‘Decaffeinated coffee’ is that type of coffee gone through the decaffeination process. Also known as ‘Decaf Coffee’. The decaffeination coffee process removes caffeine from coffee beans, tea leaves, cocoa, or any other material which contains caffeine. But the process does not remove all the caffeine.
If you are a coffee lover, but as per doctor’s suggestion, having much caffeine is not good for you, then decaf coffee is the excellent solution. Decaf coffee contains a very small amount of caffeine in it. The amount of caffeine in decaf coffee is 1-2% compare to the original caffeine. The amount can be up to 20% based on requirements.
As per requirement from the United States, the amount of caffeine in decaffeinated beans should be a maximum of 3% of the original amount. The amount varies from country to country.
In 1820, A German chemist, Friedlieb Ferdinand Runge isolated pure caffeine from the coffee bean. But he did not try out the isolation commercially.
First commercially successful decaffeination process performed in 1903. German merchant Ludwig Roselius and his co-workers completed the process. They later patented it in 1906.
Earlier, decaf coffee was sold by the name of “Kaffee HAG” and they still do so but under a different company. The decaffeination process extracts caffeine from green beans. But strength or flavor stays intact. There are several methods to perform the process.
Decaffeinated Coffee A.K.A. Decaf Coffee
Coffee is the most popular beverage in the world. But for personal preferences or health reasons, sometimes folks have to limit their caffeine intake, i.e., limit their coffee consumption. For those people who’re in that dilemma, decaf coffee has been an excellent alternative. It’s just like regular coffee, except the caffeine amount has been significantly reduced.
At least 97% of caffeine is removed from the coffee beans to make it decaf. So, decaf is not fully caffeine free. There are multiple ways of decaffeinating. Decaf processes involving water, organic solvents, or carbon dioxide are more prevalent. A popular decaf process involves carbon dioxide or a charcoal filter known as the Swiss Water Process.
The nutritional value of decaf coffee is almost equal to that of regular coffee. Except the caffeine content only. But the taste and smell may become a little milder. The color may also change.
Each 180 ml (6 oz.) serving of decaf coffee contains 3–7 mg of caffeine. On the other hand, regular coffee contains about 70–140 mg of caffeine in 180 ml of coffee.
Advantages of Decaf Coffee
Decaf coffee is more pleasing to those who have sensitivity to the bitterness and the regular smell of coffee.
Decaf coffee lets you escape the negative side effects of regular caffeine content. People who suffer from insomnia, high blood pressure, restlessness, heart palpitations, and anxiety find that decaf is their solution.
Caffeine causes health problems through its stimulant, diuretic, and acidic properties—causing heartburn and bowel problems. Decaf coffee lessens those caffeine effects but still incorporates coffee into your day.
Caffeine gives restlessness and nervousness (colloquially known as “jitters”). For those who experience jitters, switching to decaf is one of the ideal solutions.
The Drawbacks of Decaf Coffee
Some decaf coffee preparations involve methyl chloride. It’s a chemical found in paint strippers, and high exposure to this chemical can cause severe neurological effects.
Small amounts of this chemical are safe, but if you care to avoid it altogether, just make sure to check the labels of the decaf coffee before you buy it.
Multiple medical studies support the fact that decaf coffee increases cholesterol levels in humans. So, if you experience cholesterol problems, talk to your doctor and stop drinking decaf coffee.
Some of the beneficial effects of regular caffeinated coffee are absent in decaf. Abilities such as improving mood, reaction time, memory, mental function, metabolic rate, athletic performance, and reducing the risk of mild depression are absent in decaf coffee.
Processes of Decaffeinated Coffee
Organic Solvents Processes
- Firstly, steams unroasted green beans.
- Rinses the beans with methylene dichloride or ethyl acetate solvent.
- Repeats 8 to 12 times until the requirement meets.
- Also referred to as water processed.
- Beans stay in hot water for several hours. Water soaks caffeine content.
- Methylene dichloride or ethyl acetate solvent extracts caffeine from the water.
- The Same water is used for a new batch.
Supercritical Carbon Dioxide (CO2) Processes
Swiss Water process
- Uses Green Coffee Extract (GCE) mechanism for the caffeine extraction
- Takes 8-10 hours to meet the requirements
- Beans stay in hot water for several hours.
- Then, beans get transferred to another container with coffee oil.
- Triglycerides in the oils remove the caffeine
- Separates beans from oil and dry.
There is probation for manufacturers to test newly decaffeinated coffee beans. You may mix up low caffeine coffee with decaf coffee. But actually, they are not the same.
Low caffeine coffee naturally has a low level of caffeine without any process performed. There can be a lot to discuss the difference between low caffeine coffee and decaf coffee. On an important note, as low-caffeine coffee beans originally contain a very moderate amount of caffeine, they are a good choice for decaffeination.
“Decaffito” is natural coffee beans growing without caffeine. The plant is called “Coffea Charrieriana”, found in Cameroon, is only known natural caffeine-free plant.
