When scientists established that caffeine is noxious to health, thousands of coffee-achievers on all to the world were inconsolable. But the coffee industry did not allow the fans to become despondent therefore beskofeinovy coffee — dekaf was invented. It kept the lion's share of advantages of this fragrant drink, but at the same time got rid of the main part of its shortcomings.
it is so harmless dekaf and that is behind this name — we will consider further in our article.
Whether there is it?
Actually completely it is impossible to get rid of caffeine in coffee beans: kind of cleaning was not carried out, all the same 5-10 mg of this substance remain. However you should not worry — at the same quantities alkaloid is present also at other drinks, for example, in harmless cocoa.
But, nevertheless, the dekofeinization is capable to remove the majority of molecules of caffeine in various ways about which producers are obliged to report on packings with products.
As coffee without caffeine turns out or What is a dekofeinization
There are several types of purification of coffee beans which differ among themselves with the cost of technology and safety for the further consumer. In certain cases producers save on the equipment, and the product which can do much harm to health as a result turns out.

Swiss method (Swiss Water)
This way of processing of coffee beans was developed in 1979, however still it is considered one of the most effective as it allows to remove 99.9% of caffeine.
The procedure in this case is very simple:
- grains are filled in with water into which in the course of upholding pass alkaloids and aromatic oils;
- then water passes through special filters, leaving on them caffeine;
- the flavored purified liquid is returned to grains again and process repeats once again,
In terms of ecology this method the best, however it very expensive, and this factor affects the price of a ready dekaf.
Direct method
Often this way is called European or traditional as it was invented by the first.
Its technology is quite simple: at first grains presoak in hot water, after them lower in solvent to remove caffeine. Then raw materials are rinsed with boiled water and well dried up.
As solvent use methylene dichloride (which is also applied to processing of plastic, fats) or ethyl acetate (liquid on the basis of vinegar and alcohol).
Important! The main minus of this way also consists in solvent: regardless of what substance is used for caffeine elimination, it is completely impossible to wash up it from grains, a part of solvent all the same will remain as a part of coffee.
Indirect method
This method of processing is similar to direct, but has the characteristics.
In this case primary soaking of grains is carried out too, then there is a processing by solvent, but at the same time the taste and aroma of coffee remain. Thus carry out several cycles therefore the balance between water and composition of grains is leveled.
Thanks to it washing away of useful oils and vitamins from beans stops. This technology is more expensive traditional processing, but as a result and the products turn out more quality.

Besides, after such processing as a part of coffee there are no foreign impurity and chemicals so nothing threatens health of consumers.
