Manufacturing Quality Control of Vanillin
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Purity/Content Determination | High-Performance Liquid Chromatography (HPLC) | Using a reversed-phase C18 chromatographic column, with methanol-water or acetonitrile-water as the mobile phase, and a UV detector (typically at 280 nm or 347 nm wavelength) to detect the vanillin peak area. The content is calculated using external standard or internal standard methods, offering high sensitivity, accuracy, and good repeatability. |
| Melting Point Determination | Capillary Melting Point Method | Dry sample is placed into a melting point capillary tube and heated gradually in a melting point apparatus. The initial and final melting temperatures are recorded. The standard melting point of vanillin is approximately 81–83 °C, used to assess its purity and crystalline state. |
| Appearance and Color | Visual Colorimetric Method | Under specified lighting conditions, the sample is compared with a standard color solution or against a white background to observe its color (usually white to slightly yellow crystalline powder), evaluating the presence of obvious impurities or degradation. |
| Dry Loss | Drying Loss Method | A certain amount of sample is weighed and dried at 105 °C until constant weight. The percentage of mass loss is calculated, used to control moisture and other volatile impurities. |
| Residue on Ignition (Ash Content) | High-Temperature Incineration Method | After carbonization, the sample is incinerated in a high-temperature furnace at 700–800 °C until constant weight. The residual inorganic material is weighed to evaluate the content of inorganic impurities. |
| Heavy Metal Limit | Atomic Absorption Spectrometry (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After sample digestion, AAS or ICP-MS is used to determine the content of heavy metals such as lead, arsenic, cadmium, and mercury, ensuring compliance with pharmacopoeia or food additive safety standards. |
| Related Substances (Impurities) | Gradient Elution HPLC Method | A gradient elution program is used to separate the vanillin main peak from possible by-products (such as ethyl vanillin, vanillic acid, guaiacol, etc.). The total impurity content and individual impurity limits are controlled using peak area normalization or correction factor-based main component self-comparison method. |
| pH Value (Aqueous Solution) | pH Meter Measurement Method | A 1% aqueous solution of vanillin is prepared, and its pH value is measured using a calibrated pH meter. It should generally be weakly acidic (pH around 4.5–6.5), reflecting the presence of acidic or basic impurities. |
