| titleOfInvention | Preparation method of superfine calcium citrate |
| abstract | The invention relates to the field of biochemical engineering, and in particular relates to a preparation method of superfine calcium citrate. The method comprises the steps of mixing a sodium source and a citric acid solution according to a certain molar ratio to react to obtain a clarified liquid of citrate, adding inorganic calcium source slurry into the clarified liquid to react to generate a calcium citrate solid, then carrying out solid-liquid separation, washing and drying to obtain the superfine calcium citrate. The method can directly prepare the superfine calcium citrate, the particle size of the superfine calcium citrate is uniform, the corresponding particle size is not more than 13 microns when the cumulative particle size distribution number of a sample detected by a particle size analyzer reaches 90 percent, the quality is high, the preparation process is simple and easy to operate, and no pollution is caused. |
