| Food | Additive | Applied to control crystallization and improve product quality |
Manufacturing Quality Control of Di-p-anisoyl-D-tartaric acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 220-254 nm, comparing peak area to a certified reference standard. |
| Enantiomeric Excess (ee) | Chiral HPLC | Separation on a chiral stationary phase followed by UV detection; ee calculated from peak area ratio of enantiomers. |
| Loss on Drying (LOD) | Gravimetric Thermogravimetry | Sample heated at 105 C for 2 h; % LOD calculated from weight loss relative to initial mass. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection; quantitation against external calibration standards for common solvents. |
| Heavy Metals (as Pb) | ICP-OES | Digestion followed by inductively coupled plasma optical emission spectrometry; total heavy metals reported as lead equivalent. |
| Chloride Impurity | Ion Chromatography | Anion-exchange chromatography with conductivity detection; quantitation via external calibration with NaCl standard. |
| Sulfate Impurity | Turbidimetric Method | Reaction with barium chloride under acidic conditions; sulfate concentration determined from turbidity measurement. |
| Water Content | Karl Fischer Titration | Coulometric or volumetric titration with iodine-based reagent; water quantified by electrochemical or stoichiometric endpoint detection. |
| Melting Point | Capillary Melting Point Apparatus | Solid sample heated in capillary tube; temperature range at which solid transitions to liquid is recorded. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light at 20 C using sodium D-line (589 nm); reported as [alpha]D value. |
| Particle Size Distribution | Laser Diffraction | Dry or wet dispersion followed by laser scattering analysis; size distribution reported as D10, D50, D90 values. |
| Microbial Limits | Membrane Filtration | Sample filtration, membrane transfer to appropriate agar media, incubation, and colony enumeration per USP <61>. |
