Aluminium content of soft drinks from aluminium cans

Abstract

The aluminium (Al) content of soft drinks from Al cans has been measured during 12 months of storage, by the graphite furnace atomic absorption spectrophotometry (GFAAS) method. The results show that the Al content in all soft drinks increased during the whole storage time. This increase was a result of dissolution of Al from the can wall due to the presence of aggressive ingredients in the soft drinks, mainly acids. The Al content rose with increasing acid concentration and decreasing pH value of the soft drinks. The evaluated possible daily intake of Al (0.8 mg) through consumption of these drinks was practically negligible in relation to total daily dietary Al intake, as well as to tolerable daily intake. Thus, soft drinks from Al cans are an insignificant source of dietary Al intake and it appears that the Al intake from this source should not be a cause for concern in regard to Al toxicity for the human body.

Aluminium content in beers and silicon sequestering effects

“…with an increase in the content of total acids. The corrosion rates are much higher in the cola-based drinks than those in citrate-based drinks, due to these facts: (1) orthophosphoric acid is more corrosive to aluminium than citric acid is; (2) a quite different passive oxide layer (with different properties) is formed on Al, depending on whether the drink is cola or citrate based (Seruga, Grgić, & Mandić, 1994;Seruga & Hasenay, 1996).…”

Aluminium content of some processed foods, raw materials and food additives in China by inductively coupled plasma–mass spectrometry

“…Some processed foods contained high levels of Al, which could come from processing, packaging material, cookware, drinking water, food additives or the raw material (Greger et al 1985;Pennington 1988; Martin 1992;Fairweather-Tait et al 1994;Seruga et al 1994;Pennington and Schoen 1995;Muller et al 1998;Soni et al 2001). The raw materials could be polluted by soil, water and air contaminated with aluminium.…”

“…Food is the main source of aluminium intake because unprocessed food could be polluted by soil, water and air contaminated with aluminium. Al in processed food might also come from processing, packaging material, additives or cookware (FDA/WHO 1989;Fairweather-Tait et al 1994;Seruga et al 1994;Pennington and Schoen 1995;Muller et al 1998). Therefore, it is necessary to monitor the content of Al in food.…”

Health-Related Aspects of Beer: A Review

“…If the aluminum alloy of high quality is not used during the production of the containers, migration of aluminum to the product will accelerate. [179] There is a possible direct relation between high aluminum content in the tissues and neurodegenerative disorders (such as Alzheimer's disease) or other encephalopathies or in some cases osteomalacia is present.
