| titleOfInvention | A kind of preparation method of zinc histidine |
| abstract | The invention provides a preparation method of zinc histidine, which belongs to the technical field of compound preparation. The preparation method of zinc histidine provided by the present invention comprises the following steps: mixing L-histidine and a zinc source with water, and performing a chelating reaction to obtain a chelated product system; wherein, the zinc source is zinc oxide or Zinc hydroxide; the chelated product system is concentrated and then crystallized by cooling to obtain zinc histidine. In the present invention, zinc oxide or zinc hydroxide is used as the zinc source, no alkaline reagent is needed to adjust the pH value of the system, and L-histidine, zinc source and water are directly mixed, and the zinc histidine can be prepared by a one-step method, The introduction of nitrate or sulfate which is harmful to the body is avoided, the process is simple, and the cost is saved; at the same time, in the present invention, the target product zinc histidine is precipitated in the form of crystals, and the product has high purity, good quality, safety and non-toxicity, and is a later stage. Provides protection as a feed additive. |
