| description | The invention relates to a refining method for D-potassium isoascorbiate, and belongs to the technical fields of preparation and purification of the D-potassium isoascorbiate. The refining method forthe D-potassium isoascorbiate includes the following steps: taking a reaction liquid of the D-potassium isoascorbiate, performing separation to obtain crude D-potassium isoascorbiate, dissolving the crude D-potassium isoascorbiate, adding a decolorizing agent, performing decolorization, removing the decolorizing agent to obtain a decolorized D-potassium isoascorbiate dissolved solution, after thedecolorizing agent is removed, adding a complexing agent, performing complexing to obtain a complexed D-potassium isoascorbiate dissolved solution, performing crystallization, performing washing and performing drying to obtain the D-potassium isoascorbiate. The refining method for the D-potassium isoascorbiate purifies current D-potassium isoascorbiate synthesized by using calcium 2-keto-D-gluconate obtained by fermentatio |
