Aluminium gives beer a metallic and bitter flavour without any observations on particular aroma compound changes Besides it has lately been implicated as one of the possible causal factors contributing to Alzheimer s disease
A highly sensitive selective rapid reliable and inexpensive method has been used for direct analysis of free aluminium in thirty-nine samples of bottled lager beer Differential pulse adsorptive anodic stripping voltammetry (DPAdSV) technique at a hanging mercury drop electrode (HMDE) without any sample digestion was performed
Thirty nine different commercial beers (dark pale and alcohol-free) were analysed The aluminium content ranged between 3 and 15 ppb The results show that in non-Spanish beers the aluminium content in alcohol-free beers is lower than in dark and pale beers Nevertheless in the case of the national beers -Spanish- no relation has been observed between the content of aluminium and the type of beer Since beer also contains silicon which can affec
