Brewing is a process involving conversion of starch in to simple sugars for further conversion in alcohol and carbon dioxide. Brewing has always been an enzymatically driven process. Endogenous enzymes in the malted barley convert starch to fermentable sugars which are utilized to produce alcohol. Enzymes are added to improve this starch conversion in some barley malts.
A high NSP containing cereals like unmalted barley, wheat rye, etc., when used in the beverage industry creates problem of high viscosity in the mash that leads to slow filtration rate and more rejections. To overcome the problem of such adjuncts containing high NSPs Lumis Biotech offers enzyme complexes of Xylanase, Cellulase and Glucanase or tailor made enzyme for breakdown of these cellulosic materials aiding to reduce the viscosity for higher extraction yields. In addition to above we also provide protease enzyme used for hydrolysis of protein (neutral protease) to increase the (later) fermentation rate, particularly in the production of high-gravity beer, where extra protein is added. Papain is used in the later post-fermentation stages of beer-making to prevent the occurrence of protein- and tannin-containing ?chill-haze?otherwise formed on cooling the beer.
