What decafe non-caffeinated coffee, decaffeinated coffee processing process

What is caffeine?

Coffee, green tea, cola, etc. originally contained caffeine. The effects of caffeine, however, are already known, such as awaking motivation upward and lethargy, diuretic effects or fetal effects, inhibition of iron absorption, because there are many adverse aspects such as light-dependent diseases caused, such as headaches, especially if you should avoid pregnancy.

Or delete foods and beverages that contain raw caffeine and decaffeinated ones, such as caffeine that is not added at the manufacturing stage, and you say you did not intentionally contain caffeine. It is also commonly used with the name "decaffeinated" or "decaffeinated," if it is decaffeinated coffee, you say (rarely, if ever) that coffee is decaffeinated.

How to make changes in caffeine

Since coffee beans naturally contain caffeine, caffeine naturally enters the liquid if roasted and extracted. Caffeine can currently be drunk green, so it's safe to drink even if you don't want caffeine or get pregnant. The main ways to remove caffeine are as follows.

Swiss Water Treatment Act

This is a method that uses water to extract only the caffeine component. Water is passed through a tank containing green coffee beans, caffeine is removed from the extracted aqueous solution with an organic solvent, and then recycled to the green bean barrel again. Since the organic solvent does not come into direct contact with the raw beans, it is relatively safe and has the advantage of suppressing the outflow of other components. It is currently widely used as a mainstream peeling method because caffeine can be removed cheaply and effectively.

organic solvent method

This is a method of extracting caffeine components using drugs. Although caffeine can be removed by soaking coffee green beans in an organic solvent, other components also flow out, and thus there is a disadvantage of shedding in terms of taste and aroma. This method is generally formulated by water law, so it can be cheaply refurbished, so it is still a very convenient method, and it is still partial. However, residual organic solvents may have adverse effects on the body, so decaffeinated coffee with organic solvents cannot be sold in Japan.

carbon dioxide method

It is also known as supercritical carbon dioxide extraction and is the latest method of caffeine extraction. This mechanism is a bit difficult, but increasing the pressure and temperature of carbon dioxide will result in a state known as supercritical fluid with gas and liquid properties. With green coffee beans, only the caffeine component can be removed, because it does not use drugs, so it is the safest method of caffeine removal. However, due to the high cost of removal, the price of coffee beans is also high.

About the taste of decafé

When asked about caffeine in coffee, and it is very easy to image, such as gas passing through coffee, in fact not so. Of course, in the removal of caffeine, so caused a slight outflow also than caffeine and other components, but we can not exactly the same, recently, there have been technological advances, it has become quite good taste process.

Because caffeine itself has a bitter taste, when you drink coffee, it will have less bitterness and a refreshing taste. Conversely, among those who dislike bitter coffee, many prefer coffee with less caffeine than regular coffee.
