answer:I’m having an amazing amount of trouble finding the answer to your question. I did find information on how much corn it takes to make corn syrup, which is not the same product, of course. It’s a completely different production method: When wet milled, about 2.3 litres of corn are required to yield an average of 947g of starch, to produce 1 kg of glucose or dextrose syrup. A bushel (25 kg) of corn will yield an average of 31.5 pounds (14.3 kg) of starch, which in turn will yield about 33.3 pounds (15.1 kg) of syrup. Thus, it takes about 2,300 litres of corn to produce a tonne of glucose syrup, or 60 bushels (1524 kg) of corn to produce one short ton. Working backward from your Coke can ingredients, it might be possible to get a very rough idea of how much corn would be used if corn syrup were used. Since high fructose corn syrup contains more fructose, it is sweeter, but I have no idea if the production numbers of the two products are comparable.
