Manufacturing Quality Control of POLYGALACTURONIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Acid Value | Acid-Base Titration | Neutralization of free carboxylic acid groups with standardized NaOH solution using phenolphthalein indicator. |
| Galacturonic Acid Content | UV-Vis Spectrophotometry after carbazole reaction | Quantification based on colorimetric reaction of galacturonic acid with carbazole under acidic conditions, measured at 530 nm. |
| Degree of Esterification (DE) | Potentiometric Titration | Two-stage titration to distinguish esterified vs. free carboxyl groups; DE calculated from NaOH consumption before and after saponification. |
| Ash Content | Gravimetric Analysis (Ignition at 525 C) | Residue mass after incineration at controlled temperature, representing inorganic mineral content. |
| Moisture Content | Karl Fischer Titration | Electrochemical determination of water content via iodine-sulfur dioxide reaction in anhydrous methanol medium. |
| Heavy Metals (Pb, Cd, As, Hg) | ICP-MS | Multi-element quantification by measuring metal ion signals after plasma ionization and mass separation. |
| Arsenic | Hydride Generation-AAS | Conversion of arsenic to arsine gas, followed by atomic absorption measurement at 193.7 nm. |
| Loss on Drying | Gravimetric Analysis (105 C, 2 h) | Mass loss after drying at constant temperature, indicating volatile and residual solvent content. |
| Viscosity (1% w/v, pH 3.0) | Capillary Viscometry | Measurement of flow time through calibrated capillary tube under gravity, converted to kinematic viscosity. |
| pH (1% w/v solution) | pH Potentiometry | Direct measurement using calibrated glass electrode in aqueous dispersion. |
| Microbial Contamination (Total Aerobic Count) | Plate Count Agar Method | Enumeration of viable aerobic bacteria after incubation on nutrient agar plates. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern from dispersed particles to determine size distribution profile. |
