Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Das Verfahren zur Herstellung von Kaffeeextract beruht auf der Verwerthung folgender durch Untersuchung der .flüchtigen und nicht flüchtigen Extractivstoffe des Kaffees gewonnenen Thatsachen. Es ist bekannt, dafs bei längerem Kochen ein Kaffeedecoct sein Aroma . nahezu völlig verliert und eine bitter und brenzlich schmeckende Flüssigkeit darstellt.The process for the production of coffee extract is based on the utilization of the following obtained by examining the .volatile and non-volatile extractives of coffee Facts. It is known that a coffee decoct will develop its aroma when it is boiled for a long time . is almost completely lost and is a bitter and burnt-tasting liquid.

Condensirt man die bei dieser Procedur auftretenden Dämpfe, so ist das Destillat ein trübes, zum Theil angenehm, zum Theil unangenehm riechendes Liquidum. Der angenehme Geruch ist durch das Kaffeearoma, der unangenehme durch basische Producte und hochsiedende Kohlenwass'elsTölSe'rrJ'eHin^t. Destillirt man das gewolnn"ene~Destinät~ nochmais, und zwar zweckmäfsig unter gelinder Ansäuerung mit einer nicht flüchtigen Säure, z. B. Schwefelsäure, sowie ferner zweckmäfsig unter Anwendung des Vacuums, so geht die das specifische Kaffeearoma bedingende Substanz fast völlig rein in das erste Viertel des Destillats über, während die das Aroma verunreinigenden Bestandteile theils im Rückstand, theils in den ferneren Antheilen des Destillats verbleiben.If one condenses the vapors occurring during this procedure, the distillate is a cloudy, partly pleasant, partly unpleasant-smelling liquid. The pleasant smell is caused by the coffee aroma, the unpleasant one by basic products and high-boiling hydrochloric oils. If one distills the obtained destiny again maize, expediently with mild acidification with a non-volatile acid, e.g. sulfuric acid, and further expediently with the application of the vacuum, then the substance causing the specific coffee aroma is almost completely pure over the first quarter of the distillate, while the constituents contaminating the aroma remain partly in the residue and partly in the remainder of the distillate.

Verdampft man andererseits den durch systematische Erschöpfung des gebrannten Kaffees gewonnenen Kaffeeauszug zunächst über freiem Feuer schliefslich im Vacuum, wobei die flüchtigen Antheile zur Condensation gebracht werden, so resultirt bei Extractconsistenz ein intensiv bitteres, nicht aromatisches Product, das, in angemessener Weise mit kochendem Wasser verdünnt, nicht entfernt; die Annehmlichkeiten des Kaffeegeschmacks aufweist. Rührt man den dickflüssigen Extract hingegen mit dem gereinigten Destillat, welches das Kaffeearoma in concentrirter Form enthält, an, so resultirt ein in Wasser klar löslicher,, mäfsig dünnflüssiger Syrup, welcher, mit heifsem Wasser verdünnt, sofort eine völlige Imitation eines frisch bereiteten Kaffeeaufgusses darstellt.On the other hand, if one vaporizes the result of the systematic exhaustion of the brewed coffee Coffee extract obtained first over an open fire and finally in a vacuum, with the volatile If parts are brought to condensation, an intensive result results in the case of extract consistency bitter, non-aromatic product which, appropriately diluted with boiling water, not removed; has the convenience of the taste of coffee. One stirs the thick extract, on the other hand, with the purified distillate, which gives the coffee aroma contains in concentrated form, the result is one which is clearly soluble in water, moderately thinner Syrup, which, diluted with hot water, is immediately a complete imitation of one represents freshly prepared coffee infusion.

Der bisherige Mifserfolg aller Fabrikate sogenannter Kaffeeextracte ist lediglich in dem Umstände zu suchen, dafs man den flüchtigen Substanzen des Kaffees und insbesondere der Reinigung des specifischen Aromas des Kaffees keine genügende Aufmerksamkeit zugewendet hat. Die bisherigen Kaffeeextracte sind aromalose Auszüge verschiedener Concentration, denen das Specifische des Kaffeegetränkes völlig abgeht. The previous failure of all brands of so-called coffee extracts is only in that To look for circumstances to avoid the volatile substances of coffee and especially of the Not paying enough attention to purifying the specific aroma of coffee Has. The previous coffee extracts are aroma-free extracts of various concentrations, which the specifics of the coffee drink are completely absent.
