  • If I understand your question correctly, the only thing I'm aware of us is to keep it out of direct heat and freezing temps.
  • Yes "The level of aspartame in a can of Diet Coke was found to be 0.06% by a food testing laboratory. The remaining cans from one case of Diet coke were stored under three different heat conditions for 10 weeks. Seven cans were stored in an incubator (104 degrees Fahrenheit), seven cans were stored at room temperature (68-70 degrees Fahrenheit). At the end of 70 days samples were tested for levels of aspartame, formaldehyde and DKP (diketopiperazine). The refrigerated sample contained 0.058 percent aspartame, 0.001 percent DKP and 53.5 parts per billion of formaldehyde. The room temperature sample contained 0.051 percent aspartame, 0.002 percent DKP and 231 parts per billion of formaldehyde. The incubator sample contained 0.026 percent aspartame, 0.010 percent DKP and 76.2 parts per billion of formaldehyde. In addition 10 human subjects tasted each soda sample plus a new can of Diet Coke and rated each sample for taste on a 1-4 scale with 1 being the best and 4 being the worst. The new can of Diet Coke received an average rating of 2.0. The sample stored in the refrigerator received an average rating of 2.6. The sample stored at room temperature received an average rating of 2.5. The sample stored in the incubator received an average rating of 3.8. The effects of heat on Diet coke produced the worst taste and the highest amount of loss of aspartame as well as the greatest increase in levels of DKP. The most pleasing taste was for the new can of Diet Coke. The room temperature sample and the refrigerated sample scored almost the same in the taste test. All samples revealed a presence of formaldehyde. However, the highest level of formaldehyde occurred in the room temperature can. There was also formaldehyde present in the refrigerated sample."
