How do you get Alginic Acid or E400?

The E400 additive is obtained through a bacterial fermentation process using the bacteria called xanthomonas campestris. Below, I detail the general steps of the process

Cultivation of bacteria It begins by creating a culture of the bacteria xanthomonas campestris in a suitable culture medium that contains the nutrients necessary for its growth, such as glucose and other specific nutrients.

Fermentation Once the bacterial culture has reached an optimal concentration, fermentation takes place in large tanks called fermenters. During this process, bacteria produce a slimy substance called xanthan, which is the additive E400.

Extraction and purification Once the fermentation is completed, the xanthan is extracted from the bacterial solution through physical and chemical processes. This includes the separation of bacteria and the removal of impurities and unwanted by-products.

Drying After extraction, the xanthan is dried to obtain a fine powder which is the additive E400. This process can be carried out using different methods, such as evaporation, vacuum drying or spray drying. It is important to note that this is just a general process and the specific details may vary by manufacturer. In addition, it is advisable to consult the corresponding legislation of each country, as there may be specific regulations on the production and use of food additives.
