Industrial Applications of CURDLAN
| Industry | Applications | Processing |
|---|---|---|
| Food Industry | Thickener, stabilizer, gelling agent | Applied in low-calorie foods, vegetarian products, jellies, puddings, and dairy alternatives to form thermoreversible gels via heat-induced gelation |
| Pharmaceutical Industry | Controlled-release drug carrier, tissue engineering scaffold material | Used to prepare microspheres and hydrogels for controlled drug delivery or cell culture, leveraging its biocompatibility and thermogelling properties |
| Cosmetics Industry | Humectant, thickener, film-forming agent | Incorporated into emulsions, masks, and gels to enhance texture and formulation stability |
| Biotechnology | Cell encapsulation and immobilized enzyme carrier | Encapsulates viable cells or enzymes via mild thermal gelation for use in bioreactors or biosensors |
| Agriculture | Seed coating, controlled-release fertilizer carrier | Forms a protective gel layer to regulate moisture and nutrient release |
Manufacturing Quality Control of CURDLAN
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Assessment of physical form, color, and homogeneity under controlled lighting conditions. |
| Moisture Content | Karl Fischer Titration | Quantitative determination of water content based on iodine-sulfur dioxide redox reaction in pyridine-methanol medium. |
| Ash Content | Gravimetric Analysis (Ignition at 550 C) | Residue mass after high-temperature incineration reflects inorganic mineral content. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Hydrogen ion activity measured using calibrated glass electrode in standardized suspension. |
| Viscosity (1% solution, 25 C) | Rotational Viscometry | Shear stress response to controlled rotational speed determines apparent viscosity. |
| Gel Strength | Texture Analyzer (Compression Test) | Force required to compress a standardized gel cylinder quantifies mechanical strength. |
| Protein Content | Kjeldahl Nitrogen Determination | Total nitrogen converted to ammonia, distilled, and titrated; multiplied by protein conversion factor. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal ions via absorption of characteristic wavelength light by ground-state atoms in flame. |
| Arsenic Content | Hydride Generation AAS (HG-AAS) | Arsenic reduced to volatile arsine gas, swept into quartz cell for atomic absorption measurement. |
| Microbial Limits | Membrane Filtration and Plate Count | Viable aerobic bacteria and molds/yeasts enumerated on selective agar media after filtration and incubation. |
| Residual Solvents (e.g., ethanol) | Gas Chromatography (GC-FID) | Separation and detection of volatile organic residues using flame ionization detector. |
| Purity (by HPLC) | High-Performance Liquid Chromatography (HPLC-RID) | Quantification of main component relative to reference standard using refractive index detection. |
