(Some Chemist)   Aspartame decomposes to diketopiperazone, which is why aged diet soda tastes like the fluids expelled by an asparagus-eating keto dieter, and why this is on the Food tab instead of the STEM tab   (foodscienceinstitute.com) divider line

oh subby, don't you know I'm only drinking bespoke soft drinks made with free range aspartame, served in a cruelty-free vessel made of tree bark?

I remember grabbing a 20oz bottle of Pepsi Zero at a discount grocery store. Unfortunately I didn't realize that the bottle was expired and it tasted like pencil shaving.

Phenylalanine is sold as an OTC supplement. It affects serotonin levels and is not a complete quackery antidepressant. The 'L' form is listed as 'bitter'. I'm assuming the aspartame doesn't stay in the intermediate form.

Sucralose has a similar story with its discovery. A food and beverage research company was doing research on synthetic sucrose derivatives and one of the researchers was asked to "test" a new chlorinated sucrose compound. The researcher, Shashikant Phadnis, misheard him and thought he said "taste" and tried some. He found that it was extremely sweet and safe. And that's how we got sucralose.

Supposedly this one can take the edge off hangovers.

Back when aspartame was first introduced, I went to a convention in Phoenix, AZ, in the summer.  The soda had been stored in an unconditioned warehouse.  Bad.

I don't use aspartame any more, when I was younger it would mess with me, make me feel overly euphoric where I couldn't stop laughing and sometimes would black out. No idea why and it would happen if I didn't know what I was drinking, caffeinated and non-caffeinated beverages.

Could have been psychosomatic, but to be on the safe side I have touched the stuff in 30 years.

I try to avoid foods with artificial sweeteners as they never seem to taste right. They're sweet, but it's at a level that feels nauseous. Plus they leave an aftertaste that's difficult to get rid of. It's either a cloying sweetness or something vaguely bitter and metallic.

My body can handle aspartame, it's the HCFS that nauseates me.

Artificial sweeteners give me the hiccups. Like, after one swallow. Wife always orders diet coke when we eat out, and if they mix our drinks up, I find out the hard way in minutes. Trying to eat in a restaurant, while having hiccups, is nearly impossible, in addition to embarrassing. I just ask for water, now.

If you unzip aspartame into the two amino acids and remove that methyl to become methanol, you have a tasteless mixture of pretty harmless compounds. Your body easily metabolizes that bit of methyl alcohol and you are none the worse for it.

Methanol? Aspartame metabolizes into methanol? Antifreeze methanol? Poisonous antifreeze methanol? None the worse? They just SKIPPED right past that bad boy. Let me Google methanol toxicity ...

Methanol is not toxic itself, but it is metabolized to become highly toxic formic acid and its anion formate. Formic acid can create a metabolic acidosis, and both formic acid and formate inhibit the respiration chain in the mitochondria of the cells in the human body.


Ha! So your body will indeed easily metabolize methanol (they are technically correct), but it's metabolites are cyanide-like poisons. It doesn't sound like a good thing to drink in large quantities, expired or not.

/Well, I drink ethanol in large quantities and that's an easily metabolized poison, so I guess I'm a hypocrite
//But methanol!

The dose makes the poison. It's very dilute. You aren't gonna have a problem with concentrations in food.

Methanol is a natural byproduct of fermentation. It dissipates from foods. Nothing is done to remove the scant quantity in beer/wine. It is a cohort to hangovers. It's concentrated in liquors and the amount is dependent on the quality of distillation.

Yes, I kept reading about methanol thoughout the day.  I can't find the link now (different puter) but approx 30mg of methanol is produced naturally in our body and is used to regulate some processes, so it's not all bad.

"Don't drink expired diet sodas." Got it, thanks.
