electrometrically. |
| Microbial Limits | Membrane Filtration and Plate Count | Sample filtration through sterile membrane, followed by incubation on appropriate agar media and colony enumeration. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to calculate volume-based particle size distribution in dispersed suspension. |
