Appendix 1 Abstract
This project is a survey of level of alcohol in beverages produced in Nigeria and to ascertain the compliance of the producers in accordance with accepted values on WHO recommendation. Six brands of alcoholic beverages (Guilders, star Harp, Heineken, Stout and Legend) were bought in Awka in Anambra state. The samples were analyzed for level of alcohol (Ethanol) using acid dichromate reaction and visible spectroscopy methods. The result obtained for bottom fermented beers; Guilders 5.1, star 5.3, Harp 5.2, Heineken 5.1, top fermented beer Stout 7.2 and Legend6.5 were compared with the European Brewing convention standard of 5.1+0.2 and 7.3+0.2 for bottom and top fermented beer respectively. The result showed , permissible levels for each of the six samples analyzed which are within acceptable limit except for legend stout with alcohol content of 6.5 against 7.3+ 0.2 which is the European Brewing convention standard for top fermented beer. The six samples are within the acceptable limit.
