People usually associate caffeine with their morning coffee or tea; however, “It can be found in a large portion of what we eat and drink and is consumed daily by an estimated 80% of children and adults in the United States (Barone & Roberts, 1996)”. The study by Childs and de Wit from the University of Chicago suggests that there might be a correlation in the variety of caffeine pills that have been given to some participants in past experiments (Childs & de Wit, 2008). In those studies the participants were given a caffeine pill that also has other herbal supplements which resulted in adding confounding properties to the study. The experiments where participants were given a true caffeine pill with 100% caffeine and no addit...
Caffeine, probably the most widely used drug, is a potent pharmacological and psychotropic agent. The white, bitter-tasting, crystalline substance was first isolated from coffee in 1820. The origins of the words, caffeine and coffee, reflect the spread of the beverage into Europe via Arabia and Turkey form North-East Africa, where coffee trees were cultivated in the 6th century. Coffee began to be popular in Europe in the 17th century, and plantation had been established in Indonesia and the West Indies by the 18th century. Nowadays, it is a regular component of the diet for most people. Caffeine is considered as a cheap drug that could be found in many nature sources such as tea, chocolate, and cocoa.
The extraction process was used to extract crude caffeine from a black tea bag, and sublimation was used next to purify the crude caffeine. The vital result from the experiment is the amount caffeine obtained, but as a result of errors during the experiment, no caffeine was obtained. This lab could be enhanced in several ways. The proper tools should be provided to ensure that no error is a result from the lab materials and the directions of the experimental procedure should be
Waking up to a hot cup of coffee, relishing the cool tingling sensation of a cola with your lunch, or relaxing in the afternoon over a cup of tea, all have similar ingredient caffeine. Caffeine has been consumed ever since the 2700 BC, with its conjunction in tea, for the Chinese Emperor Shen Nung. In 575 AD, the first use of coffee beans where in Africa where it was used as currency and food. Even more today, caffeine consumption has become an integral part of millions of people's daily lives. According to David Weaver, "Caffeine and theophylline are among the most widely consumed neuroactive substances. These drugs are consumed most frequently in beverages, but also are present in certain over-the-counter diet aids, 'alertness tablets' some analgesic preparations, and in chocolate, and are also administered for therapeutic effects." The problem with caffeine is that many students/adults are uneducated about this subject. Stereotypically, caffeine has been labeled harmless. However, most caffeine consumers have no idea how they react to their body chemistry, the chemical mechanism, the hidden side-effects, and the actual daily amount which they intake.
In order to obtain crude caffeine from the contents of a tea bag, the processes of extraction was used to remove the caffeine from 2.673 grams of tea leaves. The caffeine was extracted in a separator funnel using dichloromethane and water. The experimental procedure called for three separate extractions using 5 mL of dichloromethane each time. However, one large extraction using 15 mL of dichloromethane was performed due to a misunderstanding while reading the directions. Therefore, the amount of crude caffeine obtained from extraction was very small, and many more impurities were also extracted. The amount of crude caffeine extracted was 0.094 g. When this value is compared to total mass of the tea leaves, the percent yield was determined to be 3.52 %. According to caffeineinformer.com, tea seeped for 5 minutes should contain around 0.047 g of caffeine. When the extracted value is compared to this
Caffeine and coffee are a daily part of life for most people in modern society. The discovery of the coffee bean is said to have been in Ethiopia, when a sleepy eyed goat herder noticed his goats eating red berries, he then noticed the effect it had on them as they jumped and danced around him. He then tasted the berries and his eyes opened wide, he took them to the local village who also liked it and in particular the monks who used the berries to keep them awake during meditation.
Coffee is much more than the hot, black liquid that millions of us drink every morning; it is a worldwide commodity that has been keeping us awake for hundreds of years. It seems that a coffee shop can be seen on every shopping center and a coffee pot in every work break room. Our lives today revolve around coffee, regardless if we drink it or not, and ironically it not only stimulates of senses but also our economy. We wouldn’t be able to imagine Bill Gates not with his cup of coffee making Microsoft in his garage, or Henry Ford waking up early to perfect the auto industry and the assembly line. The economics of coffee may not be a simple one to study, but it is one you will be kept up all night learning about.

Caffeine is the single most widely consumed psychoactive substance in the United States (Einöther & Giesbrecht, 2013). According to Einöther and Giesbrecht (2013), 80% of the world’s population consumes caffeinated products every day, with coffee and tea being the primary sources. In the recent years, the demand for
It appears that coffee was discovered in the ninth century after a goatherd named Kaldi found the berries that his sheep were eating made his sheep and then himself unusually energetic. The stimulating berries after being roasted and brewed eventually evolved into coffee as a hot drink and became popular throughout Arabia, Turkey and Europe by the seventeenth century. (Thomson, 2006). In 1901, the first successful technique for manufacturing a stable powered product was invented by Sartori Kato, a Japanese chemist living in America. Kato received a patent for his invention and the instant coffee history was made. He then set up his own coffee company named Kato Coffee Company in Chicago (Stefanie, n.d.).
Coffee is the first thing that people associate with instant energy on a groggy morning. “In the U.S., coffee is king of beverages” (Reinke) Research has been done that has named coffee as an addiction to the people who consume large quantities of it. Coffee was named the top source of antioxidants. This is partly because of the amount consumed each day. Some of the antioxidants that coffee has are quinines and chlorogenic acid. It also contains trigonelline, an antibacterial compound. This is where coffee acquires its delicious aroma. Now let’s step back for a minute and just think about how much caffeine people consume. In an 8oz cup of coffee it has about 85 milligrams of caffeine. This is about double the amount that tea contains. Studies have shown that caffeine stimulates the brain and nervous system. This is where you get that energized feeling. After about the third cup, knees start to bounce, pens are clicking and people start running laps around the office. Caffeine can become addicting if you drink too much. Coffee can become that addictive habit people are unable to shake.
Millions of Americans begin each day by consuming the most widely used drug in the United States: Caffeine. Over 90% of United States adults consume caffeinated food or beverages on a daily basis and over 50% take more than the recommended amount. Our innocent daily ritual can turn into an addiction for some because many do not realize that caffeine is even a drug let alone the effects it can have on their bodies. Its use it becoming more and more prominent in our society. It’s not uncommon to walk outside and see a Starbucks or coffee shop on each corner. Innovative foods are coming out infused with coffee, and energy drinks are being pushed at every angle. Caffeine to many is a necessity to wake up in the morning and for others to stay up all night. This is dangerous because people are not only becoming more and more dependent on coffee drinks and energy drinks but they are beginning to ingest more of it each day and are now mixing it with other drugs that can be life threatening. Proper knowledge is important when taking any drug including one that the FDA considers to be a safe multi-purpose food substance and education is the key.
