Coca-Cola is made from a syrup produced by the Coca-Cola Company of Atlanta. The main ingredient in the formula used in the United States is a type of sugar substitute called high-fructose corn syrup 55, so named because it is 55 per cent fructose or “fruit sugar”, and 42 per cent glucose or “simple sugar” — the same ratio of fructose to glucose as natural honey. HFCS is made by grinding wet corn until it becomes cornstarch. The cornstarch is mixed with an enzyme secreted by a rod-shaped bacterium called Bacillus and an enzyme secreted by a mold called Aspergillus. This process creates the glucose. A third enzyme, also derived from bacteria, is then used to turn some of the glucose into fructose.
