Improvement of electric process of lactic acid production

Abstract

Industrial technologies of lactic acid production from lactic whey are based on the processes of fermentation of lactose contained in it and separation of the final product in the form of lactates. The necessity of neutralization of the forming lactic acid in medium being fermented as well as the following crystallization of lactates with the recurring dissolving and release of the acid makes this technology power–consuming and long. Working out the direction, combining fermentation of the lactic whey and electrophoretic removing of the formed acid, ensuring a high degree of lactose utilization and pure lactic acid production, seems to be expedient. However application of electrodialysis process has it own limits, caused by the presence in the medium of the substances (proteins, mineral salts), inhibiting the membranes.
