Alpha-Acetolactate Decarboxylase

Alpha-Acetolactate Decarboxylase (SBAD-008) is made from microorganism through liquid deep fermentation and extraction technique. It is yellowish liquid, designed specially for beer industry.

Action mechanism:

Diacetyl is one of the inevitable metabolic side-products during beer fermentation, it is the symbol of beer maturity. It is generally regarded that diacetyl is formed by the oxidation and decomposition of cetolactic acid, which is the intermediate product of synthesis from yeast to valine, leucine and isoleucine. If use this product during fermentation process, it can penetrate into yeast cell through cell wall and membrane to makeacetolactic acid convert to 3-hydroxy-2-butanone directly, and then convert to 2, 3-butanedione, so as to decrease the content of diacetyl and decomposeα-acetolactic acid thoroughly.


Avoid or decrease the form of diacetyl to ensure low content of diacetyl in beer, so as to ensure the beer flavour; Decrease the content ofetolactic acid in beer, eliminate or decrease the rebound extent of diacetyl, so as to ensure the stability of beer; Shorten or eliminate the reducing period of diacetyl, so as to decrease the content of higher alcohols and higher lipin generated due to high-temperature metabolism of yeast; Shorten fermentation period greatly, so as to improve the utilization of equipments and reduce production cost.
