Industrial Applications of D-Lactose monohy
| Industry | Application | Process |
|---|---|---|
| Food Industry | Used as a sweetener and bulking agent in dairy products, confectionery, and baked goods | Directly incorporated into formulations and mixed with other ingredients prior to thermal or freezing processing |
| Pharmaceutical Industry | Used as a diluent, excipient, and stabilizer in tablets and capsules | Blended with active pharmaceutical ingredients and processed via wet granulation, dry granulation, or direct compression |
| Microbiology | Serves as a carbon source in culture media for lactose-fermenting microorganisms | Dissolved in water and combined with other nutrients to prepare liquid or solid culture media, followed by sterilization and inoculation |
| Cosmetic Industry | Used as a skin-conditioning and moisturizing agent | Dissolved in the aqueous phase and blended with emulsifiers, preservatives, and other components to formulate emulsions or creams |
| Biotechnology | Used as an inducer for lac operon expression in Escherichia coli | Added to fermentation broth during cultivation to trigger target protein expression |
Manufacturing Quality Control of D-Lactose monohy
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (D-Lactose Monohydrate Content) | Acid-Base Titration after Hydrolysis | Hydrolysis converts lactose to glucose and galactose, followed by titration of reducing sugars with standardized iodine solution. |
| Loss on Drying | Gravimetric Method (Thermogravimetry) | Sample is dried at 105 C for 2 hours and weight loss is measured to determine moisture content. |
| Specific Optical Rotation | Polarimetry | Measures the angle of rotation of plane-polarized light caused by chiral D-lactose in aqueous solution. |
| pH of Solution | Potentiometric pH Measurement | pH electrode measures hydrogen ion activity in a 10% w/v aqueous solution of the sample. |
| Residue on Ignition | Gravimetric Ashing | Sample is ignited at 600-700 C to oxidize organic matter; residual inorganic ash is weighed. |
| Heavy Metals (as Pb) | Colorimetric Method with Thioglycollic Acid | Heavy metals react with thioglycollic acid under buffered conditions to form colored complexes, compared visually or spectrophotometrically. |
| Sulfated Ash | Gravimetric Ashing with Sulfuric Acid Pretreatment | Sample is charred, treated with sulfuric acid, then ignited; residue represents inorganic sulfates. |
| Chlorides | Argentometric Titration (Mohr Method) | Chloride ions react with standardized silver nitrate in neutral medium; endpoint detected by brick-red silver chromate formation. |
| Sulfates | Barium Sulfate Gravimetric Method | Sulfate is precipitated as barium sulfate after acidification and addition of barium chloride, then dried and weighed. |
| Microbial Limits | Membrane Filtration and Plate Count | Sample is filtered, membrane placed on appropriate agar media, and colonies counted after incubation. |
| Related Substances | High Performance Liquid Chromatography (HPLC) | Separation and quantification of impurities (e.g., glucose, galactose, lactulose) using reversed-phase HPLC with refractive index or UV detection. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to determine volume-based particle size distribution in dispersed sample. |
