Do drinks from aluminum cans contain aluminum?

Many acidic softdrinks are sold in aluminum cans, 
dont these drinks contain some residue of aluminum ?

Soft drink cans are coated with a very thin layer of BPA, which you can see for yourself by dissolving the can from the outside in concentrated sodium hydroxide. In analytical chemistry, we attempted to quantify aluminum in the liquid using a complexing agent and a spectrofluorometer (I don't remember the name of the complexing agent anymore). Our results were non-detectable.
