Alpha-Acetolactate Decarboxylase for diacetyl reduction

 PRODUCT DESCRIPTION

Alpha-Acetolactate Decarboxylase is produced by submerged fermentation of Bacillus subtilis followed by purification and formulation. It is widely used in food processing. 

MECHANISM

Diacetyl, the α-acetolactate oxidative decomposition product, is an intermediate along the synthesis of amino acids in yeast, especially of valine and isoleucine. This decomposition process is very slow in yeast. Alpha-Acetolactate Decarboxylase can speed up the transformation of α-acetolactate into acetoin efficiently, avoiding the formation of the diketone, an off flavor in beer, and thereby greatly reducing diacetyl level in beer and diacetyl reduction time. In this way beer maturation time is saved.

REACTION PARAMETERS

PRODUCT SPECIFICATION

Light yellow liquid. Color may vary from batch to batch. Color intensity is not an indication of enzyme activity.

PRODUCT STANDARD

The product complies with GB1886.174.

APPLICATION RECOMMENDATION

The recommended dosage is 5-500g/t DS. The dosage has to be optimized based on each application, the raw material specifications, product expectation and processing parameters. It is better to begin the test with the convenient volume.

SAFE HANDLING PRECAUTIONS

Enzyme preparations are proteins that may induce sensitization and cause allergic type of symptoms in susceptible individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa. Any direct contact with human body should be avoided. If irritation or allergic response for skin or eyes develops, please consult a doctor.
