Natunase ALDC is a purified alpha-acetolactate decarboxylase enzyme derived from Bacillus licheniformis. Acetolactate decarboxylase (ALDC) has the unique ability to decarboxylate both enantiomers of acetolactate to give a single enantiomer of the decarboxylation product, (R)-acetoin. This enzyme has application in brewing industry. Natunase ALDC meets requirements for food grade enzymes as designated by JECFA/FCC. Local food regulations should always be consulted with respect to specific applications and necessary declarations.

  • Natunase ALDC is used in the fermentation of beer
  • It converts acetolactate in beer into acetoin, bypassing the formation of diacetyl. Diacetyl has a very low off-flavor threshold
  • Treatment with Natunase ALDC significantly reduces the maturation period
  • Natunase ALDC is to be added to the cold wort at the beginning of fermentation. It can also be added just after filtration & before canned in order to eliminate the rebound of the diacetyl during beer storage.


A 15 days curing process is required during the brewing of beer to ensure that yeast has time to absorb diacetyl, produced during conventional brewing-otherwise the beer has a characteristic ‘off’ odour and taste, rendering it undrinkable. Acetolactate decarboxylase (ALDC) allows brewers to bypass the reaction that produces diacetyl by catalysing non-oxidative decarboxylation.
