CHAPTER ONE
INTRODUCTION
Beer is an alcoholic beverage obtained from fermented cereals such as barky, sorghum and maize grains. Barkey is a well know cereals for beer production due to some great advantage it has over other cereals but because of economic reasons other cereals like sorghum as many also in use for production.
The effect of major adjust in sorghum grain in beer production during which many is used a adduct to increase the carbohydrate content this carbohydrate is hydrolyzed to usable simple sugar during mashing which is later formatted by yeast (saacharonyces cerevisian) to production beer these are various type of alcoholic beverage some of which are as follows ales British beer and ates are described in many different ways in trade by this public some of the also are of wild bitter hight pale and scorch.
ii. stout. This is heavier type of beer in which well orated bardy or Walt or caramelized sugar is used Oatmed type stout is another special type main by the addition of a proportion of ostmed.
Lager beer: The main difference between also stomata companies with layer is the formation process. In that for ales and stout compared with lager is the fermentation processed. In that for ales and stout the yeast used is sarcharomyces cereisice and to formations is involved while sacharomyes carlsbergensis is used in lager and bottom fermentation is involved and lager beers more highly hopped than also and stout. Further the marshy force of ales and stout is carried out by an infusion process where as for larger a decoction process is used iv porter beer this is a weaker form of the stout now mainly brewed in treland it is saw to have derived it name from the fount that it was a popular drink of porter but in England the ordinary mild also have large superseded it . in beer production four technological processes we involved. They are as follow: malting mashing boiling wort and formation. Malting is the controlled germination process concerned with the modification of the grains that is the liberation of starch granle from the of endosperm cell and subsequent biosynthesis and digression of starch and protein by enzyme which wh9ich become activate during germination Aisen (1980) Malting loses of nutrient are encountered during steeping and respiration of the grains. In modern malting practices malting loses are highly controlled due to the use of
