How was decaffeinated coffee made? According to one legend, at the beginning of the 20th century a merchant ship sailed across the Atlantic, loaded with bags full of coffee beans. There was a storm, as a result of which water fell on the cargo and wet it. Arriving at the port of destination, the sailors successfully sold the goods, however, the buyers did not feel the aroma and the invigorating effect of the drink. Merchants did not despair and created the so-called "decaffeinated" type of drink. That is, decaffeinated coffee came out.
At the moment, this kind of drink is produced commercially in two ways. The first method is cheaper. Grains are poured with hot water with the addition of an acetic acid-based chemical solution. In this way, caffeine is absorbed. After eight hours, grains are watered with this solution so that they absorb the aroma of coffee. The caffeine content becomes 1-5%. The second method involves the addition of activated carbon. It is not possible to completely remove caffeine. However, such a drink can be consumed by people with high blood pressure.
