Process for the production of non-alcoholic beer and device for effecting this process.

摘要

The invention relates to a process for the production of non-alcoholic beer, the pH-value of the wort being adjusted in that wort is fed through a bioreactor with lactic acid producing bacteria immobilized on a specific carrier, the acidified wort flowing out of the bioreactor being allowed to reside in a post-treatment container and subsequently being mixed with a non-acidified wort which is to be adjusted to a specific pH-value. A preferred embodiment of the carrier includes microfibres or microparticles of diethyl-aminoethylene-substituted cellulose (DEAE-cellulose), which are bonded and agglomerated to one another by polystyrene. The invention also includes an apparatus for effecting this process. The large-scale acidification of wort by means of immobilized lactic acid producing bacteria is made possible by means of this process.
