Manufacturing Quality Control of Monostearin
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification Test | Infrared Spectroscopy (IR) | The infrared absorption spectrum of the sample is measured using an infrared spectrophotometer and compared with standard spectra to confirm the presence of characteristic functional groups (e.g., ester, hydroxyl groups), used for identifying glyceryl monostearate. |
| Acid Value | Titration Method (GB/T 5530 or similar standard) | The sample is dissolved in neutral ethanol or isopropanol, phenolphthalein is used as an indicator, and free fatty acids are titrated with standard potassium hydroxide solution. The acid value is calculated as milligrams of KOH consumed per gram of sample, reflecting free acid content. |
| Saponification Value | Titration Method (GB/T 5534 or similar standard) | The sample is refluxed with excess ethanolic potassium hydroxide solution for saponification, and the remaining base is titrated with standard hydrochloric acid. The saponification value is calculated by comparison with a blank, expressed as mg KOH per gram of sample, reflecting total ester content. |
| Hydroxyl Value | Acetylation-Titration Method (GB/T 7383 or similar standard) | The sample is acetylated with acetic anhydride, and the hydrolyzed product is titrated with standard potassium hydroxide to determine the amount of acetic acid produced. The hydroxyl value is calculated as KOH mg equivalent per gram of sample, representing the content of free hydroxyl groups. |
| Monoglyceride Content | High-Performance Liquid Chromatography (HPLC) | Using a reversed-phase C18 column with methanol-water or acetonitrile-water as mobile phase, monoglycerides, diglycerides, and triglycerides are separated and quantified by refractive index or evaporative light scattering detector (ELSD), assessing product purity. |
| Moisture | Karl Fischer Titration | Karl Fischer reagent reacts quantitatively with water in the sample. Moisture content is determined by potentiometric or volumetric titration, suitable for trace moisture analysis. |
| Melting Point | Capillary Method or Digital Melting Point Apparatus | The sample is placed in a capillary tube, heated gradually in a controlled temperature device, and the initial and final melting temperatures are observed. The typical melting point range for glyceryl monostearate is approximately 78–82°C. |
| Color | Visual Color Comparison or Colorimeter Method | The sample is dissolved in hot ethanol or chloroform, compared with standard color solutions visually, or measured using a colorimeter for yellowness index (YI) to assess color purity. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After sample digestion, AAS or ICP-MS is used to determine heavy metal elements such as lead, arsenic, cadmium, and mercury, ensuring compliance with food safety or pharmaceutical limits. |
| Arsenic | Gutzeit Method or Atomic Fluorescence Spectrometry (AFS) | Arsenic content is determined by the Gutzeit visual comparison method or more sensitive AFS to control toxic element residues. |
