Process for concentration of fermented juices by reversed osmosis

摘要

The present invention relates to a process for treating fermented juices by reversed osmosis in particular for increasing concentration thereof in organic substances. The fermented product is treated under a pressure of from 30 to 120 bars and a strong turbulency by passing it through at least one semi-permeable membrane having a high retention rate with respect to organic substances of molecular weights lower than 200.
