Manufacturing Quality Control of Steviol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Steviol Glycosides) | HPLC-UV | Separation and quantification using reversed-phase HPLC with UV detection at 205 nm based on retention time and peak area calibration against reference standards. |
| Related Substances | HPLC-UV | Identification and quantification of structurally related impurities by comparison of retention times and peak areas with reference compounds or threshold-based reporting. |
| Loss on Drying | Gravimetric (Oven Drying) | Mass loss measured after drying a sample at 105 C for 2 hours under atmospheric pressure, reflecting volatile content including moisture and solvents. |
| Residue on Ignition | Gravimetric (Sulfated Ash) | Mass of inorganic residue remaining after charring and incineration at 600-700 C, indicating inorganic impurities and metallic contaminants. |
| Heavy Metals (as Pb) | AAS or ICP-OES | Quantification of total heavy metals by atomic absorption spectroscopy or inductively coupled plasma optical emission spectrometry after acid digestion. |
| Arsenic | Hydride Generation-AAS | Conversion of arsenic to arsine gas followed by atomic absorption detection, providing selective and sensitive quantification. |
| Lead | Graphite Furnace AAS | Atomization of digested sample in graphite furnace with electrothermal heating for highly sensitive lead determination. |
| Microbial Enumeration (Total Aerobic Count) | Plate Count Agar (PCA) Method | Viable aerobic bacteria quantified by colony formation on nutrient agar after incubation at 30-35 C for 48-72 hours. |
| Yeast and Mold Count | Sabouraud Dextrose Agar (SDA) Method | Enumeration of yeasts and molds by colony formation on SDA after incubation at 20-25 C for 5-7 days. |
| pH (1% aqueous solution) | Potentiometric (pH meter) | Measurement of hydrogen ion activity in a 1% w/v aqueous solution using calibrated glass electrode pH meter. |
| Specific Optical Rotation | Polarimetry | Determination of rotation angle of plane-polarized light passing through a solution, indicative of chiral purity and identity. |
| Solvent Residues (e.g., Ethanol, Acetone) | GC-FID | Separation and quantification of residual solvents using gas chromatography with flame ionization detection and internal standard calibration. |
