$Coke Just Revolutionized Coke Our last video about Mexican Coke made a bold claim: that Mexican Coke has no (unhydrolyzed) sugar in it. Two chemistry professors called us on that claim, so George visited them to run definitive tests on their expensive instruments… and he accidentally discovered that Coke is doing something they haven’t told ANYONE about. And that raised some questions that only @planetmoney could answer. #cocacola #sugar #chemistry CLARIFICATION: In the video I said that Coke hasn’t done this before, but they have, of course, put cane sugar in sodas before. What they haven’t done – at least to my knowledge – is deliver a soda to our hands that has an appreciable amount of unhydrolyzed cane sugar in it.
