Manufacturing Quality Control of Calcium sorbate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration with HCl | Direct titration of sorbate ion with standardized hydrochloric acid using potentiometric or phenolphthalein endpoint detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals by flame or graphite furnace AAS after acid digestion and matrix matching. |
| Loss on Drying | Gravimetric (Thermogravimetric) | Mass loss measured after drying at 105 °C to constant weight, reflecting volatile content and residual moisture. |
| Residue on Ignition | Gravimetric (Sulfated Ash) | Mass of inorganic residue remaining after high-temperature ignition (700–800 °C) following sulfuric acid treatment. |
| Chloride Impurity | Potentiometric Titration with AgNO₃ | Titration with silver nitrate using a silver indicator electrode; detects chloride ions via precipitation of AgCl. |
| Calcium Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantitative determination of calcium by measuring characteristic atomic emission lines after acid dissolution. |
| Sorbic Acid Content | High-Performance Liquid Chromatography (HPLC-UV) | Separation on reversed-phase C18 column followed by UV detection at 254 nm to quantify free sorbic acid. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Measurement of hydrogen ion activity in a 1% w/v aqueous solution using calibrated pH electrode. |
| Insoluble Matter | Gravimetric Filtration | Filtration through pre-weighed sintered glass crucible, drying, and weighing of retained residue. |
| Microbial Limits | Membrane Filtration / Plate Count | Enumeration of aerobic mesophilic microorganisms following membrane filtration and incubation on soybean-casein digest agar. |
| Arsenic | Hydride Generation Atomic Absorption Spectroscopy (HG-AAS) | Conversion of arsenic to arsine gas, swept into graphite furnace AAS for sensitive quantification. |
| Sulfate Impurity | Barium Sulfate Gravimetric Method | Precipitation as BaSO₄ in acidic medium, followed by filtration, ignition, and gravimetric determination. |
| Iron (Fe) | Colorimetric (1,10-Phenanthroline) | Reduction of Fe³⁺ to Fe²⁺ and complex formation with 1,10-phenanthroline; absorbance measured at 510 nm. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution at specified concentration and wavelength (e.g., sodium D-line). |
