Industrial Applications of Choline bitartrate
| Industry | Application | Processing |
|---|---|---|
| Pharmaceuticals | Used as a choline supplement to treat choline deficiency and fatty liver disease; serves as a pharmaceutical intermediate in the synthesis of phosphatidylcholine and other nutritional supplements | Formulated into oral dosage forms (tablets, capsules, solutions); co-crystallized or compatibilized with active pharmaceutical ingredients for stabilization |
| Food | Used as a food nutrient fortificant (choline source) in infant formula, functional beverages, and dietary supplements | Incorporated during the final stage of food processing (e.g., prior to spray drying) to prevent thermal degradation; complies with GB 14880-2012 “National Food Safety Standard – Usage Standard for Food Nutrient Fortificants” |
| Animal Feed | Used as a feed additive to supply bioavailable choline, preventing fatty liver syndrome in poultry and supporting growth and development in young livestock | Uniformly blended with premixes before incorporation into complete feed; recommended inclusion level: 200–800 mg/kg (as choline) |
Manufacturing Quality Control of Choline bitartrate
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification Test | Infrared Spectroscopy (IR) | Scan the sample and reference standard under the same conditions, compare characteristic absorption peaks to confirm molecular structure consistency. |
| High-Performance Liquid Chromatography (HPLC) | Confirm the identity of the main component by comparing retention time with the reference substance, used for authenticity verification. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reverse-phase column (e.g., C18), UV or evaporative light scattering detector, and external standard method for quantitative determination of the main component content. |
| Non-aqueous Titration | Determine the basic groups in tartaric acid choline using perchloric acid standard solution in a non-aqueous solvent (e.g., acetic acid), calculate the content accordingly. | |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Check for degradation products, synthetic intermediates, and other organic impurities by evaluating the resolution between the main peak and impurity peaks and their response values for limit control. |
| Moisture | Karl Fischer Titration | Quantitatively determine bound and free water in the sample using the iodine-sulfur dioxide reaction, suitable for trace moisture detection. |
| Dried Substance Loss | Thermogravimetric Analysis (TGA) or Oven Method | Determine the percentage of mass loss after heating at a specified temperature for a certain period, reflecting the content of volatile substances. |
| Residue on Ignition (Ash Content) | Sulfate Ashing Method | Determine the weight of inorganic residue remaining after high-temperature incineration of the sample, used to assess the level of inorganic impurities. |
| Heavy Metals | Atomic Absorption Spectrometry (AAS) or ICP-MS | Determine the content of heavy metals such as lead, cadmium, mercury, and arsenic after sample digestion, ensuring compliance with pharmacopoeia safety limits. |
| pH Value | pH Meter Measurement Method | Measure the acidity or alkalinity of the sample solution prepared at a certain concentration using a calibrated pH meter. |
| Clarity and Color of Solution | Visual Colorimetry or Spectrophotometry | Observe whether the test solution is clear and colorless, or compare it with standard color solutions to control visible foreign matter and abnormal color. |
| Microbial Limit | Microbial Limit Test | Determine the total aerobic bacterial count, mold and yeast count, and controlled organisms (e.g., Escherichia coli) according to the Chinese Pharmacopoeia or relevant standards. |
