Use of water

DemusAqua is a new decaffeination method that uses water and active carbon for the extraction of caffeine. It is a procedure that exploit only water as the extraction solvent; the water and the coffee are put into contact at a certain temperature that allows the start of the extraction process. The activated carbons are used for the extraction of caffeine from water in such a way that the private aqueous solution of caffeine can then be concentrated and reincorporated in the coffee.
