ABV ALPHA ACETOLACTATE DECARBOXYLASE

ABV Alpha Acetolactate Decarboxylase is a decarboxylase enzyme which prevents the formation of diacetyl by the decarboxylation of alpha-acetolactate to acetoin, and is derived from Bacillus lincheniformis

PHYSICAL FORM

ACTIVITY
min. 2000 Units/g

One a-ALDC unit is the amount of enzyme which at 30C, pH 6.0 produces one unit of acetoin per  minute by the decarboxylation of alpha-acetolactate.

TOTAL  VIABLE COUNT                     < 3000/g

YEAST &  MOLD                                    < 100/g

Reduces cold conditioning time.
Prevents formation of diacetyl.

A typical dosage is 10-15g/1000L (10-15ppm) is to be added to the cold wort at the beginning of fermentation.
