Abstract: Eight
different sorts of malt beverages were collected from the local markets of
western province of Saudi Arabia. The studied samples were subjected to the
determination of physicochemical Characteristics such as pH, conductivity and
TDS. Also, the concentration of 15 major and trace elements has been determined
using inductively coupled plasma-atomic emission spectrometry. The levels of
all investigated elements were below the maximum tolerance levels reported by
international regulatory standard. The beverages were tested quantitatively by
capillary gas chromatography for their alcohol content through three steps.
Firstly, the studied samples were directly analyzed, secondary, the samples
were analyzed after exposing to air and finally the samples were analyzed in
presence of yeast. It has been found that there is no ethanol content
when the samples analyzed directly, minor concentration of ethanol content was
found after exposing malt beverages to air ranging from 12.7 ppm in Hillsgurg
to 1940.6 ppm in Efes. Considerable variability in the alcoholic strength was
found in presence of yeast due to fermentation, overall, the range of
concentrations was 0.4621 Vol % in Budwisers to 3.416 Vol % in Hillsgurg.
