Description

α-Acetolactate Decarboxylase is a highly specific enzyme that catalyzes the decarboxylation of α-acetolactate to acetoin. This reaction is critical for controlling diacetyl levels, a key off-flavor compound, in fermented products. It is an essential processing aid for breweries and distilleries seeking to ensure consistent flavor profiles and accelerate maturation times. Industrial bioprocesses also utilize this enzyme for the efficient production of chiral intermediates.

Application

• Beer Production (Diacetyl Control): Primary application for reducing maturation time by converting precursor α-acetolactate directly to acetoin, bypassing diacetyl formation.
• Wine & Cider Making: Used to manage diacetyl levels and stabilize flavor development during fermentation.
• Fuel Ethanol & Distilled Spirits: Enhances fermentation efficiency and helps control flavor congeners in alcohol production.
• Food Ingredient Fermentation: Employed in the production of various food-grade ingredients where diacetyl control is necessary.
• Biocatalysis & Chiral Synthesis: Serves as a catalyst in organic synthesis for the production of enantiomerically pure compounds.
• Animal Feed Additives: Potential use in silage fermentation to improve quality and preservation.
