dc.description.abstractThe analysis of some Beers such as Star and Guider from Nigerian Breweries Limited, Kaduna; Bock, Jos International Breweries Limited, Jos; Double Crown, North Brewery Limited, Kano; Stout, Nigerian Guiness Stout Limited, Lagos, and Noble, Kwara Breweries Limited, Ijagbo, has been carried out to determine the quality of various Beer samples. The exercise includes• (l) estimation of alcohol by volume and by weight or mass, apparent extract, real extract and specific gravity; (ii) determination of the nutritive value of beer, determined by estimating the total nitrogen (protein, reducing sugars and dextrine; (iii) determination of the chemical compositions of the beers by estimating the ash; (iv) determination of carbon dioxide content, colour, total acidity, volatile acidity and fixed acidity in the beers. These constitute the organoleptic property of beers (v) study of stability of the beers. This involves the estimation of apparent attenuation, real attenuation and determination of pH and Haze or turbidity of the bottled beer. (vi) Last study is concerned with some factors which affect the quality of bottled beer. This requires the determination of 2. the concentration of copper, iron, and chloride ions present in the beer samples. The quality of various samples of beer based on the analytical study suggests that deterioration in shelf-life of beers solely depends on the quantity of iron, copper or chloride ions present. Iron and copper have catalysing effects on the quality of beer since their presence introduces oxidationreduction processes to occur, while the presence of chloride ion in high concentration may lead to deterioration in the beer taste.en_US
