Verfahren zum Gewinnen eines im wesentlichen Theaf lavin und/oder Theaflavingallate enthaltenden ProduktesMethod of Obtaining an Essentially Theaf Lavin and / or product containing theaflavallate
Die Erfindung betrifft die Gewinnung von wertvollen Produkten aus Teeabfall und die Verwendung dieser Produkte bei der Herstellung von schwarzem Tee.The invention relates to the recovery of valuable products from tea waste and the use of these products in the production of black tea.
Der feine Staub, der sich in Pabrikationsanlagen für Tee am Boden und an den Decken ansammelt und als "Teeflaum" ("tea fluff") bekannt ist, enthält wertvolle Materialien, die erfindungsgemäß isoliert und zur Verbesserung der Qualität des Tees verwendet werden. Auch Teestengel, die normalerweise verworfen werden, können in ähnlicher Weise zur Gewinnung dieser wertvollen Materialien verwendet werden. Der Teeflaum, die Teestengel und ähnliche Materialien werden im folgenden "Teeabfall" genannt.The fine dust that is found in manufacturing plants for Tea accumulates on the floor and on the ceilings and is known as "tea fluff", contains valuable Materials that are isolated according to the invention and used to improve the quality of the tea. Even Tea stems, which are normally discarded, can be used in a similar manner to extract these valuable materials be used. The tea fluff, the tea stalks and similar materials are hereinafter referred to as "tea waste" called.
Teeabfälle enthalten Theaflavine und Theaflavingallate, die für die leuchtend goldene Farbe des aus schwarzem Tee herstellten flüssigen Tee verantwortlich sind. Es wurde gefunden, daß die Qualität von schwarzem Tee durdi Zugabe der Theaflavine oder Ihrer Gallate zum Tee während einer '-bestimmten Herstellungsotufe gesteigert wer-Tea waste contains theaflavins and theaflavallates, which are responsible for the bright golden color of the liquid tea made from black tea. It The quality of black tea has been found to be by adding the theaflavins or your gallates to the tea while a '-specific manufacturing stage can be increased

den liann. Erfindungsgemäß wird schwarzer Tee von verbesserter Qualität durch Zugabe von The&flavinen und/oder Thea,-flavingallaten oder einer Mischung, die diese durch Lösungsmittelextraktion von Teeabfall gewonnenen Substanzen enthält, hergestellt.the liann. According to the invention, black tea is improved from Quality through the addition of The & flavines and / or Thea, -flavingallates or a mixture containing these substances obtained by solvent extraction of tea waste contains, manufactured.
Theaflavin und die entsprechenden Ester der Gallensäure (Gallate) können aus Teeabfall durch Lösungsmittelextraktion gewonnen werden. Ein Verfahren, das sich als besonders ergiebig gezeigt hat, besteht darin, daß der Teeabfall mit wasserhaltigem Äther extrahiert wird, wobei das Wasser ein wesentlicher Bestandteil im Extraktionsmittel ist. Es wurde „_ gefunden, daß während der kontinuierlichen Extraktion von w Teeabfall mit wäßrigem Äther sich das gewünschte Produkt während der Extraktion aus dem ätherischen Extrakt abscheidet. Andere organische Lösungsmittel und insbesondere andere hydroxylhaltige Lösungsmittel können für die Extraktion verwendet werden.Theaflavin and the corresponding esters of bile acid (gallates) can be made from tea waste by solvent extraction be won. One method that has been shown to be particularly productive is that the tea waste with water-containing ether is extracted, the water being an essential component in the extractant. It was "_ Found that during the continuous extraction of w tea waste with aqueous ether, the desired product separates from the ethereal extract during the extraction. Other organic solvents and especially other hydroxyl-containing solvents can be used for the extraction be used.
Teeflaum oder Teestengel werden kontinuierlich in einem Soxhlet-Apparat mit Diäthyläther, der 5 bis 10 VoI.$> Wasser enthält, extrahiert. Nach einigen Tagen hat sich im Soxhlet-Kolben ein rotbrauner Peststoff abgeschieden, der nach dem Dekantieren des Äthers gewonnen wird. Die Ausbeute an Peststoff liegt zwischen 4 und 5 %$ bezogen auf das Gewicht des extrahierten Materials, und besteht im wesentlichen aus *Theaf'lavingallaten mit geringeren Mengen an Theaflavin und Koffein. Dieses Gemisch ist in heißem Wasser oder kaltem Aceton löslich.Tea fluff or tea stalks are continuously extracted in a Soxhlet apparatus with diethyl ether containing 5 to 10 vol . Of water. After a few days, a red-brown pest has deposited in the Soxhlet flask, which is obtained after decanting the ether. The pesticide yield is between 4 and 5 % based on the weight of the extracted material, and consists essentially of * Theaf'lavinallates with smaller amounts of theaflavin and caffeine. This mixture is soluble in hot water or cold acetone.
Das Verfahren des Beispieles 1 wird wiederholt, doch wird der Teeabfall im Gemisch mit Glasbruch oder Kieselgur eingesetzt. Es zeigt sich, daß mit einem solchen Gemisch der Ätherfluß durch den Teeabfall mit größerer GeschwindigkeitThe procedure of Example 1 is repeated, but the tea waste is used in a mixture with broken glass or kieselguhr. It turns out that with such a mixture the flow of ether through the tea waste is faster

erfolgt und die für die Extraktion erforderliche Gesamtzeit herabgesetzt wird.occurs and the total time required for extraction is reduced.
Das durch Lösungsmittelextraktion aus dem Teeabfall gewonnene Produkt kann schwarzem Tee in verschiedener Weise zur Qualitätsverbesserung beigegeben werden. Beispielsweise kann das isolierte Material in Form einer wäßrigen oder anderen geeigneten Lösung oder Suspension auf den Tee versprüht werden, bevor dieser während seiner Herstellung in an sich bekannter Weise getrocknet wird.That obtained from the tea waste by solvent extraction Product can be added to black tea in various ways to improve its quality. For example the isolated material can be sprayed onto the tea in the form of an aqueous or other suitable solution or suspension before it is dried in a manner known per se during its production.
