The extraction, separation and purification process of fermented erythritol is a complex process involving multiple steps, which can be summarized into the following key stages: 

Preparation of the fermentation broth; 

Fermentation process 

Separation and extraction; 

Purification process 

Drying and packaging. 

During the entire process of extraction, separation and purification, the following points should be noted: 

The selection of the bacterial strain and the control of fermentation conditions have a significant impact on the yield and purity of erythritol. 

The selection of separation and purification techniques needs to be comprehensively considered based on the actual situation, in order to ensure that the yield and purity of erythritol meet the market demand. 

The entire process requires strict control over the quality and efficiency of each stage to ensure the quality and safety of the final product.
