| Industry | Application | Process |
|---|---|---|
| Food Industry | Emulsifier | Dissolved in water or oil to form a stable emulsion system |
| Pharmaceutical Industry | Drug delivery excipient | Blended with active pharmaceutical ingredients to formulate capsules or tablets |
| Cosmetics Industry | Humectant | Dissolved in water and incorporated as a moisturizing agent into skincare formulations |
| Plastics Industry | Plasticizer | Blended with plastic substrates to enhance flexibility and elongation |
| Textile Industry | Coating agent | Applied in textile surface treatment to improve abrasion resistance and water repellency |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Protein Content | Kjeldahl Nitrogen Determination | Measures total nitrogen content and converts to protein using a standard nitrogen-to-protein conversion factor (6.38 for casein). |
| Moisture Content | Gravimetric Oven Drying | Determines loss in weight after drying at 105 C until constant mass is achieved. |
| Ash Content | Gravimetric Muffle Furnace Ashing | Measures residual inorganic matter after incineration at 550 C. |
| pH | Potentiometric pH Measurement | Measures hydrogen ion activity in a 1% aqueous solution using a calibrated pH electrode. |
| Solubility | Visual Turbidity Assessment | Evaluates clarity and absence of insoluble particles in a standardized aqueous solution under specified conditions. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies lead concentration by measuring absorbance of ground-state atoms in a flame or graphite furnace. |
| Arsenic | Hydride Generation Atomic Absorption Spectroscopy (HG-AAS) | Converts arsenic to volatile hydride, then measures atomic absorption after atomization. |
| Sodium Content | Flame Photometry | Measures intensity of emitted light at characteristic wavelength when sodium ions are excited in a flame. |
| Total Plate Count | Standard Plate Count Agar Culture | Estimates viable aerobic mesophilic microorganisms by colony formation on nutrient agar after incubation. |
| Yeast and Mold Count | Dichloran Rose Bengal Chloramphenicol Agar (DRBC) | Selective enumeration of yeasts and molds based on colony morphology and growth inhibition of bacteria. |
| Coliforms | Most Probable Number (MPN) Method | Statistical estimation of coliform density based on lactose fermentation in selective broth tubes. |
| Residual Solvents (e.g., ethanol) | Gas Chromatography (GC) | Separates and quantifies volatile organic residues using a capillary column and flame ionization detection. |
