Maturex L

Brewing / 2001-00485-03.pdf Product Sheet Page 1:5 Maturex L Description Maturex L is a purified alpha-acetolactate decarboxylase (ALDC) from Bacillus brevis produced by a genetically modified strain of Bacillus subtilis. ® Product Properties Product type The product is a brown liquid with a density of approx. 1.2 g/ml. Activity Maturex L is available with 1500 ADU/g. One alpha-Acetolactate Decarboxylase Unit (ADU) is the amount of enzyme which, under standard conditions, by decarboxylation of alpha -acetolactate produces 1 µmol of acetoin per minute. See the Analytical Method for further information. Food-grade status Maturex L complies with the recommended purity specifications for food-grade enzymes given by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the Food Chemicals Codex (FCC), supplemented with maximum limits of 5 x 104/g for total viable count and 102/g for moulds. Packaging See the standard Packaging List for more packaging information. Application Maturex L is used in the fermentation of beer. As shown in Figure 1, it prevents the formation of diacetyl by catalyzing the decarboxylation of alphaacetolactate to acetoin. Thereby the maturation period can be eliminated or greatly reduced.
