DESATASE is an amylolytic preparation (EC 3.2.1.41, pullulan 6-glucano-hydrolase) which catalyzes the hydrolysis of the alpha-1,6 linkages of amylopectine allowing to reach higher maltose yields in combination with maltogenic amylases. PURPOSES To increase the malt diastasic power by enhancing the malt native ß-amylase action. To increase the fermentability of wort (apparent attenuation limit). Some 25% of the total carbohydrate of wort is unfermentable. The addition of Desatase in combination with maltogenic amylases like Maltosylase to the fermenter converts the unfermentable dextrins to maltose which in turn is fermented to alcohol giving an apparent attenuation higher than 100% without loss of palate fullness or head retention. At the same alcohol concentration as a normal attenuated beer the super-attenuated beer will have required 25% less of raw material. See Attenuation Modulation. TEMPERATURE Optimum 55-60°C. The enzymatic components are deactivated in beer (pH 4,2)...

GUMINASE is a mixture of fungal carbohydrases including ß-glucanases (ß1-3 and ß1-4 endo-glucanases) xylanases and hemicellulases. This well balanced mixture of carbohydrases is free of proteases to avoid the increase of wort coloration and to preserve the beer pro-foam proteins. TEMPERATURE GUMINASE can be used to 75°C and is quickly inactivated above this temperature. The usual temperatures used during mashing coincide with GUMINASE’s optimum activity. pH EFFECT Optimum pH between 4.5 and 6.5. PURPOSES To decrease the wort ß-glucan and pentosane content and the wort viscosity and to make easier the mash filtration as well as the beer filtration mainly when brewing with high levels of raw grains as barley or wheat. EXAMPLES Effects of the addition of GUMINASE to a sample of GATINAIS malt and to a mixture of 75% malt and 25% raw wheat (EBC conventional mash). A = addition of 1 kg per 10 tons of malt B = addition of 3 kg per 10 tons of malt C = addition of 1 kg per 1 ton of raw...
