| Industry | Application | Process |
|---|---|---|
| Food Industry | Antioxidant; nutritional fortificant (source of vitamin C) | Added to beverages, dairy products, and baked goods to prevent oxidative spoilage and supplement vitamin C |
| Animal Feed Industry | Stabilized vitamin C source for animal feed additives | Incorporated into poultry, livestock, and aquaculture feeds to enhance animal immunity and growth performance |
| Cosmetics Industry | Skincare active ingredient (antioxidant, skin-brightening) | Formulated into lotions, serums, and creams to inhibit melanin synthesis and delay skin aging |
| Pharmaceutical Industry | Pharmaceutical excipient or raw material for vitamin C supplements | Used in the manufacture of oral solid dosage forms or injectables to deliver bioavailable vitamin C |
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample color and physical state (typically white to off-white crystalline powder), ensuring no visible foreign particles. |
| Identification | Infrared Spectroscopy (IR) | Compare the infrared spectrum with that of a reference standard; characteristic absorption peaks should match to confirm molecular structure. |
| Identification | High-Performance Liquid Chromatography (HPLC) | Retention time should be identical to that of the reference standard, providing additional confirmation of the main component's identity. |
| Assay | High-Performance Liquid Chromatography (HPLC) | Utilize a C18 reversed-phase column with a UV detector (e.g., at 210 nm or 265 nm) and the external standard method to calculate the content of the main component. |
| Loss on Drying | Drying Method (105°C to constant weight) | Dry the sample in an oven until constant weight is achieved; calculate the percentage of mass loss to control moisture and volatile substances. |
| Residue on Ignition | High-Temperature Ashing | Incinerate the sample in a muffle furnace (600–800°C) until constant weight is reached; determine the residual inorganic impurities. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After digestion, measure limiting elements such as lead, arsenic, cadmium, and mercury; comply with pharmacopoeial or feed additive safety standards. |
| pH Value | pH Meter Measurement | Prepare a solution of specified concentration (e.g., 1%) and measure its pH; it should fall within the specified range (e.g., 5.0–7.0). |
| Solubility | Solubility Test | Observe solubility in specified solvents (e.g., water, ethanol); results should conform to product specification requirements. |
| Related Substances / Impurities | HPLC with Gradient Elution | Optimize chromatographic conditions to separate and quantify individual impurity peaks; control limits for individual and total impurities (e.g., ≤1.0%). |
| Optical Rotation | Polarimeter Measurement | Measure the optical rotation of a specified concentration solution to verify optical purity (should be levorotatory, consistent with L-configuration). |
| Phosphate Content | Molybdenum Blue Colorimetry or Ion Chromatography | Quantify phosphate groups via colorimetric reaction or chromatographic separation to verify the integrity of the phosphate ester structure. |
| Tri-cyclohexylammonium Content | Acid-Base Titration or Ion Chromatography | Determine the content of tri-cyclohexylammonium via cation exchange or titration methods to ensure correct salt form ratio. |
| Microbial Limits | Pharmacopoeial Microbiological Testing Methods | Perform microbial testing according to the Chinese Pharmacopoeia or relevant standards to detect aerobic bacteria, molds, yeasts, and specified control organisms, ensuring hygienic safety. |
