Industrial Applications of DL-Malic acid disodium salt
| Industry | Applications | Process |
|---|---|---|
| Food Industry | Acidulant, pH regulator, flavor enhancer | Directly added to beverages, confectionery, dairy products, and baked goods to improve taste and extend shelf life |
| Pharmaceutical Industry | Pharmaceutical excipient (buffer, stabilizer); flavoring agent for oral liquids and tablets | Used as a buffering component during formulation to adjust solution pH, or co-blended with active pharmaceutical ingredients for granulation and tablet compression |
| Cosmetics Industry | Skin-conditioning agent, pH regulator | Added to aqueous formulations such as lotions and serums to maintain product stability and skin-physiological pH (4.5–6.0) |
| Animal Feed Industry | Organic acid-based feed additive for improving animal intestinal health | Blended with other organic acids (e.g., citric acid) and incorporated into compound feed as a premix |
Manufacturing Quality Control of DL-Malic acid disodium salt
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (DL-Malic Acid Sodium) | Acid-Base Titration | Quantifies sodium malate content by titration with standardized HCl using phenolphthalein or potentiometric endpoint detection. |
| Loss on Drying | Gravimetric Method (Oven Drying) | Measures volatile matter loss by weight difference before and after drying at 105 C for 2 h. |
| pH (1% aqueous solution) | pH Meter Measurement | Determines hydrogen ion activity in a 1% w/v aqueous solution using calibrated pH electrode. |
| Heavy Metals (as Pb) | Colorimetric Method (Thiourea/Na2S) | Compares color intensity of sample reaction with lead standard after sulfide precipitation under controlled pH. |
| Chloride | Argentometric Titration (Mohr Method) | Titrates chloride ions with standardized AgNO3 using K2CrO4 indicator to detect endpoint via red Ag2CrO4 formation. |
| Sulfate | Barium Sulfate Gravimetric Method | Precipitates sulfate as BaSO4, filters, dries, and weighs to determine sulfate content. |
| Iron (Fe) | Atomic Absorption Spectroscopy (AAS) | Measures Fe concentration by quantifying absorption of characteristic wavelength light by ground-state Fe atoms in flame. |
| Arsenic (As) | Hydride Generation AAS (HG-AAS) | Converts arsenic to arsine gas, which is swept into quartz cell for atomic absorption measurement. |
| Residue on Ignition | Gravimetric Method (Muffle Furnace) | Determines inorganic ash content by weight difference before and after ignition at 600 C for 1 h. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light by chiral DL-malic acid sodium in solution at specified concentration and path length. |
| Water Content (Karl Fischer) | Coulometric Karl Fischer Titration | Quantifies water via electrochemical generation of iodine reacting stoichiometrically with water in anhydrous methanol medium. |
| Microbial Limits | Membrane Filtration / Plate Count | Detects and enumerates aerobic microorganisms using filtration followed by incubation on nutrient agar plates. |
