Decaffeinated Coffee

While caffeine is an essential part of coffee, some people just can’t handle it. For them, it’s a good idea to opt for decaffeinated coffee.

In this article, I will explain about everything decaffeinated coffee, also called decaf.

Health Concerns

Decaf coffee has its merits, although coffee drinkers are often ridiculed for it.

Most people drink coffee primarily for the sake of taste, but also to get the caffeine kick that comes with it.

It can therefore be difficult to understand why you should drink coffee without caffeine.

Caffeine-free coffee can be an advantage if you suffer from high blood pressure.

Regular coffee increases because of caffeine, your blood pressure. It is neither good nor bad unless you suffer from either high or low blood pressure.

In addition, there is no benefit from products such as coffee, cocoa, and tea that have been caffeinated.

Research says that 10% of coffee drinkers want their coffee without caffeine.

Is Decaf Healthy or Unhealthy?

The straightforward (not) answer is both.

Coffee has a lot of healthy properties. This has been documented through many research projects.

Coffee does not become unhealthy by the caffeine being extracted. But of course, it loses the good properties of caffeine.

Caffeine blocks the inhibitory neurotransmitter adenosine. It increases the production of norepinephrine and dopamine, which in turn increases the release of neurons.

It positively affects cognitive functions, such as memory, mood, energy, reaction time, and alertness. 

All of this is obviously not included in decaffeinated coffee.

You also do not get the increased fat burning that comes with caffeine intake. So you miss a 10 to 30% extra fat burn if you feel like drinking normal coffee without milk and sugar.

Because caffeine contributes to fat burning, it also increases adrenaline in the blood, which can provide up to 12% increased performance. 

So if you switch to decaf, you will not get that either.

No in-depth studies have been done on whether decaf coffee still provides protection against Alzheimer’s. But plain coffee lowers the risk of Alzheimer’s by up to 65%. Caffeine, on the other hand, protects by up to 50% compared to Parkinson’s.

Whole Beans vs Ground Coffee

Everyone unanimously agrees that using whole beans is the better choice. But some people think that there aren’t decaffeinated whole beans.

That is simply not true.

In fact, there are a lot of options when it comes to decaffeinated coffee in whole beans.

I haven’t tasted all of these, but I’ve been looking around the web for the best options and came up with a link for Amazon, where you as always can find tons of reviews and great prices HERE.

How is Caffeine Extracted?

Most people who have had a cup of decaf have probably thought about how caffeine gets out of the coffee?

Decaffeinated coffee is made by most manufacturers using chemicals.

There are four different methods to extract the caffeine from the coffee.

The challenge lies in pulling out the caffeine without the beans losing others of its many chemicals, minerals, vitamins, and antioxidants.

In addition, they must be done without the coffee losing some of its taste.

The German coffee merchant Ludwig Roselius, began in 1903 to extract coffee without caffeine.
He salted the beans and steamed the caffeine with the organic chemical Benzene. He patented the method in 1906, but it is no longer used today as Benzene is unhealthy for humans. 

According to Wikipedia.

“By inhaling the vapors you get sleepy, dizzy, confused and get a fast pulse. In severe cases, one can lose consciousness or die from the vapors.
If you take the drug into the food, it causes vomiting, stomach irritation, dizziness, sleepiness, convulsions, high pulse rate or at worst: death”.

Method 1

The direct solution-based process. It is also called the Ethyl Acetone method.

Here the beans are steamed for approximately 30 minutes, to open the bean pore.

The open beans are then bathed for approx. 10 hours in Methylene Chloride or Ethyl Acetone.

Eventually, they are steamed again to remove any excess chemicals.

If a manufacturer has not mentioned which method has been used, it is most often this method that has been used.

Method 2

The indirect solution-based process. This is called the European Method.

Here, beans are cooked in a tub for several hours. It extracts flavors and oil from the beans.

Then the beans are moved to another container where they are washed for approx. 10 hours.

This is done with Dichloromethane (DCM), Methylene Chloride, or Ethyl Acetone, which binds to the caffeine and evaporates.

The beans are now moved back to the original vessel, where they absorb most of the oils and flavors again.

Method 3

The dihydro-oxide process is also called the Swiss method.

The method was invented in Switzerland in 1933, the first method without the use of chemicals. It has been refined twice, first in 1980 and since 1988, which is the method used today.

The Swiss method is the only one that can be called organic.

Here the beans are cooked so that the caffeine is drawn into the water.

It is then filtered through a carbon filter set to take only the large caffeine molecules.

It results in green beans without caffeine or flavor but split into two tubs. One contains caffeine, while the other has all the flavors.

Now you can then add fresh beans, to the tub of flavors. Because the water in this tub is saturated with flavors, it can no longer extract from the beans and only extracts caffeine.

Once the beans have been in this tub and the caffeine is extracted, they are sifted from almost without loss of flavor.

This organic coffee is constantly tested and 99.9% caffeine is guaranteed free.

Method 4

Known as Liquid Carbon Dioxide Method, or Liquid CO2 Method.

It was invented and developed by Kurt Zosel, a researcher from the Max Plank Institute in Berlin.

Coffee beans that have been soaking until they can no longer suck water are placed in a stainless steel container. Here the water is squeezed out of the beans, with approx. 300 tons of pressure per Cm.

The Liquid CO2 method is by far the most expensive method. It is therefore also only used for very large quantities of coffee beans. So, for, less exotic and more commercial coffee, like organic Peter Larsen decaffeinated coffee.

Here is a great video explaining how the process works when making decaf coffee.
