Do you know long the coffee cans are kept heated? I'm concerned that those cans have had hot coffee in them for days on end, which is generally not good for food (heat breaks down its nutrients and often produces free radical byproducts).

- Cthulhu_ 9y agoNeat. I have / used to have a pair of 'hand warmers', plastic bags with a fluid of sorts and a copper (?) coin you can 'flip over', the click / shock causing the fluid to crystallise and generate heat. Those can be reused too by putting the (crystallised) bag into hot water for a bit.
- CryptoPunk 9y agoAre the heated cans sold in the Japanese vending machines self-heating cans? EDIT: According to this, the Japanese ones keep the cans heated: http://www.vendingmarketwatch.com/article/10273776/hot-can-vending-initiatives-emerge-in-the-us http://www.vendingmarketwatch.com/article/10273776/hot-can-v... >>Proprietary heating technology >>Unlike hot can drink machines in Japan, the Starbucks machine does not keep the steel cans heated. Instead, the container heats after the customer makes a selection.
- jdale27 9y agoNot sure in general, but I'm pretty sure I have encountered the self-heating kind in Japan.
