Is the caffeine that is removed from coffee beans during the decafination process used to "spike" .... Is the cafine that is removed from coffee beans during the decafination process used to "spike" cafinated beans, thus making coffe that much more addictive for coffee lovers, keeping the coffers full in places like Starbucks? You know, like the tobacco companies did with the nicoteen in cigarettes.
Silly chick replied: "No. It's not re-used at all."
kistin14 replied: "I don't think that is possible. But it would be a good idea. Coffee lovers stay because they like the jolt, and the taste of coffee."
Can you remove coffee (caffeine) from you body/system? I am a college student and drink coffee to keep me awake. It also helps when studying. So when I don't drink coffee, I get tired. To solve this problem, I drink coffee.
Can you get rid of coffee (caffeine) from your system where you won't have a craving for coffee or feel the need for coffee to keep you awake?
I know that people who uses drugs can go to the hospital to let them detoxify the body and go through withdrawal within a couple of hours. Can the same thing be done with coffee?
Elizabeth P replied: "First of all you have to stop drinking drinks with caffiene. Drink a lot of water to flush your system of the caffiene. Because caffiene is a drug and you were probably addicted or at least dependant on it, you will feel tired and get headaches from the withdrawal which you will just have to deal with."
paige_9_99 replied: "Just go off caffiene for a week and dont drink it when you have cravings. You dont need to detox from caffiene because there are no real withdrawl symptoms other than headaches which arent dangerous."
What percentage of caffeine must be removed for a coffee to be called 'decaf'? Plz Help - Emergency!
allfoamnobeer replied: "97%"
Andrea replied: "Usually about 95% of the caffeine is removed to make decaffeinated coffee. Since the average cup of regular coffee has 100 mg of caffeine, the average cup of decaffeinated coffee contains about 5 mg of caffeine. However, it seems to depend on the brand."
Frank L replied: "well it is called decaf so im guessing 100percent"
Me Want Cookie! replied: "97-99.9% caffeine free"
how do you remove caffeine from coffee? or even tea for that matter. for an investigation

European Process
Most decaf coffees are made using a chemical process first used in Europe. This process involves soaking the beans in water and then "washing" them in methylene chloride to absorb the caffeine from the bean. After this, the beans are rinsed clean of the chemicals, dried and shipped to the coffee roasters. The advantage of this method is that it provides decaf coffee with more flavor than the Swiss water processing. Although there is virtually no trace of any chemicals left in the bean after roasting, some people are uncomfortable knowing that the coffee they are drinking was chemically processed.
Swiss Water Process
The second method is known as "Swiss water processing". This process uses no chemicals, but rather hot water and steam to remove the caffeine from the coffee. The "life" of the bean is taken into the water, and then the water solution put through activated charcoal filters to remove the caffeine. Once the caffeine is removed, these same beans are then put back into the decaffeinated solution to re-absorb everything except the caffeine. The beans are then dried and shipped to the roasters. The disadvantage is that the water processing removes more than just the caffeine. Some of the oils from the coffee bean are removed as well, making it less flavorful."
ebiyedinak replied: "The only way the content of caffine can be reduced is by the addition of milk to dissolve the caffine."
mshoagie@verizon.net replied: "Why would you go through all that? Just buy decaf."
Why is Ethyl acetate used to remove caffeine from coffee beans? Is there another safe way to doing this? Ethyl acetate
is used as a solvent in oil-based lacquers and enamels (especially in polyurethane finishes) How can it be safe to consume decaf coffee when this is used to remove the caffeine? Are there alternatives (aside from just not drinking decaf coffee)(not an option LOL)
Whoa I;d like to have some fun while I am still here on planet Earth!! No chocolate ? No coffee at all? Actually I am not a big coffee drinker I'd say 2-3 cups per day if that. I am a tea drinker but prefer the green teas, white tea variety and some of the flavored decaf teas as well. I still need some "stimulate" to float my boat and get out of bed in the a.m. I keep hearing a coffee brand on radio ads that uses the "water filtering" method but always miss the brand name.(I am in Canada)anywhoo thanks to all for your 2 cents worth!
ginabobina replied: "have you tried doing some research? I cut coffee off for a few weeks. Sure, you might crave it for a while, but maybe you should just have naturally decaffeinated tea for a while. It is better for you anyway, in my opinion. I only like coffee from a french press, anyway. Try some chai tea, yum! and don't forget your other legal drugs. Alcohol, tobacco, Sugar, and caffeine are all the legal drugs, I believe. You should try cutting those off a little too. :) I think chocolate is a stimulant also"
Soda replied: "There is an alternative by using water extraction of caffeine in the beans. It takes about 8 hours longer and removes 98% of the caffeine. (It's pricier because of this method). There is also carbon dioxide extraction of the caffeine and genetic engineering for zero caffeine producing coffee beans. You'll just have to read labels to see which compainies are doing this. Organic beans have the healthier methods for caffeine extraction. One way at home that ends up causing a bit less flavor is to take beans and brew them, dump that coffee out and rebrew the used ground with fresh water. It does reduce the caffeine amount but I am not sure by how much."
nicholeati replied: "there are decaf coffees that use water to extract the caffine - Lavazza in Italy is one of them -"
Mags replied: "It is a bit scary to see how many foods are processed using a solvent process.
There is good news which you can read about a low-caffeine coffee been being discovered in 2004 which may prove to be a substitute. (Coffea arabica)
Moreover, this may be an instance where genetic engineering might be safer that the alternative.
Take a look at the site below:
Also check the International Coffee Organization where you can find more information about decaffeinating methods. "There are four methods of decaffeination, according to which substance is used to extract the caffeine; Water Ethyl Acetate Supercritical or Liquid CO2 Methylene Chloride"
Cheers!"
how would dichloromethane affect the extraction of caffeine from coffee? Tea has very few components, other than caffeine, that dissolve in dichloromethane. Coffee contains a number of volatile, oily compounds. How would the dichloromethane affect the extraction of caffeine from coffee, if we used the same procedure (adding dichloromethane, centrifuging, removing the base layer and then setting up a filtration after repeating the addition and removal steps 4 times) we used to extract caffeine from coffee that we used to extract caffeine from tea?
Green replied: "I'm not sure what you are asking. I cant see anything wrong with your reasoning, so yes, you could probably use the same procedure.
DCM would still extract the caffeine, your oily compounds are most likely terpenes of one sort or another and non-polar, so have a poor affinity for the DCM.
I believe DCM was used as solvent for decaff coffee in the distant past, However, these days they use CO2 gas as the solvent.
Sorry that I can do little more than just agree with you."
