can be produced industrially is to culture enzymes in vats.Man has been exploiting enzymes in nature unknowingly for centuries. Also for thousands of years the beer brewing processes of many countries has relied heavily on barley malt. In this period of time barley was malted without brewers understanding what happen to the barley during the malting process. The idea back then was good beer couldn’t be made without malted barley. The unknown fact of that time was that the most important difference between raw barley and malted barley was the enzymes present in the malted barleyEnzymes in malt can be produced industrially, in some cases the industrially created enzymes are an improvement of the malt’s enzymes. Better in the sense that they are better conditioned or adapted to the conditions found in brewing. The quality of malt and also its enzymes content can vary. Industrial enzymes can allow the brewer’s batch to make up for malt’s deficiency or it can replace a quantity of the malt with cheaper raw material such a raw barley to cut down on costs. Beer production is a sequence of chemical engineering “ unit operations” the processes of brewing beer are as follows milling, boiling, fermentation and filtration/extraction. There are three steps in beer brewing: (1) preparation of the wort or liquid extract of the malt, (2) the conversion of this liquid extract which is called fermentation, (3) refining of fermented beer into salable/drinking beer.The process of brewing beer, is show in the plant design below which shows the sequence of action as the barley makes its way though the different stages to become a finished product which is great tasting beer.The design of plant below shows the process and the description of the enzymes in that process:The Brewing ProcessMalted Barley, malting (enzyme: cytase, amylase, catalase) Hot water (preteol...
