Description

Filtrierpapier für Kaffee-, Tee- oder ähnliche Aufgüsse Die Erfindung betrifft ein Filtrierpapier für Kaffee-, Tee- der ähnliche Aufgüsse.Filter paper for coffee, tea or similar infusions. The invention concerns a filter paper for coffee, tea or similar infusions.

Man hat bereits vorgeschlagen, derartige Papiere mit alkalisch reagierenden Wasserenthärtungsmitteln auszustatten, um den das Aroma und den Geschmack des Aufgusses beeinträchtigenden Kalkgehalt des Wassers zu entfernen. Es hat sich aber gezeigt, daß die alkalisch reagierenden Wasserenthärtungsmittcl die Durchlässigkeit des Papiers für den Aufguß mit der Zeit beeinträchtigen.It has already been proposed to use such papers with alkaline reactants Equip water softeners to reduce the aroma and taste of the infusion to remove the impairing lime content of the water. But it has been shown that the alkaline water softening agents reduce the permeability of the paper affect the infusion over time.

Es wurde nun gefunden, daß dieser Nachteil vermieden wird, wenn man derartige Filtrierpapiere mit einer Mischung von alkalisch reagierenden wasserenthärtungsmitteln, wie Natnumsilicat und Natriumcarbonat, sowie fein verteilten Adsorptionsmitteln, wie aktiver Kohle, ausstattet. It has now been found that this disadvantage is avoided if one Such filter papers with a mixture of alkaline water softeners, such as sodium silicate and sodium carbonate, as well as finely divided adsorbents, like active coal.

Die Adsorptionsmittel beeinflussen die Wasserenthärtungsmittel derart, daß sie das Filtrierpapier nicht mehr abdichten, so daß wie bei gewöhnlichem Filtrierpapier ein einvandfreier Durchlauf des Aufgusses gewährleistet ist. Außerdem werden von ihnen die durch die alkalisch reagierenden Wasserenthärtungsmittel in unlösliche Form übergeführten Härtebildner des Wassers sowie die gesundheitsschädlichen Röst-und Trocknungsprodukte des zu extrahieren den Genußmittels adsorbiert. The adsorbents affect the water softeners in such a way that that they no longer seal the filter paper, so that as with ordinary filter paper a flawless flow of the infusion is guaranteed. In addition, the alkaline water softeners make them insoluble Form transferred hardness constituents of the water as well as the harmful roasting and Drying products of the extract to be extracted are adsorbed.

Es ist zwar ferner bereits bekannt, Filtrierpapier für Kaffeeaufgüsse mit fein verteilten Adsorptionsmitteln, wie aktiver Kohle. für die Röst- und Trocknungsprodukte des Kaffees auszurüsten oder Filtrierpapieren neben fein verteilten Adsorptionsmittcln kapillaraktive Stoffe einzuverleiben. doch bandelt es sich hierbei nicht um solche Filtrierpapiere, die mit Wasserenthärtungsmitteln aus-' gestattet sind, so daß bei Benutzung derartiger Papiere für den vorliegenden Zweck der den Geschmack und das Aroma bceinträchtigende Kalk mit in den Aufguß übergeht. It is also already known, filter paper for coffee infusions with finely divided adsorbents such as active carbon. for the roasting and drying products of the coffee or filter papers next to finely divided adsorbents incorporate capillary-active substances. but it is not about such Filter papers which are equipped with water softeners, so that at Use of such papers for the present purpose of the taste and that Aroma impairing lime goes over into the infusion.

Zur Herstellung eines Aufgusses werden unter Benutzung von ii Wasser 10 bis 20° deutscher Härte für ein Filter von 8o mm # etwa 0,15 bis 0,5g Na2 CO3 und Ka2 SiO3 sowie etwa 3 g fein verteilter aktiver Kohle, wie Knochen- oder Pflanzenkohle, benötigt, die man dem Filtrierpapier zweckmäßig während seiner Herstellung einverleibt. To produce an infusion, using ii water 10 to 20 ° German hardness for a filter of 8o mm # approx. 0.15 to 0.5 g Na2 CO3 and Ka2 SiO3 as well as about 3 g finely divided active charcoal, such as bone or vegetable charcoal, required, which is expediently incorporated into the filter paper during its manufacture.
