    Soft drinks sweetened with Aspartame definitely "go bad" in not too long a time, perhaps 6 months, depending I suppose on temperature prevailing during storage. The "sweet" taste degrades, becoming first noticeably less sweet, then gradually downright distasteful. Whether at that point this is due to "bad" Aspartame taste, or just lack of sweetness perceived, I cannot say.

    Just wondering in view of all the hoopla about Aspartame and the human body, whether degraded Aspartame in outdated soda is dangerous to consume. Which brings up another thought: does Aspartame packaged for use as a sweetener degrade when stored unmixed with any other material? jocular

    Considering you didnt show that the taste change was due to the aspertame or some other effect, if present, there is no way to comment on your question.

    Conventional wisdom says that aspartame does break down, especially in heat and light.
    Personally I avoid it altogether.

    Make sure you expand the "Safety and Handling" part of the next link. I think it has what you are after.

    True that it does, however it specifies that it take heat or high ph to cause this, otherwise its stable.

    the study you link to is from 1987, and in the intervening 26ish years it has still been shown to be safe.

    Oop, yeah, never mind the study from 87'. Regardless, I still don't want to consume any.
    However, from the last link;
    In the dark, 91% of aspartame in an aqueous solution at pH 7 remained after 10 h of storage. Under 5500 lux of light, however, 39% of aspartame in the solution was destroyed after 10 h of storage.
    7 is a neutral pH.

    Many/Most drinks are not ph neutral though, and as noted in the facts sheet, a number of complimentary chemicals are used to stabilize the Aspartame longer.

    May i ask why you avoid it?

    Then, what is the point of commenting in this way (above)? To discredit me? This, of course, makes you look all the more believable, non? Why not use superior intellect instead to answer the question posed about degradation of Aspartame? jocular

    Few chemicals are actually complimenting one another. Did you mean complementing? jocular

    Why, and HOW, could I show what caused the taste change? I asked a question, based on an observation (taste change). YOU have twisted and manipulated that question to imply I should have provided additional information. If that were the case, I would not have needed to ask anything at all, in the first place, yes? Now, YOU are in the limelight. Enjoy. jocular

    Hmmm, someone was in a foul mood.

    I was pointing out that given the amount of data given, there wasnt much that could be commented on.

    I think we might be using slightly different assumptions of high/low pH. I'm assuming 7 is neutral, consequently <7 is low and >7 is high.

    My dietary habits are such that I simply don't encounter aspartame very much or really ever. And there is the hoopla, better safe than sorry. Avoiding aspartame doesn't have the consequences of say, avoiding vaccination.

    And to be fair to jocular, his OP did specify that he was uncertain as to aspartame degradation being the specific cause of flavor change.

    Good point!

    I simply know that non-aspartame containing soft drinks do not experience anywhere near as drastic a taste change, even over much longer periods of time. I did not think this issue worthy of getting into a "pissing-match" over. joc

    Welcome to science.
    Thank you for putting it as tenderly as this. I have indeed experienced a rash of bouts of foul mood lately, and should refrain from allowing them to be invasive here. For that, I apologize, FWIW, at this point in time. Your indulgence is appreciated! jocular
