Industrial Applications of cyanidin
| Industry | Application | Process |
|---|---|---|
| Food Industry | Natural food colorant (e.g., for confectionery, beverages, jellies, dairy products) | Extracted from plant raw materials and added after purification |
| Cosmetics | Pigment component in color cosmetics (e.g., lipsticks, eyeshadows) and skincare products | Blended with other formulation ingredients |
| Pharmaceuticals | Antioxidant or anti-inflammatory agent (in certain dietary supplements or drugs) | Chemically synthesized or biologically extracted |
| Textile Dyeing & Printing | Natural dye for coloring silk, cotton, linen, and other fabrics | Direct dyeing or mordant dyeing using plant extracts |
| Research | pH indicator (color changes with acidity/alkalinity) or model compound for photostability studies | Laboratory synthesis or standard solution preparation |
| Agriculture | Component of certain plant growth regulators or abiotic stress resistance enhancers | Produced via biotechnological processes |
Manufacturing Quality Control of cyanidin
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies anthocyanin content by separation on a reversed-phase column and UV-Vis detection at 520 nm. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration with iodine-based reagent. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by weight measurement. |
| Heavy Metals (Pb, Cd, As, Hg) | ICP-MS | Simultaneously quantifies trace heavy metals using plasma ionization and mass spectrometric detection. |
| Arsenic | Hydride Generation-AAS | Converts arsenic to arsine gas, then measures atomic absorption at 193.7 nm. |
| Lead | Graphite Furnace-AAS | Atomizes lead in a graphite furnace and measures absorption at 283.3 nm for high sensitivity. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after ignition with sulfuric acid treatment to convert carbonates to sulfates. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines hydrogen ion activity using calibrated glass electrode and reference electrode. |
| Solvent Residues (e.g., methanol, acetone) | GC-FID | Separates and quantifies residual solvents by gas chromatography with flame ionization detection. |
| Microbial Contamination | Plate Count Method | Estimates viable aerobic microorganisms by colony formation on nutrient agar after incubation. |
| Color Value (Absorbance at 520 nm) | UV-Vis Spectrophotometry | Measures specific absorbance of standardized solution at 520 nm as indicator of chromophore concentration. |
| Related Substances | HPLC-DAD | Identifies and quantifies degradation products and impurities using diode array detection across multiple wavelengths. |
