A process for the preparation of a drink based on alimentary vegetable extracts as well as the drink got by such a process are described. Among the starting vegetable products the roasted coffee will be considered, even if the process according to the invention is also fit for preparing drinks based on roasted seeds, tea, cocoa, barley, chicory, dried figs, as well as aromatic and officinal herbs and seeds and, finally, Java jute (karkadé) and mate. The process provides the micronization of the starting product by its crushing into elementary particles, some of which are separated. The aromatic components are then extracted under pressure by means of a suitable solvent. Afterwards it goes on with the separation of the powder from the elementary exhausted particles by the solvent through a centrifugation step from which is then goes on to the separation of a liquid extracted from the vegetable in question, to be utilized exactly the same or mixed with a second substance, which, in the case of coffee, can advantageously be some milk for getting a "cappuccino". The mixture so got is finally sterilized and packed in an aseptic way getting therefore a long-preservation drink. |
