Regular coffee beans are extracted with a solvent that takes only the caffeine and a small number of the flavoring compounds.  In the old days they used methylene chloride, but nowadays they use supercritical carbon dioxide.

To separate caffeine, you could use HPLC, LC, GC, or TLC, which are all chromatography techniques. \n\nIf you do a physical separation, a polar organic solvent would do nicely.\n\nTo make sure that you are actually extracting the chloroform, suspend the separatory funnel on a ring off of a ring stand. Wait 10 mins. You'll see two layers, a top layer and bottom layer.\n\nChloroform has a density of 1.48 g/mL and water has a density of 1 g/mL, so the chloroform will be the bottom layer. Use the sep funnel to recover all the chloroform. At the end, I'd run saturated sodium chloride through the chloroform and separate that, to clear any nonorganics from the chloroform.\n\nAfter that, you can put the chloroform on a rotavap or do TLC to see if you have caffeine and caffeine only (doubtful)

Same here, first cup always THE best, and I'm picky about coffee....I drink Yuban Dark Roast, with over 30% Rain Forest beans...excellent flavor..\n\nAnd this is a morning ritual with me, put coffee on, start computer, check email accounts, read news, go to Yahoo! Answers...and play a few games... :)

You can purchase Wolfgang Puck coffee, in self-heating cans, at the grocery store.  (Albertson's, Vons, etc.).\n\nYou push a button in the bottom of the can and the coffee is hot in 6-8 minutes.  Keep a couple in your car or desk!

In general - I would recommend sticking with normal green tea as the amount of caffeine is so low that you have nothing to worry about.\n\nI would think that this decaffeinating process will decrease the amounts of some photochemical - however, boiling and steeping tea are more likely to lead to decreases in anti-oxidants. I'm sure what you are consuming is still very healthy.

a-CO2 (supersaturated)\nb-There are many, however judging from all the answers I'd guess CO2 is what your are looking for here.\nc-CO2 (frozen)\nd-CO2 (freon [or some other fluorocarbon] in the old days, but no more!)\ne-CO2 (waste from yeast fermenting)\n\nJust for fun, other decaffeinates are:Methylene Chloride, Ethyl Acetate, Carbon, and Triglycerides.\n\nGet an "A".

When they consume tea the tea has been seeped of caffeine. You can decaffienate tea by seeping a tea bag until it makes a dark tea, pour out that cup and make a new cup, it wont have caffeine in it.

You can carry a 1/2 gallon milk jug around, filled with 1 part regular strength coffee, and 3 parts water.  Sip at it throughout the day, and it will speed up your metabolism some.\n\nIt's probably not healthy to drink that much coffee in a day though.  proceed at your own peril.

If you are a coffee drinker,try holding a mouth full in your mouth for a few minutes and then, spit it out..The heat will loosen up the glue..Been there,know what you're going through and it will get better..Try not to use as much glue next time, sometimes this works too.\nHave you tried the "Fix-a-dent with control?" It comes with scope flavor.I have found that it isn't as hard to get off as the original brand..Plus it leaves your mouth with a fresh taste.The original tasted  like "Elmer's glue" yuk!!!!

Unsweetened is just fine. Check the label and see what else is in it though. I love making my own iced tea with decaf Green Tea. That is very good for you.

Like the doctors told me, caffein is very bad for the kidneys. Contrary to what the other writers have said, I've always been told there is less caffein in tea, so I don't know what to tell you. There is decaf tea as well as coffee, which do you prefer? They taste the same as regular. Watch your soda intake, loads of caffein... especially MountainDew!
