Production of fermented alcoholic products having a low diacetyl content

摘要

Fermented alcoholic products such as wine and beer are produced having a low diacetyl content by decomposing acetolactate with an enzyme. The enzyme is preferably acetolactate decarboxylase contained by Aerobacter aerogenes. The enzyme, in free or immobilized state, may be added during main fermentation or after main fermentation during maturation such as when carrying out malo-lactic fermentation.
