I figured that out in Year 9. The moment I did, I gave it up for good. It's amazing how many people refuse to believe Coke contains that.
For number referencing, phosphoric acid is 338. The common 330 food acid is citric acid, which is apparently carcinogenic if overconsumed. Problem is, it's used as a preservative in almost anything.
