Description

Die Erfindung betrifft ein Verfahren zur Verminderung des Chorogensäuregchaltes in Rohkaffeebohnen.The invention relates to a method for reducing the chorogenic acid content in green coffee beans.

Es gibt viele Menschen, die magenempfindlich sind und nach dem Genuß von Kaffee Magenschmerzen bekommen. Die Chlorogensäure gilt u. a. als Ursache der Unbekömmlichkeit von Kaffee bei Personen, die magen- und darmempfindlich sind. Seit Jahrzehnten wird deshalb bereits nach einem brauchbaren Weg gesucht, um Chlorogensäure, die in Kaffeebohnen zu 4% enthalten ist, zu vermindern, vgl. T r i 11 i c h, »Rösten und Röstwaren« (1934), Seiten 228 und 229.There are many people who have sensitive stomachs and have stomach pain after drinking coffee receive. The chlorogenic acid applies inter alia. as the cause of the indigestibility of coffee in people who are sensitive to stomach and intestines. For decades, therefore, a useful way has been found sought to reduce chlorogenic acid, which is 4% in coffee beans, see T r i 11 i c h, "Roasting and Roasted Products" (1934), pages 228 and 229.

Aus der GP-PS 8 67 613 ist es bekannt, Gerb- und Bitterstoffe, wie Leucoanthocyanine, aus Getränken, z. B. Bier, Wein und Fruchtsäften, durch Behandeln mit Polyamidpulver zu entfernen. Die Filtration ist jedoch mit Nachteilen verbunden, da die Absetzgeschwindigkeit des Polyamidpulvers gering ist und die Filterplatten alsbald verstopfen. Diese Nachteile sollen gemäß FR-PS 13 68541 durch die Verwendung von Polyamidfeinfasern überwunden werden. Polyamidfeinfasern sollen sich besser zur Klärung und Geschmacksverbesserung von Gerbstoffe enthaltenden Gellränken als Polyamidpulver eignen. Als spezielle Anwendungsform für Filterpapiere und Filterschichten aus Polyamidfeinfasern wird die Geschmacksverbesserung von Kaffee- und insbesondere Teeaufgüssen angeführt. Es ist dort nicht erwähnt, daß man in dieser Weise Chlorogensäure aus dem Kaffeeaufguß entfernen kann. Das Verfahren hat den Nachteil, daß dabei auch die typischen Röstprodukt-Geschmacksstoffe entfernt werden.From GP-PS 8 67 613 it is known to use tannins and bitter substances, such as leucoanthocyanines, from beverages, z. B. beer, wine and fruit juices can be removed by treating with polyamide powder. The filtration is however associated with disadvantages, since the settling speed of the polyamide powder is low and the filter plates clog up immediately. According to FR-PS 13 68541, these disadvantages are said to result from the use of fine polyamide fibers to be overcome. Fine polyamide fibers are said to be better for clarification and flavor enhancement of tannins containing tannins are suitable as polyamide powder. As a special application for Filter papers and filter layers made of fine polyamide fibers will improve the taste of coffee and especially tea infusions. It is not mentioned there that chlorogenic acid can be produced in this way can remove from the coffee infusion. The method has the disadvantage that it also includes the typical Roasted product flavors are removed.

Die FR-PS 13 08 673 betrifft die Entfernung νυη Alkaloiden aus Tabak, ohne daß andere, erwünschte Inhaltsstoffe gleichzeitig entfernt werden. Hierzu behandelt man den Tabak mit einem organischen Lösungsmittel, das gesättigt ist an denjenigen lnhaltsstoffen des Tabaks, die man im Tabak belassen will, aber eine »Sättigungslücke« in bezug auf Alkaloide aufweist. In dieser Weise extrahiert man nur die Alkaloide aus dem Tabak, nicht aber die anderen Inhaltsstoffe, die manThe FR-PS 13 08 673 concerns the distance νυη Alkaloids from tobacco without removing other desired ingredients at the same time. For this the tobacco is treated with an organic solvent that is saturated with those ingredients of tobacco, which one wants to leave in the tobacco, but has a "saturation gap" with regard to alkaloids. In this way you only extract the alkaloids from the tobacco, but not the other ingredients that you extract

Die Aktivierung des verwendeten Polyamidpulvers erfolgt in bekannter Weise.The polyamide powder used is activated in a known manner.

Beispielexample

10 kg Rohkaffee wurden durch Dämpfen aufgeschlossen und auf einen Wassergehalt von 40 bis 45% gebracht. 251 einer 13% Feststoff enthaltenden Rohkaffee-Extraktlösung, deren Chlorogensäuregehalt zuvor durch Behandlung mit 12 kg aktiviertem Polyamidpulver von 3,9% auf 2,0% vermindert worden war, wurden 4 Stunden mit dem aufgeschlossenen Rohkaffee bei 80°C in Berührung gebracht.10 kg of green coffee were broken down by steaming and adjusted to a water content of 40 to 45% brought. 251 of a raw coffee extract solution containing 13% solids, the chlorogenic acid content of which had previously been reduced from 3.9% to 2.0% by treatment with 12 kg of activated polyamide powder, were brought into contact with the digested green coffee at 80 ° C. for 4 hours.

Nach Abtrennen der Extraktlösung wurden die behandelten Bohnen auf einen Wassergehalt von 10% getrocknet.After separating the extract solution, the treated beans were heated to a water content of 10% dried.

Die analytische Untersuchung des Rohkaffees ergab folgende Werte:The analytical examination of the green coffee resulted in the following values:
